SYNCHRONOUS  
PRESETTABLE  
BINARY COUNTER  
The MC74AC161/74ACT161 and MC74AC163/74ACT163 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 MC74AC161/74ACT161 has an asynchronous Master Reset input  
that overrides all other inputs and forces the outputs LOW. The MC74AC163/  
74ACT163 has a Synchronous Reset input that overrides counting and parallel  
loading and allows the outputs to be simultaneously reset on the rising edge of  
the clock.
