CD74HC4020E TI Counter IC | 16-PDIP | 14-Stage, 12MHz

Product Overview

The CD74HC4020E from Texas Instruments is a high-speed CMOS 14-stage binary ripple counter with a maximum clock frequency of 12 MHz. It is housed in a 16-pin PDIP package, making it suitable for through-hole PCB assembly. The device operates over a wide supply voltage range of 2V to 6V and features low power consumption typical of HC logic family. The counter advances on the negative-going edge of the clock input, and a master reset (MR) input asynchronously clears all stages to zero. The CD74HC4020E is ideal for frequency division, time delay generation, and event counting in industrial and consumer electronics.
