MM74HC161 • MM74HC163 Synchronous Binary Counter with Asynchronous Clear • Synchronous Binary
Counter with Synchronous Clear
September 1983
Revised December 2003
MM74HC161 • MM74HC163
Synchronous Binary Counter with Asynchronous Clear
• Synchronous Binary Counter with Synchronous Clear
General Description
The MM74HC161 and MM74HC163 synchronous presetta-
ble counters utilize advanced silicon-gate CMOS technol-
ogy and internal look-ahead carry logic for use in high
speed counting applications. They offer the high noise
immunity and low power consumption inherent to CMOS
with speeds similar to low power Schottky TTL. The HC161
and the HC163 are 4 bit binary counters. All flip-flops are
clocked simultaneously on the LOW-to-HIGH transition
(positive edge) of the CLOCK input waveform.
These counters may be preset using the LOAD input. Pre-
setting of all four flip-flops is synchronous to the rising edge
of CLOCK. When LOAD is held LOW counting is disabled
and the data on the A, B, C, and D inputs is loaded into the
counter on the rising edge of CLOCK. If the load input is
taken HIGH before the positive edge of CLOCK the count
operation will be unaffected.
All of these counters may be cleared by utilizing the
CLEAR input. The clear function on the MM74HC163
counter is synchronous to the clock. That is, the counters
are cleared on the positive edge of CLOCK while the clear
input is held LOW.
The MM74HC161 counter is cleared asynchronously.
When the CLEAR is taken LOW the counter is cleared
immediately regardless of the CLOCK.
Two active HIGH enable inputs (ENP and ENT) and a RIP-
PLE CARRY (RC) output are provided to enable easy cas-
cading of counters. Both ENABLE inputs must be HIGH to
count. The ENT input also enables the RC output. When
enabled, the RC outputs a positive pulse when the counter
overflows. This pulse is approximately equal in duration to
the HIGH level portion of the Q
A
output. The RC output is
fed to successive cascaded stages to facilitate easy imple-
mentation of N-bit counters.
All inputs are protected from damage due to static dis-
charge by diodes to V
CC
and ground.

Note 5:
For a power supply of 5V
±
10% the worst case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4.5V values should be used when
designing with this supply. Worst case V
IH
and V
IL
occur at V
CC
=
5.5V and 4.5V respectively. (The V
IH
value at 5.5V is 3.85V.) The worst case leakage cur-
rent (I
IN
, I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so the 6.0V values should be used.
