DESCRIPTION/ORDERING INFORMATION
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.

TOP-SIDE MARKING
(2)
Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at
www.ti.com/sc/package.
DBV/DCK: The actual top-side marking has one additional character that designates the assembly/test site.
YEA/YZA, YEP/YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one
following character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb,
•
= Pb-free).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.

DESCRIPTION/ORDERING INFORMATION (CONTINUED)
NanoStar™ and NanoFree™ 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.
The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
The value of V
CC
is provided in the recommended operating conditions table.
The package thermal impedance is calculated in accordance with JESD 51-7.
