MOTOROLA MC14526B Presettable 4-bit down counter Datasheet

 SEMICONDUCTOR TECHNICAL DATA
The MC14522B BCD counter and the MC14526B binary counter are
constructed with MOS P–channel and N–channel enhancement mode
devices in a monolithic structure.
These devices are presettable, cascadable, synchronous down counters
with a decoded “0” state output for divide–by–N applications. In single stage
applications the “0” output is applied to the Preset Enable input. The
Cascade Feedback input allows cascade divide–by–N operation with no
additional gates required. The Inhibit input allows disabling of the pulse
counting function. Inhibit may also be used as a negative edge clock.
These complementary MOS counters can be used in frequency synthesizers, phase–locked loops, and other frequency division applications requiring
low power dissipation and/or high noise immunity.
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Logic Edge–Clocked Design — Incremented on Positive Transition of
Clock or Negative Transition of Inhibit
• Asynchronous Preset Enable
• Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range

PIN ASSIGNMENT
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of
any voltage higher than maximum rated voltages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.

X = Don’t Care
NOTES:
* Output “0” is low when reset goes high only it PE and CF are low.
** Output “0” is high when reset is low, only if CF is high and count is 0000.

PIN DESCRIPTIONS
Preset Enable (Pin 3) — If Reset is low, a high level on
the Preset Enable input asynchronously loads the counter
with the programmed values on P0, P1, P2, and P3.
other than all zeroes, the “0” output is valid after the rising
edge of Preset Enable (when Cascade Feedback is high).
See the Function Table.
Inhibit (Pin 4) — A high level on the Inhibit input pre–
vents the Clock from decrementing the counter. With Clock
(pin 6) held high, Inhibit may be used as a negative edge
clock input.
Cascade Feedback (Pin 13) — If the Cascade Feedback
input is high, a high level is generated at the “0” output when
the count is all zeroes. If Cascade Feedback is low, the “0”
output depends on the Preset Enable input level. See the
Function Table.
Clock (Pin 6) — The counter decrements by one for each
rising edge of Clock. See the Function Table for level requirements on the other inputs.
Reset (Pin 10) — A high level on Reset asynchronously
forces Q0, Q1, Q2, and Q3 low and, if Cascade Feedback is
high, causes the “0” output to go high.
“0” (Pin 12) — The “0” (Zero) output issues a pulse one
clock period wide when the counter reaches terminal count
(Q0 = Q1 = Q2 = Q3 = low) if Cascade Feedback is high and
Preset Enable is low. When presetting the counter to a value
P0, P1, P2, P3 (Pins 5, 11, 14, 2) — These are the preset
data inputs. P0 is the LSB.
Q0, Q1, Q2, Q3 (Pins 7, 9, 15, 1) — These are the synchronous counter outputs. Q0 is the LSB.
VSS (Pin 8) — The most negative power supply potential.
This pin is usually ground.
VDD (Pin 16) — The most positive power supply potential.
VDD may range from 3 to 18 V with respect to VSS.

APPLICATIONS INFORMATION
Divide–By–N, Single Stage
The Inhibit pin may be used to stop pulse counting. When
this pin is taken high, decrementing is inhibited.
Figure 11 shows a single stage divide–by–N application.
The MC14522B (BCD version) can accept a number greater
than 9 and count down in binary fashion. Hence, the BCD
and binary single stage divide–by–N counters (as shown in
Figure 11) function the same.
To initialize counting a number, N is set on the parallel inputs (P0, P1, P2, and P3) and reset is taken high asynchronously. A zero is forced into the master and slave of each bit
and, at the same time, the “0” output goes high. Because
Preset Enable is tied to the “0” output, preset is enabled. Reset must be released while the Clock is high so the slaves of
each bit may receive N before the Clock goes low. When the
Clock goes low and Reset is low, the “0” output goes low (if
P0 through P3 are unequal to zero).
The counter downcounts with each rising edge of the
Clock. When the counter reaches the zero state, an output
pulse occurs on “0” which presets N. The propagation delays
from the Clock’s rising and falling edges to the “0” output’s
rising and falling edges are about equal, making the “0” output pulse approximately equal to that of the Clock pulse.

Figure 12 shows a three stage cascade application. Taking
Reset high loads N. Only the first stage’s Reset pin (least significant counter) must be taken high to cause the preset for
all stages, but all pins could be tied together, as shown.
When the first stage’s Reset pin goes high, the “0” output is
latched in a high state. Reset must be released while Clock is
high and time allowed for Preset Enable to load N into all
stages before Clock goes low.
When Preset Enable is high and Clock is low, time must be
allowed for the zero digits to propagate a Cascade Feedback
to the first non–zero stage. Worst case is from the most significant bit (M.S.B.) to the L.S.B., when the L.S.B. is equal to
one (i.e. N = 1).
After N is loaded, each stage counts down to zero with
each rising edge of Clock. When any stage reaches zero and
the leading stages (more significant bits) are zero, the “0”
output goes high and feeds back to the preceding stage.
When all stages are zero, the Preset Enable automatically
loads N while the Clock is high and the cycle is renewed.
