SN74HC20DR Description

Short technical summary and product information.

The SN74HC20DR from Texas Instruments is a dual 4-input NAND gate integrated circuit. Each gate performs the Boolean function Y = A ● B ● C ● D in positive logic. This device features buffered inputs and operates across a wide voltage range of 2 V to 6 V, with a broad operating temperature range from -40°C to +85°C.

 

Designed for applications such as alarm/tamper detection circuits and S-R latches, the SN74HC20DR offers significant power reduction compared to LSTTL logic ICs. It supports a fanout of up to 10 LSTTL loads. The component is housed in a 14-pin SOIC package and utilizes surface mount technology.

 

Key electrical characteristics include a maximum propagation delay of 19ns at 6V and 50pF. The input logic levels range from 1.5V to 4.2V. This device contains two independent 4-input NAND gates, making it suitable for various digital logic designs.
