Intersil CD74HCT4020M

二进制计数器14.5 V ~ 5.5 V

Overview

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.
