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.
