MM74HC4040MX 12-Stage Binary Ripple Counter | High-Speed CMOS | SOIC-16 SMD

Description

The MM74HC4040MX is a high-speed, silicon-gate CMOS 12-Stage Binary Ripple Counter. The device consists of 12 master-slave flip-flops connected in a series, or “ripple,” configuration. The output of each stage advances on the negative-going transition of the preceding stage’s clock pulse, meaning the counter updates sequentially through the chain.

This IC features a buffered clock input (CP) and a common asynchronous master reset (MR) input that, when taken HIGH, clears all 12 stages to a zero state. It is an essential component for frequency division applications, digital timing, and as a pulse counter where binary representation of an input signal is required.
