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