74F132
Quad 2-Input NAND Schmitt Trigger
General Description
The F132 contains four 2-input NAND gates which accept
standard TTL input signals and provide standard TTL out-
put levels. They are capable of transforming slowly chang-
ing input signals into sharply defined, jitter-free output
signals. In addition, they have a greater noise margin than
conventional NAND gates.
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 effec-
tively 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 deter-
mined by resistor ratios and is essentially insensitive to
temperature and supply voltage variations.

Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 2:
Either voltage limit or current limit is sufficient to protect inputs.
