Overview
The MC74HC4040ADR2G is a 12-stage binary ripple counter produced by onsemi. This device is part of the high-performance silicon-gate CMOS family and is known for its compatibility with various logic families. It features 12 master-slave flip-flops, where the output of each flip-flop feeds the next, resulting in a frequency division by 2 at each stage. The counter advances on the negative-going edge of the clock input and has an asynchronous active-high reset. This component is widely used in applications requiring frequency division and timing functions.
