This SN74LVC1G139 2-to-4 line decoder is designed for 1.65-V to 5.5-V
The SN74LVC1G139 2-line to 4-line decoder is designed to be used in high-performance
memory-decoding 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.
