- 50%, as specified herein, for TTL, CMOS, or Schmitt compatible inputs. Devices may be tested using any input voltage within the above specified range, but
are guaranteed to VIH (min) and V IL (max).
2. Supplied as a design limit but not guaranteed or tested.
3. Per MIL-PRF-38535, for current density ≤5.0E5 amps/cm 2, the maximum product of load capacitance (per output buffer) times frequency should not exceed
3,765 pF/MHz.
4. Not more than one output may be shorted at a time for maximum duration of one second.
5. Capacitance measured for initial qualification and when design changes may affect the value. Capacitance is measured between the designated terminal and VSS
at frequency of 1MHz and a signal amplitude of 50mV rms maximum.
6. Maximum allowable relative shift equals 50mV.
7. All specifications valid for radiation dose ≤ 1E6 rads(Si).
8. Power does not include power contribution of any TTL output sink current.
9. Power dissipation specified per switching output.
10. This value is guaranteed based on characterization data, but not tested.

DESCRIPTION
The UT54ACS74 and the UT54ACTS74 contain two independent D-type positive triggered flip-flops. A low level at the
Preset or Clear inputs sets or resets the outputs regardless of the
levels of the other inputs. When Preset and Clear are inactive
(high), data at the D input meeting the setup time requirement
is transferred to the outputs on the positive-going edge of the
clock pulse. Following the hold time interval, data at the D
input may be changed without affecting the levels at the outputs.
The devices are characterized over full military temperature
range of -55°C to +125°C.

DESCRIPTION
The UT54ACS85 and the UT54ACTS85 are 4-bit magnitude
comparators that perform comparison of straight binary and
straight BCD (8-4-2-1) codes. Three fully decoded decisions
about two 4-bit words (A, B) are made and are externally available at three outputs. Devices are fully expandable to any number of bits without external gates. The cascading paths of the
devices are implemented with only a two-gate-level delay to
reduce overall comparison times for long words. An alternate
method of cascading which further reduces the comparison time
is shown in the typical application data.

The UT54ACS86 and the UT54ACTS86 are quadruple 2-input
exclusive OR gates. The devices perform the Boolean function
Y = A B = AB + AB in positive logic.
An application is as a true/complement element. If one of the
inputs is low, the other input will be reproduced in true form at
the output. If one of the inputs is high, the signal on the other
input will be reproduced inverted at the output.
The devices are characterized over full military temperature
range of -55 C to +125 C.

DESCRIPTION
The UT54ACS109 and the UT54ACTS109 are dual J-K positive triggered flip-flops. A low level at the preset or clear inputs
sets or resets the outputs regardless of the other input levels.
When preset and clear are inactive (high), data at the J and K
input meeting the setup time requirements are transferred to the
outputs on the positive-going edge of the clock pulse. Following
the hold time interval, data at the J and K input can be changed
without affecting the levels at the outputs. The flip-flops can
perform as toggle flip-flops by grounding K and tying J high.
They also can perform as D flip-flops if J and K are tied together.
The devices are characterized over full military temperature
range of -55°C to +125°C.

16-Lead Flatpack
Top View
The conditions at the binary select inputs and the three enable
inputs select one of eight output lines. Two active-low and one
active-high enable inputs reduce the need for external gates of
inverters when expanding. A 24-line decoder can be implemented without external inverters and a 32-line decoder requires only
one inverter. An enable input can be used as a data input for
demultiplexing applications.
The devices are characterized over full military temperature
range of -55 C to +125 C.

DESCRIPTION
The UT54ACS163 and the UT54ACTS163 are synchronous
presettable 4-bit binary counters that feature internal carry lookahead logic for high-speed counting designs. Synchronous operation occurs by having all flip-flops clocked simultaneously
so that the outputs change coincident with each other when instructed by the count-enable inputs and internal gating. A buffered clock input triggers the four flip-flops on the rising (positive-going) edge of the clock input waveform.
The counters are fully programmable (i.e., they may be preset
to any number between 0 and 15). Presetting is synchronous;
applying a low level at the load input disables the counter and
causes the outputs to agree with the load data after the next clock
pulse.
The clear function is synchronous and a low level at the clear
input sets all four of the flip-flop outputs low after the next clock
pulse. This synchronous clear allows the count length to be modified by decoding the Q outputs for the maximum count desired.
The counters feature a fully independent clock circuit. Changes
at control inputs (ENP, ENT, or LOAD) that modify the operating mode have no effect on the contents of the counter until
clocking occurs. The function of the counter (whether enabled,
disabled, loading, or counting) will be dictated solely by the
conditions meeting the stable setup and hold times.
The devices are characterized over full military temperature
range of -55 C to +125 C.

