This SN74LVC1G139 2-to-4 line decoder is designed for 1.65-V to 5.5-VVCC operation.
The SN74LVC1G139 2-line to 4-line decoder is designed to be used in high-performancememory-decoding or data-routing applications requiring very short propagation delay times. Inhigh-performance memory systems, this decoder can be used to minimize the effects of systemdecoding. When used with high-speed memories using a fast enable circuit, the delay times of thesedecoders and the enable time of the memory usually are less than the typical access time of thememory. This means that the effective system delay introduced by the decoder is negligible.
NanoStar and NanoFree package technology is a major breakthrough in device packagingconcepts, using the die as the package.
This device is fully specified for partial-power-down applications usingIoff. The Ioff circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.
