QUAD 2-INPUT NAND
SCHMITT TRIGGER
The MC54/74F132 contains four 2-input NAND gates which accept stan-
dard TTL input signals and provide standard TTL output levels. They are ca-
pable of transforming slowly changing input signals into sharply defined, jit-
ter-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 trig-
ger uses positive feedback to effectively speed up slow input transitions and
provide different input threshold voltages for positive and negative-going tran-
sitions. 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.
