MC74AC161, MC74ACT161, MC74AC163, MC74ACT163 Synchronous Presettable Binary Counter The MC74AC161/74ACT161 and MC74AC163/74ACT163 are highspeed synchronous modulo16 binary counters. They are www.onsemi.com synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count MARKING output for versatility in forming synchronous multistage counters. DIAGRAM The MC74AC161/74ACT161 has an asynchronous Master Reset 16 input that overrides all other inputs and forces the outputs LOW.
