CD54HCT4020 - 14-Stage Binary Counter
The ’HC4020 and ’HCT4020 are 14-stage ripple-carry binary counters.
All counter stages are controller/ peripheral flip- flops.
The state of the stage advances one count on the negative clock transition of each input pulse; a high voltage level on the MR line resets all counters to their zero state.
