Overview
The 74HC4040D-Q100J, produced by Nexperia USA Inc., is a 12-stage binary ripple counter integrated circuit. This component features a clock input (CP), an overriding asynchronous master reset input (MR), and 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 to enable the use of current limiting resistors for interfacing with voltages exceeding VCC. This product is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for automotive applications.
