74193 Binary counter (0 to 15

74LS193 TTL 74LS193 Integrated Circuit Designed as a 4-bit up/down binary counter. It is a binary counter top / bottom of module 16. Separates and counts back and forth clocks. The SN74LS193N is a 4-bit up/down synchronous circuit with the dual and clear clock. This circuit is synchronous reversible counter monolithic having a complexity of 55 equivalent doors. Synchronous operation It is provided by having all the flip-flops synchronized simultaneously, so that the outputs change coincidentally with each other when indicated by the address logic. This mode of operation eliminates the output count spikes that are normally associated with the asynchronous counter. The outputs of the four master-slave flip-flops are caused by a low to high level transition, either count input. The counting address is determined by input count which is pressed while the other count input is high. An erase input has been provided forcing all outputs to the low level when a high level is applied. The erase function is independent of the counting and charging inputs. Clear entries, counting and loading are temporarily stored to reduce unit requirements.
