SNJ54HC191W - 4-BIT SYNCHRONOUS UP/DOWN BINARY COUNTERS

This page provides the datasheet information for the SNJ54HC191W, a member of the SNJ54HC191J 4-BIT SYNCHRONOUS UP/DOWN BINARY COUNTERS family.

Datasheet Summary

Description

The ’HC191 devices are 4-bit synchronous, reversible, up/down binary counters.

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