HEF4020B Datasheet (nexperia) - 14-stage binary counter

HEF4020B, 14-stage binary counter

The HEF4020B is a 14-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and 12 buffered parallel outputs (Q0, and Q3 to Q13).

The counter advances on the HIGH-to-LOW transition of CP.

A HIGH on MR clears all counter stages and forces all outputs L
