74AC161 74ACT161  
Synchronous Presettable Binary Counter  
General Description  
Features  
The AC/ACT161 are high-speed synchronous modulo-16  
binary counters. They are synchronously presettable for  
application in programmable dividers and have two types  
of Count Enable inputs plus a Terminal Count output for  
versatility in forming synchronous multistage counters. The  
AC/ACT161 has an asynchronous Master Reset input that  
overrides all other inputs and forces the outputs LOW.  
ICC reduced by 50%  
Synchronous counting and loading  
High-speed synchronous expansion  
Typical count rate of 125 MHz  
Outputs source/sink 24 mA  
ACT161 has TTL-compatible inputs
