Quad 2-input NAND Schmitt trigger
74F132
DESCRIPTION
The 74F132 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
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
Scmitt 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 (typically 800mV)
is determined by resistor ratios and is essentially insensitive to
temperature and supply voltage variations. As long as three inputs
remain at a more positive voltage than V
T+MAX
, the gate will
respond in the transition of the other input as shown in Waveform 1.

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
CC
= 5V, T
amb
= 25°C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
