Quad 2-Input NAND Schmitt Trigger
The ’F132 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 in-
put signals into sharply defined, jitter-free output signals. In
addition, they have a greater noise margin than conventional
Each circuit contains a 2-input Schmitt trigger followed by
level shifting circuitry and a standard FAST® output struc-
ture. The Schmitt trigger uses positive feedback to effectively
speed-up slow input transitions, and provide different input
threshold voltages for positive and negative-going transi-
tions. This hysteresis between the positive-going and
negative-going input threshold (typically 800 mV) is deter-
mined by resistor ratios and is essentially insensitive to tem-
perature and supply voltage variations.
