B = A\B + AB\ in positive logic.
These devices contain four independent Exclusive-OR gates with
open-collector outputs. They perform the Boolean functions Y = A B = A\B + AB\ in positive logic.
A common application is a true/complement element. If one of the inputs is low, the other input will be reproduced in true form at the output. If one of the inputs is high, the signal on the other input will be reproduced inverted at the output.
The SN54ALS136 and SN54AS136 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS136 and SN74AS136 are characterized for operation from 0°C to 70°C.
