74163 - Synchronous Presettable Binary Counter

General Description

The AC/ACT163 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.

74AC163 • 74ACT163 Synchronous Presettable Binary Counter November 1988 Revised February 2000 74AC163 • 74ACT163 Synchronous Presettable Binary Counter General Description The AC/ACT163 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 AC/ACT163 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.
