DESCRIPTION

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 fully 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.
