74HC191, 4-BIT SYNCHRONOUS UP/DOWN BINARY COUNTERS

ordering information 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.
