3 Description
This dual Schmitt-Trigger buffer is designed for 1.65-
V to 5.5-V VCC operation.
The SN74LVC2G17 device 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 (VT+) and negative-going
(VT–) signals.
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 Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow
through the device when it is powered down.