DESCRIPTION
The UT54ACS164 and the UT54ACTS164 are 8-bit shift registers which feature AND-gated serial inputs and an asynchronous clear. The gated serial inputs (A and B) permit complete
control over incoming data. A low at either input inhibits entry
of new data and resets the first flip-flop to the low level at the
next clock pulse. A high-level at both serial inputs sets the first
flip-flop to the high level at the next clock pulse. Data at the
serial inputs may be changed while the clock is high or low,
providing the minimum setup time requirements are met.
Clocking occurs on the low-to-high-level transition of the clock
input.
The devices are characterized over full military temperature
range of -55 C to +125 C.

The UT54ACS165 and the UT54ACTS165 are 8-bit serial shift registers that, when clocked, shift the data toward serial output QH. Parallelin access to each stage is provided by eight individual data inputs that
are enabled by a low level at the SH/LD input. The devices feature a
clock inhibit function and a complemented serial output QH .
Clocking is accomplished by a low-to-high transition of the CLK input
while SH/LD is held high and CLK INH is held low. The functions of
the CLK and CLK INH (clock inhibit) inputs are interchangeable.
Since a low CLK input and a low-to-high transition of CLK INH will
also accomplish clocking, CLK INH should be changed to the high
level only while the CLK input is high. Parallel loading is disabled
when SH/LD is held high. Parallel inputs to the registers are enabled
while SH/LD is low independently of the levels of CLK, CLK INH or
SER inputs.
The devices are characterized over full military temperature range of
-55 C to +125 C.

DESCRIPTION
The UT54ACS169 and the UT54ACTS169 are synchronous 4bit binary counters that feature an internal carry look-ahead for
cascading in high-speed counting applications. Synchronous
operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other
when instructed by the count-enable inputs and internal gating.
Synchronous operation helps eliminate the output counting
spikes that are normally associated with asynchronous (ripple
clock) counters. The clock input triggers the four flip-flops on
the rising (positive-going) edge of the clock.
The counters are fully programmable (i.e., the outputs may each
be preset high or low). The load input circuitry allows loading
with the carry-enable output of cascaded counters. Loading is
synchronous; applying a low level at the load input disables the
counter and causes the outputs to agree with the data inputs after
the next clock pulse.
The carry look-ahead circuitry provides for cascaded counters
for n-bit synchronous application without additional gating. Instrumental in accomplishing this function are two count-enable
inputs and a carry output. Assert both count enable inputs (ENP
and ENT) to count. The direction of the count is determined by
the level of the U/D input. When U/D is high, the counter counts
up; when low, it counts down. Input ENT is fed forward to
enable the carry output. The ripple carry output

Transitions at ENP or ENT are allowed regardless of the level
of the clock input.
The counters feature a fully independent clock circuit. Changes
at control inputs (ENP, ENT, LOAD, U/D) that modify the operating mode have no effect on the contents of the counter until
clocking occurs. The function of the counter (whether enabled,
disabled, loading, or counting) will be dictated solely by the
conditions meeting the stable setup and hold times.
The devices are characterized over full military temperature
range of -55°C to +125°C.
RCO enables a low-level pulse while the count is zero (all inputs
low) counting down or maximum (15) counting up. The lowlevel overflow carry pulse can be used to enable successive cascaded stages.

The outputs of the four flip-flops are triggered on a low-to-highlevel transition of the clock input if the enable input (CTEN) is
low. A logic one applied to CTEN inhibits counting. The direction of the count is determined by the level of the down/up
(D/U) input. When D/U is low, the counter counts up and when
D/U is high, it counts down.
The counters feature a fully independent clock circuit. Changes
at control inputs (CTEN and D/U) that will modify the operating
mode have no effect on the contents of the counter until clocking
occurs.
The counters are fully programmable. The outputs may be preset to either logic level by placing a low on the load input and
entering the desired data at the data inputs. The output will
change to agree with the data inputs independently of the level
of the clock input. The asynchronous load allows counters to
be used as modulo-N dividers by simply modifying the count
length with the preset inputs.
If preset to an illegal state, the counter returns to a normal sequence in one or two counts.

Two outputs have been made available to perform the cascading
function: ripple clock and maximum/minimum (MAX/MIN)
count. The MAX/MIN output produces a high-level output
pulse with a duration approximately equal to one complete cycle
of the clock while the count is zero (all outputs low) counting
down or maximum (9) counting up.
The ripple clock output (RCO) produces a low-level output
pulse under those same conditions but only while the clock input
is low. The counters easily cascade by feeding the RCO to the
enable input of the succeeding counter if parallel clocking is
used, or to the clock input if parallel enabling is used. Use the
MAX/MIN count output to accomplish look-ahead for highspeed operation.
The devices are characterized over full military temperature
range of -55 C to +125 C.

operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other
when so instructed. Synchronous operation eliminates the output counting spikes associated with asynchronous counters.

