DUAL SCHMITT-TRIGGER INVERTER
SCES200J APRIL 1999 REVISED JUNE 2005
The SN74LVC2G14 contains two inverters and performs the Boolean function Y = A. The device functions as
two independent inverters, but because of Schmitt action, it may have different input threshold levels for
positive-going (V
T+
) and negative-going (V
T
) signals.
This device is fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
The input negative-voltage and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(3)
The value of V
CC
is provided in the recommended operating conditions table.
(4)
The package thermal impedance is calculated in accordance with JESD 51-7.
