SN74LS03NSR TI Logic Gates | 14-SO | Quad 2-Input NAND, Open-Collector

Product Overview

The SN74LS03NSR is a quad 2-input positive-NAND gate with open-collector outputs, manufactured by Texas Instruments (TI). It belongs to the 74LS family of low-power Schottky logic devices. The open-collector outputs allow wired-AND connections and drive higher voltage or current loads. Housed in a 14-pin SOIC package (NSR suffix), it is suitable for surface-mount applications requiring compact design and reliable performance.
