This dual Schmitt-trigger buffer is designed for 1.65-V to 5.5-V V
CC
operation.
The SN74LVC2G17 contains two buffers and performs the Boolean function Y = A. The device functions as two
independent buffers, but because of Schmitt action, it may have different input threshold levels for positive-going
(V
T+
) and negative-going (V
T-
) signals.

package technology is a major breakthrough in IC packaging concepts, using the
die as the package.
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.
NOTES:
1. The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The value of VCC is provided in the recommended operating conditions table.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
