The SN74HC21DR is a dual 4-input AND gate integrated circuit manufactured by Texas Instruments. Each of the two independent gates performs the Boolean function Y = A • B • C • D in positive logic. This device is part of the HC (High-speed CMOS) technology family, offering a balance of speed and low power consumption.
Key electrical characteristics include a wide operating voltage range from 2V to 6V and a maximum propagation delay of 19ns at 6V and 50pF. The output current is rated at 5.2mA for both high and low states. Input logic levels are specified between 1.5V and 4.2V.
The SN74HC21DR is supplied in a 14-pin SOIC package, designed for surface mounting. It operates across a temperature range of -40°C to 85°C, making it suitable for various industrial and commercial applications. The device features buffered inputs and supports a significant power reduction compared to older LSTTL logic ICs.
This component is ideal for digital logic applications requiring reliable AND gate functionality. Its dual-gate design allows for implementation of two independent logic functions within a single package, contributing to board space savings and design simplification.
