General description
The 74LVC3G34 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.
The inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device as translator in a mixed 3.3 V and 5 V environment.
This device is fully specified for partial power-down applications using Ioff. The Ioff circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
The 74LVC3G34 provides three buffers.

Features
■ Wide supply voltage range from 1.65 V to 5.5 V
