Features

Description

• Fully Static Operation

• Buffered Inputs

The ’HC4020 and ’HCT4020 are 14-stage ripple-carry

binary counters. All counter stages are master-slave 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.
