MC74ACT161 Datasheet (ON Semiconductor) - Synchronous Presettable Binary Counter

MC74ACT161, Synchronous Presettable Binary Counter

MC74AC161, MC74ACT161, MC74AC163, MC74ACT163 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 input
