Product Overview
The SN74LS38D is a quad 2-input positive-NAND gate with open-collector outputs, manufactured by Texas Instruments. It is part of the 74LS family, offering low power consumption and high speed. The device is housed in a 14-pin SOIC package, suitable for surface-mount applications. Each gate performs the Boolean function Y = A·B in positive logic. The open-collector outputs allow wired-AND connections and can drive higher voltage or current loads when used with external pull-up resistors.
