HEX SCHMITT-TRIGGER INVERTER

these schmitt-trigger devices contain six independent inverters. they perform the boolean function y = a\. because of the schmitt action they have different input threshold levels for positive-going (vt+) and for negative-going (vt) signals. these circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean jitter-free output signals. they also have a greater noise margin than conventional inverters.
