Overview
The HEF4020BT-Q100118 is a 14-stage binary ripple counter produced by NXP USA Inc., now part of Nexperia. This integrated circuit is designed to provide a robust and reliable counting solution in various electronic systems. It features a clock input (CP) and an overriding asynchronous master reset input (MR), along with 12 buffered parallel outputs (Q0, and Q3 to Q13). The counter advances on the HIGH-to-LOW transition of the clock input, and a HIGH on the master reset input clears all counter stages and forces all outputs LOW, independent of the clock input state.
