SN7438N TI Logic Gates | 14-PDIP | Quad 2-Input NAND, Open-Collector

Product Overview

The SN7438N is a quad 2-input NAND gate with open-collector outputs, manufactured by Texas Instruments. It is designed for use in systems requiring high noise immunity and low power consumption. The device operates from a 5V supply and is available in a 14-pin PDIP package. The open-collector outputs allow wired-AND connections and can drive higher voltage or current loads when used with external pull-up resistors.
