description
These devices contain four independent 2-input
positive-NAND buffers with open-collector
outputs. They perform the Boolean functions
Y = A • B or Y = A + B in positive logic. The
open-collector outputs require pullup resistors to
perform correctly. These outputs may be
connected to other open-collector outputs to
implement active-low wired-OR or active-high
wired-AND functions. Open-collector devices

The SN54ALS38B is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74ALS38B is characterized for
operation from 0°C to 70°C.
