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.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
