SN74LS03N TI Logic Gates | 14-PDIP | Quad 2-Input NAND, Open-Collector

Product Overview

The SN74LS03N is a quad 2-input positive-NAND gate with open-collector outputs from Texas Instruments. It belongs to the 74LS family of low-power Schottky TTL logic devices. The open-collector outputs allow wired-AND connections and are suitable for driving lamps, relays, or interfacing with other logic families. The device is housed in a 14-pin plastic DIP package, making it ideal for through-hole PCB designs.
