description/ordering information
This single Schmitt-trigger buffer is designed for 1.65-V to 5.5-V V
CC
operation.
The SN74LVC1G17 contains one buffer and performs the Boolean function Y = A. The device functions as an
independent buffer, but because of Schmitt action, it may have different input threshold levels for positive-going
(V
T+
) and negative-going (V
T-
) signals.
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.

DBV/DCK/DRL: The actual top-side marking has one additional character that designates the assembly/test site.
YEA/YEP, YZA/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).
YZV: The actual top-side marking is on two lines. Line 1 has four characters to denote year, month, day, and assembly/test site. Line 2 has two
characters which show the family and function code. Pin 1 identifier indicates solder-bump composition (1 = SnPb,
·
= Pb-free).

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 and output negative-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.
