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.
