CD74HCT21MT TI Logic Gates | 14-SOIC | Dual 4-Input AND Gate, 2V to 6V

Product Overview

The CD74HCT21MT is a high-speed CMOS dual 4-input AND gate from Texas Instruments, fabricated with silicon gate technology. It features operation similar to the LSTTL family but with lower power consumption and higher noise immunity. The device contains two independent 4-input AND gates, each performing the Boolean function Y = A • B • C • D. It is designed for use in high-performance logic systems where low power dissipation and high noise immunity are required.
