UT54ACS191 Description
The UT54ACS191 and the UT54ACTS191 are synchronous 4bit 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 so instructed. Synchronous operation eliminates the output counting spikes associated with asynchronous counters.
