MM74HC161 • MM74HC163 Synchronous Binary Counter with Asynchronous Clear • Synchronous Binary Counter with Synchronous Clear September 1983 Revised February 1999 MM74HC161 • MM74HC163 Synchronous Binary Counter with Asynchronous Clear • Synchronous Binary Counter with Synchronous Clear General Description The MM74HC161 and MM74HC163 synchronous presettable counters utilize advanced silicon-gate CMOS technology 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.
