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.
