Product data sheet

1. 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.

2. Features
