CD74HCT4020E TI 14-Stage Binary Counter | 16-PDIP | 4.5V-5.5V, 25MHz

Product Overview

The CD74HCT4020E is a high-speed 14-stage binary ripple counter from Texas Instruments, fabricated using silicon gate CMOS technology. It operates at a supply voltage range of 4.5V to 5.5V, making it compatible with TTL logic levels. 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 rise/fall times. The counter advances on the negative-going edge of the clock pulse. All inputs are protected against electrostatic discharge.
