Overview
MC54/74F132 QUAD 2-INPUT NAND SCHMITT TRIGGER The MC54/74F132 contains four 2-input NAND gates which accept standard TTL input signals and provide standard TTL output levels.
They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
In addition, they have greater noise margin than conventional NAND gates.
Each circuit contains a 2-input Schmitt trigger followed by a Darlington level shifter and a phase splitter driving a TTL totem-pole output.
The Schmitt trigger uses positive feedback to effectively speed up slow input transitions and provide different input threshold voltages for positive and negative-going transitions.
This hysteresis between the positive-going and negative-going input threshold (typically 800 mV) is determined by resistor ratios and is essentially insensitive to temperature and supply voltage variations.
