description
The ’LV139A devices are dual 2-line to 4-line
decoders/demultiplexers designed for 2-V to
5.5-V VCC operation.
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 are usually 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.
The SN54LV139A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74LV139A is characterized for operation from –40
°C to 85°C.
