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.
