Overview
The MC74HC4040ADTR2G is a 12-stage binary ripple counter produced by onsemi. This high-performance silicon-gate CMOS device is designed for a wide range of applications requiring binary counting and timing functions. It consists of 12 master-slave flip-flops, where the output of each flip-flop feeds the next, and the frequency at each output is half of that of the preceding one. The counter advances on the negative-going edge of the Clock input, and it features an asynchronous active-high reset. This component is available in a 16-pin SOIC package and is RoHS compliant, making it suitable for various electronic systems.