The ripple clock output (RCO) produces a low-level output
pulse under those same conditions but only while the clock input
is low. The counters easily cascade by feeding the RCO to the
enable input of the succeeding counter if parallel clocking is
used, or to the clock input if parallel enabling is used. Use the
MAX/MIN count output to accomplish look-ahead for highspeed operation.
The devices are characterized over full military temperature
range of -55°C to +125°C.
Two outputs have been made available to perform the cascading
function: ripple clock and maximum/minimum (MAX/MIN)
count. The MAX/MIN output produces a high-level output
pulse with a duration approximately equal to one complete cycle
of the clock while the count is zero (all outputs low) counting
down or maximum (15) counting up.

DESCRIPTION
The UT54ACS193 and the UT54ACTS193 are synchronous 4bit, binary reversible up-down binary counters. Synchronous
operation is provided by having all flip-flops clocked
simultaneously so that the outputs change coincident with each
other when instructed. Synchronous operation eliminates the
output counting spikes normally associated with asynchronous
counters.
The outputs of the four flip-flops are triggered on a low-to-highlevel transition of either count input (Up or Down). The direction of the counting is determined by which count input is pulsed
while the other count input is high.
The counters are fully programmable. The outputs may be preset to either level by placing a low on the load input and entering
the desired data at the data inputs. The output will change to
agree with the data inputs independently of the count pulses.
Asynchronous loading allows the counters to be used as modulo-N dividers by simply modifying the count length with the
preset inputs.

A clear input has been provided that forces all outputs to the low
level when a high level is applied. The clear function is independent of the count and the load inputs.
The counter is designed for efficient cascading without the need
for external circuitry. The borrow output (BO) produces a lowlevel pulse while the count is zero and the down input is low.
Similarly, the carry output (CO) produces a low-level pulse
while the count is maximum

DESCRIPTION
The UT54ACTS220 is designed to be a companion chip to
UTMC’s UT69151 SμMMIT family for the purpose of generating clock and wait-state signals. The device contains a divide
by two circuit that accepts TTL input levels and drives CMOS
output buffers. The chip accepts a 48MHz clock and generates
a 24MHz clock. The 48MHz clock can have a duty cycle that
varies by ± 20%. The UT54ACT220 generates a 24MHz clock
with a ± 5% duty cycle variation. The wait-state circuit generates
a single wait-state by delaying the falling edge of DTACK into
the SμMMIT. The clock/timing device generates DTACK from
the falling edge of input RCS which is synchronized by the
falling edge of 24MHz. The SμMMIT drives inputs RCS and
DMACK.
The devices are characterized over full military temperature
range of -55°C to +125°C.

24MHz
24MHz Clock. This output runs at half the frequency of the 48MHz input. The falling
edge of 24MHz is the signal that latches the DTACK outputs. 24MHz is forced high
whenever MRST is low. Properly loaded, 24MHz will have a 50% duty cycle ± 5%.
DMA Acknowledge. This input is generated by the SμMMIT. When high, this signal will
cause DTACK output to be forced high.
RAM Chip Select. This input is generated by the SμMMIT.
FUNCTIONAL TIMING: Single SμMMIT Wait-State
For both read and write memory cycles, DTACK is an input to the SμMMIT E and SμMMIT LXE/DXE. A non-wait state memory requires two clock cycles, T1 and T2 of figure 1. For accessing slower memory devices, the UT54ACTS220 holds DTACK to
a logical “1”. This results in the stretching of memory cycles by one clock to three clock cycles, TW of figure 1. The SμMMIT E
and SμMMIT LXE/DXE samples the DTACK on the rising edge of the 24 MHz clock. If DTACK is not generated before the rising edge of the clock, the SμMMIT E and SμMMIT LXE/DXE extends the memory cycle.

DESCRIPTION
The UT54ACS245 and the UT54ACTS245 are non-inverting
octal bus transceivers designed for asynchronous two-way communication between data buses. The control function implementation minimizes external timing requirements.
The devices allow data transmission from the A bus to the B bus
or from the B bus to the A bus depending upon the logic level
at the direction control (DIR) input. The enable input (G) disables the device so that the buses are effectively isolated.
The devices are characterized over full military temperature
range of -55 C to +125 C.

