CD74HCT393E - Dual 4-Stage Binary Counter
The Harris CD74HC393 and CD74HCT393 are 4-stage ripple-carry binary counters.
Al counter stages are masterslave flip-flops.
The state of the stage advances one count on the negative transition of each clock pulse; a high voltage level on the MR line resets all counters to their zero state.
