3 Description

This SN74LVC1G139 2-to-4 line decoder is designed

for 1.65-V to 5.5-V VCC operation.

The SN74LVC1G139 2-line to 4-line decoder is

designed to be used in high-performance memorydecoding

or data-routing applications requiring very

short propagation delay times. In high-performance

memory systems, this decoder can be used to

minimize the effects of system decoding. When used

with high-speed memories using a fast enable circuit,

the delay times of these decoders and the enable

time of the memory usually are less than the typical

access time of the memory. This means that the

effective system delay introduced by the decoder is

negligible.

NanoStar and NanoFree package technology is a

major breakthrough in device packaging concepts,

using the die as the package.

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.
