Overview
The 74HC4040DB-Q100J, produced by Nexperia USA Inc., is a 12-stage binary ripple counter integrated circuit. This component is part of the HC/UH series and is designed for use in a variety of electronic applications. It features a clock input (CP) and an overriding asynchronous master reset input (MR), along with twelve parallel outputs (Q0 to Q11). 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.
