Overview
The 74HC4024DB,112 is a 7-stage binary ripple counter produced by NXP USA Inc. This integrated circuit is part of the 74HC family, known for its low-power consumption and high reliability. The counter features a clock input (CP) and an overriding asynchronous master reset input (MR), along with seven fully buffered parallel outputs (Q0 to Q6). It is designed to advance 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, regardless of the clock state.
