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. All inputs and outputs are buffered. September 1997 Features • Fully .
