1. General description

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 LOW, independent of the state of CP. Each counter stage is a static toggle

flip-flop. Inputs include clamp diodes. This enables the use of current limiting resistors to interface

inputs to voltages in excess of VDD.
