SN74LS38NSR TI Logic Gates | 14-SO | Quad 2-Input NAND, Open-Collector

Product Overview

The SN74LS38NSR is a quad 2-input positive-NAND gate with open-collector outputs from Texas Instruments. It is designed for use in systems requiring high-speed logic with wired-AND capability. The device operates from a 5V supply and features Schottky-clamped transistors for improved performance. The open-collector outputs allow multiple outputs to be connected together to implement active-low wired-OR or active-high wired-AND functions. This device is ideal for driving lamps, relays, or logic lines where pull-up resistors are used.
