74F132 Quad 2-Input NAND Schmitt Trigger

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 output levels. They are capable of transforming
slowly changing 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
structure. 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 (typi-
cally 800mV) is determined by resistor ratios and is
essentially insensitive to temperature and supply voltage
variations.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
