MM74HC161 • MM74HC163

Synchronous Binary Counter with Asynchronous Clear

• Synchronous Binary Counter with Synchronous Clear

The MM74HC161 counter is cleared asynchronously.

When the CLEAR is taken LOW the counter is cleared

immediately regardless of the CLOCK.

General Description

The MM74HC161 and MM74HC163 synchronous presetta-

ble counters utilize advanced silicon-gate CMOS technol-

Two active HIGH enable inputs (ENP and ENT) and a RIP-

ogy and internal look-ahead carry logic for use in high

PLE CARRY (RC) output are provided to enable easy cas-

speed counting applications. They offer the high noise

cading of counters. Both ENABLE inputs must be HIGH to

immunity and low power consumption inherent to CMOS

count. The ENT input also enables the RC output. When

with speeds similar to low power Schottky TTL. The HC161

enabled, the RC outputs a positive pulse when the counter

and the HC163 are 4 bit binary counters. All flip-flops are

overflows. This pulse is approximately equal in duration to

clocked simultaneously on the LOW-to-HIGH transition

the HIGH level portion of the Q_Aoutput. The RC output is

(positive edge) of the CLOCK input waveform.

fed to successive cascaded stages to facilitate easy imple-

mentation of N-bit counters.

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

taken HIGH before the positive edge of CLOCK the count
