2 Description
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. All inputs and outputs
are buffered.
