74AC Series 2 to 6 V Synchronous Presettable Binary Counter - SOIC-16

MC74AC161DG 4-STAGE BINARY COUNTER, UP COUNTER, 2 - 6 V, 16-PIN SOIC

COUNTER, SYNC PRESETTABLE BINARY, SOIC16; Logic Family / Base Number: 74AC161; Counter Type: Presettable Binary, Synchronous; Clock Frequency: 167MHz; Count Maximum: 15; Logic Case Style; Available until stocks are exhausted

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.
