description
Each circuit functions as a NAND gate, but because of the Schmitt action, it has different input threshold levels
for positive- and negative-going signals. It performs the Boolean function Y = ASB or Y = A+B in positive logic.
These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give
clean jitter-free output signals.
The 74AC11132 is characterized for operation from – 40°C to 85°C.
