SN74HC4020NSR TI 14-Stage Binary Counter | 16-SO | 2V-6V, 24MHz

Product Overview

The SN74HC4020NSR from Texas Instruments is a high-speed 14-stage binary ripple counter fabricated using advanced silicon-gate CMOS technology. It operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The device features a master reset input that clears all stages to a low level, and a clock input with Schmitt-trigger action for slow or noisy clock signals. The counter advances on the negative-going edge of the clock pulse. All inputs and outputs are fully compatible with TTL levels when using a 5V supply.
