This decoder is designed for 1.65-V to 5.5-V VCC operation.

The SN74LVC1G29 device is a 2-of-3 decoder/demultiplexer. When the enable (G) input signal is low, only one of the outputs is in the low state, depending on the input levels of A0 and A1. When G is high, Y0, Y1, and Y2 are high, regardless of the input states.

This device is fuly specified for partial-power-down applications using Ioff. The Ioff circuitry disable 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.
