74LS38 DIP Quad 2-Input NAND Buffer Open Collector IC (14-Pin TTL Logic IC)

The 74LS38 DIP Quad 2-Input NAND Buffer Open Collector IC is a TTL logic integrated circuit that contains four independent 2-input NAND buffer gates with open collector outputs in a 14-pin Dual Inline Package (DIP). Built using Low Power Schottky (LS) TTL technology, it is designed for high-voltage interfacing, signal buffering, and external load driving.

The open collector buffered outputs require external pull-up resistors and provide improved drive capability for switching higher voltage loads. The 74LS38 is widely used in relay drivers, lamp control, wired-OR logic, industrial automation, bus systems, and embedded digital applications.
