UT54ACTS191 Synchronous 4-Bit Up-Down Binary Counters

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.

UT54ACTS191 Features

* Single down/up count control line Look-ahead circuitry enhances speed of cascaded counters Fully synchronous in count modes Asynchronously presettable with load control 1.2μ CMOS - Latchup immune High speed Low power consumption Single 5 volt supply Available QML Q or V processes
