3 Description
This 2-to-4 line decoder is designed for 1.65-V to
5.5-V V_CC operation.
The LVC1G139 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 IC packaging concepts, using
the die as the package.
This device is fully specified for partial-power-down
applications using I_off. The I_off circuitry disables the
outputs, preventing damaging current backflow
through the device when it is powered down.
