2μ CMOS - Latchup immune ‰ High speed ‰ Low power consumption ‰ Single 5 volt supply ‰ Available QML Q or V processes ‰ Flexible package - 16-pin DIP - 16-lead flatpack ‰ UT54ACS191 - SMD 5962-96564 ‰ UT54ACTS191 - SMD 5962-96565 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.
The outputs of the four flip-flops are triggered on a low-to-highlevel transition...
