3 Description

The SN74LVC3G34 device is a triple buffer gate

designed for 1.65-V to 5.5-V VCC operation. The

SN74LVC3G34 device performs the Boolean function

Y = A in positive logic.

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.
