HEF4020B
14-stage binary counter
Rev. 11 — 7 December 2021
Product data sheet
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
.
