Quad 2-input Positive-NAND Buffers With Open Collector Outputs

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.
