TI CD74HCT4020M96

CDx4HC4020 and CDx4HCT4020 are high-speed CMOS logic 14-stage ripple-carry binary counters. All counter stages are master/slave flip-flops; the state of the counters is advanced one count on each negative clock transition of the input pulse. A high voltage level on the MR line resets all counters to the zero state. All inputs and outputs are fully buffered. For all available packages, refer to the Orderable Products appendix at the end of the datasheet.
