These devices contain four independent 2-input NAND buffer gates with open-collector outputs. They perform the Boolean functions or Y = A\ + B\ in positive logic.
The open-collector outputs require pullup resistors to perform correctly. They may be connected to other open-collector outputs to implement active-low wired-OR or active-high wired-AND functions. Open-collector devices are often used to generate higher VOH levels.
The SN54F38 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74F38 is characterized for operation from 0°C to 70°C.
