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. The ’HC132 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.
