... 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 hav- ing 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 (ripple- clock) counters ...
