SN74S38D TI Logic Gates | 14-SOIC | Quad 2-Input NAND, Open-Collector

Product Overview

The SN74S38D is a high-performance quad 2-input NAND gate with open-collector outputs from Texas Instruments. It is designed for applications requiring wired-AND logic or driving high-current loads. The device operates from a 4.75V to 5.25V supply and features Schottky-clamped transistors for high speed. The open-collector outputs allow multiple outputs to be connected together to implement active-low wired-OR or active-high wired-AND functions. The SN74S38D is housed in a 14-pin SOIC package, making it suitable for space-constrained designs.
