Overview
The 74HC4040D,652 is a 12-stage binary ripple counter produced by Nexperia USA Inc. This integrated circuit is part of the 74HC family, known for its high noise immunity and low power dissipation. The counter features a clock input (CP) and an overriding asynchronous master reset input (MR), along with twelve parallel outputs (Q0 to Q11). It advances on the HIGH-to-LOW transition of the clock input and can be reset to zero by a HIGH signal on the master reset input, independent of the clock state.
