74AC11191 - SYNCHRONOUS 4-BIT UP/DOWN BINARY COUNTER

Datasheet Summary

Description

The 74AC11191 is a synchronous, 4-bit binary reversible up/down counter.

Synchronous counting operation is provided by clocking all flip-flops simultaneously so that the outputs change coincident with each other when instructed by the steering logic.
