The MC74HC4024N is a high-speed silicon-gate CMOS 7-stage binary counter. It is a ripple-carry counter where each flip-flop is triggered by the output of the preceding flip-flop. The device features an asynchronous master reset (MR) input which resets all counter stages to the low level when asserted. It is characterized for operation from 2 V to 6 V.
