Description
74193 – Synchronous 4-Bit Binary Counter with Dual Clock
General Description
The 74193 circuit is a synchronous up/down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously, so that the outputs change together when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (rippleclock) counters.
Features
■ Fully independent clear input
■ Synchronous operation
■ Cascading circuitry provided internally
■ Individual preset each flip-flop
