description/ordering information (continued)
These devices are designed for high-performance memory-decoding or data-routing applications requiring very
short propagation delay times. In high-performance memory systems, these decoders can minimize the effects
of system decoding. When employed with high-speed memories utilizing a fast enable circuit, the delay time
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 decoders is negligible.
The ’LV139A devices comprise two individual 2-line to 4-line decoders in a single package. The active-low
enable (G) input can be used as a data line in demultiplexing applications. These decoders/demultiplexers
feature fully buffered inputs, each of which represents only one normalized load to its driving circuit.
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow through the devices when they are powered down.
