description
These
devices
contain
four
independent
Exclusive-NOR
gates
with
open-collector
outputs. They perform the Boolean functions
Y = A
⊕ B = (A+B) (A+B) in positive logic.
A common application is a true/complement
element. If one of the inputs is high, the other input
will be reproduced in true form at the output. If one
of the inputs is low, the signal on the other input will
be reproduced inverted at the output.
The
SN54ALS811
and
SN54AS811
are
characterized for operation over the full military
temperature range of – 55
°C to 125°C. The
SN74ALS811 and SN74AS811 are characterized
for operation from 0
°C to 70°C.
