† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and  functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage ratings may be exceeded provided the input current ratings are observed.

These SN74F38 devices contain four independent 2-input NAND buffer gates with open-collector outputs. They perform the Boolean functions Y =A • B or Y = A + B in positive logic.

The SN74F38 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.
