SN74HC20D Description

Short technical summary and product information.

The SN74HC20D is a dual 4-input NAND gate integrated circuit manufactured by Texas Instruments. This component contains two independent 4-input NAND gates, each performing the Boolean function Y = A ● B ● C ● D in positive logic. It features buffered inputs and operates across a wide voltage range from 2V to 6V, making it versatile for different circuit designs.

 

The device is housed in a 14-SOIC package with surface mount mounting type. It has a wide operating temperature range of -40°C to +85°C, ensuring reliable performance in various environmental conditions. The SN74HC20D supports fanout up to 10 LSTTL loads and offers significant power reduction compared to LSTTL logic ICs. Its typical applications include alarm/tamper detection circuits and S-R latches.

 

Key electrical characteristics include an operating voltage range of 2V to 6V and a current draw of 5.2mA. The maximum propagation delay is specified at 19ns at 6V with a 50pF load capacitance. The input logic levels range from 1.5V to 4.2V. The SN74HC20D is designed for general-purpose digital logic applications where NAND functionality is required.
