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.
