3 Description
The SN74LVC1G57 device features configurable
multiple functions. The output state is determined by
eight patterns of 3-bit input. The user can choose the
logic functions AND, OR, NAND, NOR, XNOR,
inverter, and buffer. All inputs can be connected to
VCC or GND.
This device functions as an independent gate, but
because of Schmitt action, it may have different input
threshold levels for positive-going (VT+) and negativegoing
(VT–) signals.
This configurable multiple-function gate is designed
for 1.65-V to 5.5-V VCC operation.
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.
NanoFree™ package technology is a major
breakthrough in IC packaging concepts, using the die
as the package.
