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
often are used to generate higher VOH levels.
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.
