DESCRIPTION
PIN CONNECTIONS (top view)
The M54/74HC40102/40103 are high speed CMOS
8-STAGE PRESETTABLE
SYNCHRONOUS
DOWN COUNTERS fabricated with silicon gate
2
C MOS technology. They achieve the high speed
operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
The HC40102, and HC40103 consist of an 8-stage
synchronous down counter with a single output
which is active when the internal count is zero. The
HC40102 is configured as two cascaded 4-bit BCD
counters, and the HC40103 contains a single 8-bit
binary counter. Each type has control inputs for enabling or disabling the clock, for clearing the counter
to its maximum count, and for presetting the counter
either synchronously or asynchronously. All control
inputs and the CARRY-OUT/ZERO-DETECT output are active-low logic. In normal operation, the
counter is decremented by one count on each positive transition of the CLOCK. Counting is inhibited
when the CARRY-IN/COUNTER ENABLE (CI/CE)
input is high. The CARRY-OUT/ZERO-DETECT
(CO/ZD) output goes low when the count reaches
zero if the CI/CE input is low, and remains low for
one full clock period. When the SYNCHRONOUS
PRESET-ENABLE (SPE) input is low, data at the J
input is clocked into the counter on the next positive
clock transition regardless of the state of the CI/CE
input.

DESCRIPTION (Continued)
When the ASYNCHRONOUS PRESET-ENABLE
(APE) input is low, data at the J inputs is asynchronously forced into the counter regardless of the state
of the SPE, CI/CE, or CLOCK inputs. J Inputs J0-J7
represent two 4-bit BCD words for the HC40102 and
a single 8-bit binary word for the HC40103. When
the CLEAR (CLR input is low, the counter is asynchronously cleared to its maximum count (9910 for
the HC40102 and 25510 for the HC40103 regardless of the state of any other input. The precedence
relationship between control input is indicated in the
truth table. If all control inputs are high at the time of
zero count, the counters will jump to the maximum
count, giving a counting sequence of 100 pr 256
clock pulses long. The HC40102 and HC40103 may
be cascaded using the CI/CE input and the CO/ZD
output, in either a synchronous or ripple mode. All
inputs are equipped with protection circuits against
static discharge and transient excess voltage.

M54/M74HC40102/40103
FUNCTIONAL DESCRIPTION
The HC40102 and HC40103 are 8-stage presettable synchronous down counters. Carry Out/Zero
Detect (CO/ZD) is output at the ”L” level for the
period of 1 bit when the readout becomes ”0”. The
HC40102 adopts binary coded decimal notation,
making setting up to 99 counts possible. While the
HC40103 adopts 8-bit binary counter and can set up
to 255 counts.
COUNT OPERATION
At the ”H” level of control input of CLEAR, SPE and
APE, the counter carriers out down count operation
one by one at the rise of pulse given to CLOCK input.
Count operation can be inhibited by setting Carry
Input/Clock Enable CI/CE to the ”H” level.
CO/ZD is output at the ”L” level when the readout
becomes ”0” but is not output even if the readout
becomes ”0” when CI/CE is at the ”H” level, thus
maintaining the ”H” level.
Synchronous cascade operation can be carried out
by using CI/CE input and CO/ZD output.
The contents of count jump to maximum count (99
for the HC40102 and 225 for the HC40103) if clock
is given when the readout is ”0”. Therefore, operation of 100-frequency division and that of 256-frequency division are carried out for the HC40102 and
HC40103, respectively, when clock input alone is
given without various kinds of preset operation.
PRESET OPERATION AND RESET OPERATION
When Clear (CLEAR) input is set to the ”L” level, the
readout is set to the maximum count independetly
of other inputs. When Asynchronous Preset Enable
(APE) input is set to the ”L” level, readouts given on
J0 to J7 can be preset asynchronously to counter independently of inputs other than CLEAR input.
When Synchronous Preset Enable (SPE) is set to
the ”L” level, the readouts given on J0 to J7 can be
preset to counter synchronously with the rise of
clock.
As to these operation modes, refer to the truth table.

PARALLEL CARRY CASCADING
* At synchronous cascade connection, huzzerd occurs at C0 output after its second stage when digitplace changes, due to delay arrival. Therefore,
take gate from HC32 or the like, not from C0 output at the rear stage directly.
PROGRAMMABLE TIMER
Note :The above formula does not take into account the phase of clock input. Therefore, the real pulse width is the distance between the
