M74HC4020B1R ST Counter IC | 16-DIP | 14-Stage, Binary Ripple

Product Overview

The M74HC4020B1R is a high-speed CMOS 14-stage binary ripple counter manufactured by STMicroelectronics. It is designed for general-purpose counting and frequency division applications. The device operates from a 2V to 6V supply voltage and features a master reset input to clear the counter. The 14-stage counter advances on the negative-going edge of the clock input. The M74HC4020B1R is offered in a 16-pin DIP package, making it suitable for through-hole PCB assembly.
