Each circuit functions as a quadruple AND gate. They perform the Boolean function Y = A ? B or Y = (A\ + B\)\ in positive logic. Because of the Schmitt action, the inputs have different input threshold levels for positive- and negative-going signals.
These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean jitter-free output signals.
