74HCT4040PW,112

Counter Dividers Overview

The Nexperia 74HCT4040PW,112 is a 12-stage binary ripple counter housed in a 16-pin TSSOP package. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum counting frequency of 79MHz. The device utilizes negative edge-triggered flip-flops for upward counting and features an asynchronous master reset input. Designed for surface mount technology, it functions reliably across an extended temperature range from -40°C to +125°C.
