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 QA output. 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  
and the data on the A, B, C, and D inputs is loaded into the

charge by diodes to VCC and ground.  
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.
