Overview
The 74HC4040DB,112-NEX, produced by Nexperia USA Inc., is a 12-stage binary ripple counter. This component 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 to enable the use of current limiting resistors for interfacing with voltages in excess of VCC.
