DM74LS193 Synchronous 4-Bit Binary Counter with Dual Clock
General Description
The DM74LS193 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.
The outputs of the four master-slave flip-flops are triggered by a LOW-to-HIGH level transition of either count (clock) input.
The direction of counting is determined by whi...
