Overview
The 74HC4040D-Q100118 is a 12-stage binary ripple counter produced by NXP USA Inc. This integrated circuit is part of the 74HC series and is designed to meet the stringent requirements of automotive and industrial 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. Each counter stage is a static toggle flip-flop, and the inputs include clamp diodes for interfacing with voltages beyond the supply voltage (VCC).
