74HC/HCT4020
General description
The 74HC/HCT4020 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 74HC/HCT4020 are 14-stage binary ripple counters with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered parallel outputs (Q0, Q3 to Q13).
The counter is advanced 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.
