SN74HC193 Datasheet (Texas Instruments) - 4-BIT SYNCHRONOUS UP/DOWN COUNTERS

SN74HC193, 4-BIT SYNCHRONOUS UP/DOWN COUNTERS

ordering information NC * No internal connection The ’HC193 devices are 4-bit synchronous, reversible, up/down binary counters.

Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincidentally with each other when so instructed by
