U74AHC1G132
CMOS IC
SINGLE 2-INPUT NAND GATE
WITH SCHMITT-TRIGGER
INPUTS

DESCRIPTION
The U74AHC1G132 contains one 2-input NAND gate with
Schmitt-trigger inputs designed for 2V to 5.5V VCC operation and
performs the Boolean function Y = A‧B or Y = A + B in
positive logic.
Because of Schmitt action, this device has different input
threshold levels for positive-going (VT+) and negative-going (VT-)
signals.
This device can be triggered from the slowest of input ramps
and still give clean jitter-free output signals.

FEATURES
* Operation voltage range: 2 ~ 5.5V
* Max tPd of 7.7 ns at 5 V
* Low static power consumption; ICC=2μA (Max.)
* ±8mA output drive at 5 V

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
