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 = A
S
B 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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
