Overview
The 74HC4020D,653 is a 14-stage binary ripple counter produced by Nexperia (formerly part of NXP Semiconductors). This integrated circuit is designed for high-speed applications and is part of the 74HC logic family. It features a clock input (CP) and an overriding asynchronous master reset input (MR), along with twelve fully 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.
