The SNx4HC132 device functions as a NAND gate, but because of the Schmitt action, it has
different input threshold levels for positive and negative going signals. The SNx4HC132 devices
perform the Boolean function
Y = A 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.
