description
These devices contain four independent 2-input NAND
buffer gates with open-collector outputs. The open-
collector outputs require pull-up 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 high VOH levels.
The SN5438, SN54LS38, and SN54S38 are
characterized for operation over the full military
temperature range of ~55°C to 125°C. The SN7438,
SN74LS38, and SN74S38 are characterized for opera-
tion from 0°C to 70°C.
