SN74HC191N - 4-BIT SYNCHRONOUS UP/DOWN BINARY COUNTERS

Download the SN74HC191N datasheet PDF. This datasheet also covers the SN74HC191 variant, as both devices belong to the same 4-bit synchronous up/down binary counters family and are provided as variant models within a single manufacturer datasheet.

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.
