SN74LS38DBR TI Logic Gates | 14-SSOP | Quad 2-Input NAND, Open-Collector

Product Overview

The SN74LS38DBR is a quad 2-input positive-NAND gate with open-collector outputs, manufactured by Texas Instruments (TI). It is part of the 74LS family, offering low-power Schottky technology for high-speed logic operations. The device is housed in a compact 14-pin SSOP package, making it suitable for space-constrained applications. Each gate performs the Boolean function Y = A • B in positive logic, with open-collector outputs allowing wired-AND connections and driving external loads up to 24 mA sink current. The SN74LS38DBR operates over a wide voltage range of 4.75V to 5.25V and is characterized for operation from 0°C to 70°C.
