Description
Standard Products UT54ACS169/UT54ACTS169 4-Bit Up-Down Binary Counters Datasheet November 2010 www.aeroflex.com/logic .
The UT54ACS169 and the UT54ACTS169 are synchronous 4bit binary counters that feature an internal carry look-ahead for cascading in high-speed counting.
Features
* Fully synchronous operation for counting and programming Internal look-ahead for fast counting Carry output for n-bit cascading Fully independent clock circuit 1.2μ CMOS
- Latchup immune High speed Low power consumption Single 5 volt supply Available QML Q or V processes Flexible
Applications
* Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when instructed by the count-enable inputs and internal gating. Synchronous operation helps eliminate the output counting spikes that are normally associated with
