74HCT4020 datasheet



The 74HC4020, 74HCT4020 are high-speed Si-gate CMOS devices and are pin compatible with the “4020” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.

The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP.  Each counter stage is a static toggle flip-flop.


1. Wide supply voltage range from 2.0 V to 6.0 V

2. Multiple package options

3. Complies with JEDEC standard no. 7A


1. Frequency dividing circuits

2. Time delay circuits