DESCRIPTION
The UT54ACS253 and the UT54ACTS253 are 1-line to 4-line
multiplexers that contain drivers to supply full binary decoding.
Separate output control inputs are provided for each of the two
four-line sections.
Use the three-state outputs to drive data lines in bus-organized
systems. With all but one of the common outputs disabled the
low-impedance of the single enable output will drive the bus
line to a high or low logic level. Each output has its own strobe
(G).
The devices are characterized over full military temperature
range of -55 C to +125 C.

The UT54ACS264 and the UT54ACTS264 are look-ahead generators designed specifically to perform a carry-anticipate
across any number of n-bit counters, thus increasing system
clock frequency. A carry enable CE, and carry outputs RCOA
and RCOB are provided for n-bit cascading.
Use the counter with either active-high-carry or active-low-carry counters. For active-high-carry counters, CE is active high,
the A set of inputs and output RCOA are used. The B set of
inputs are connected to a low logic level. For active-low-carry
counters, CE is active low, the B set of inputs and output RCOB
are used. The A set of inputs are connected to a high logic level.

DESCRIPTION
The UT54ACS273 and the UT54ACTS273 are positive-edgetriggered D-type flip-flops with a direct clear input.
Information at the D inputs meeting the setup time requirements
is transferred to the Q outputs on the positive-going edge of the
clock pulse. When the clock input is at either the high or low
level, the D input signal has no effect at the output.
The devices are characterized over full military temperature
range of -55 C to +125 C.

The UT54ACS279 and the UT54ACTS279 contain four basic
S-R flip-flop latches. Under conventional operation, the S-R
inputs are normally held high. When the S input is pulsed low,
the Q output will be set high. When R is pulsed low, the Q
output will be reset low. If the S-R inputs are taken low simultaneously, the Q output is unpredictable.
The devices are characterized over full military temperature
range of -55 C to +125 C.

DESCRIPTION
20-Lead Flatpack
Top View
The UT54ACS373 and the UT54ACTS373 are 8-bit latches
with three-state outputs designed for driving highly capacitive
or relatively low-impedance loads. The device is suitable for
buffer registers, I/O ports, and bidirectional bus drivers.
The eight latches are transparent D latches. While the enable
(C) is high the Q outputs will follow the data (D) inputs. When
the enable is taken low, the Q outputs will be latched at the levels
that were set up at the D inputs.
An output-control input (OC) places the eight outputs in either
a normal logic state (high or low logic levels) or a high-impedance state. The high-impedance third state and increased drive
provide the capability to drive the bus line in a bus-organized
system without need for interface or pull-up components.
The output control OC does not affect the internal operations of
the latches. Old data can be retained or new data can be entered
while the outputs are off.
The devices are characterized over full military temperature
range of -55 C to +125 C.

DESCRIPTION
20-Lead Flatpack
Top View
The UT54ACS374 and the UT54ACTS374 are non-inverting
octal D type flip-flops with three-state outputs designed for driving highly capacitive or relatively low-impedance loads. The
device is suitable for buffer registers, I/O ports, and bidirectional
bus drivers.
The eight flip-flops are edge triggered D-type flip-flops. On the
positive transition of the clock the Q outputs will follow the data
(D) inputs.
An output-control input (OC) places the eight outputs in either
a normal logic state (high or low logic level) or a high-impedance state. The high-impedance third state and increased drive
provide the capability to drive the bus line in a bus-organized
system without the need for interface or pull-up components.
The output control OC does not affect the internal operations of
the flip-flops. Old data can be retained or new data can be
entered while the outputs are off.

Notes:
1. Functional tests are conducted in accordance with MIL-STD-883 with the following input test conditions: V IH = VIH (min) + 20%, - 0%; VIL = VIL(max) + 0%,
- 50%, as specified herein, for TTL, CMOS, or Schmitt compatible inputs. Devices may be tested using any input voltage within the above specified range, but
are guaranteed to VIH(min) and VIL(max).
2. Supplied as a design limit but not guaranteed or tested.
3. Per MIL-PRF-38535, for current density 5.0E5 amps/cm2, the maximum product of load capacitance (per output buffer) times frequency should not exceed
3,765 pF/MHz.
4. Not more than one output may be shorted at a time for maximum duration of one second.
5. Capacitance measured for initial qualification and when design changes may affect the value. Capacitance is measured between the designated terminal and VSS
at frequency of 1MHz and a signal amplitude of 50mV rms maximum.
6. Maximum allowable relative shift equals 50mV.
7. All specifications valid for radiation dose 1E6 rads(Si).
8. Power does not include power contribution of any TTL output sink current.
9. Power dissipation specified per switching output.
10. This value is guaranteed based on characterization data, but not tested.
