SN74LS193 datasheet

 

Description :

These monolithic circuits are synchronous reversible (up/down) conters having a complexity of 55 equivalent gates. The 54192 and 74LS192 circuits are BCD counters and the ‘193 and SN74LS193 are 4-bit binary counters. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincidently with each other when so instructed by the steering logic. This mode of operation eliminates the output counting spikes which are normally associated with asynchronous (ripple-clock) counters.
