Overview

The ’HC393 and ’HCT393 are 4-stage ripple-carry binary counters. All counter stages are controller 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.
