Synchronous Presettable Binary Counter  
n Synchronous counting and loading  
General Description  
n High-speed synchronous expansion  
n Typical count rate of 125 MHz  
n Outputs source/sink 24 mA  
n ’ACT161 has TTL-compatible inputs  
n Standard Microcircuit Drawing (SMD)  
— ’AC161: 5962-89561  
The ’AC/’ACT161 are high-speed synchronous modulo-16  
binary counters. They are synchronously presettable for ap-  
plication in programmable dividers and have two types of  
Count Enable inputs plus a Terminal Count output for versa-  
tility in forming synchronous multistage counters. The ’AC/  
’ACT161 has an asynchronous Master Reset input that over-  
rides all other inputs and forces the outputs LOW.
