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.
