SN74LS20DR TI Dual 4-Input NAND Gate | 14-SOIC | 4.75V-5.25V, TTL

Product Overview

The SN74LS20DR from Texas Instruments is a dual 4-input NAND gate integrated circuit, part of the 74LS family of low-power Schottky TTL devices. It is designed for use in a wide range of digital logic applications requiring high speed and low power consumption. The device is housed in a 14-pin SOIC package, making it suitable for surface-mount technology (SMT) assembly. Each gate performs the Boolean function Y = A·B·C·D in positive logic. The SN74LS20DR operates over a supply voltage range of 4.75V to 5.25V and features typical propagation delays of 15 ns, with a maximum of 22 ns. Its low power dissipation of 2 mW per gate (typical) makes it ideal for battery-powered and energy-efficient designs.
