8 Detailed Description

8.1 Overview

The SN74LVC2G34 device contains two buffer gates that each perform the Boolean function Y = A. 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.

8.3 Feature Description

The SN74LVC2G34 device has a wider operating voltage range, operating from 1.65 V to 5.5 V, and allows

down voltage translation. The SN74LVC2G34 Ioff feature allows voltages on the inputs and outputs when VCC is

0 V.
