Dual 2-Line to 4-Line Decoders/Demultiplexers
Package Options Include PlasticSmall-Outline (D) Packages, Ceramic Chip
Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
descriptionThe ′ALS139 are dual 2-line to 4-line
decoders/demultiplexers designed for use in
high-performance memory-decoding or data-
routing applications requiring very short
propagation delay times. In high-performance
memory systems, these devices can minimize the
effects of system decoding. When employed with
high-speed memories utilizing a fast-enable
circuit, the delay times of these decoders and the
enable time of the memory are usually less than
the typical access time of the memory. Therefore,
the effective system delay introduced by the
Schottky-clamped system decoder is negligible.
The ′ALS139 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. All inputs are clamped with high-performance Schottky diodes to suppress line ringing and
simplify system design.
The SN54ALS139 is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74ALS139 is characterized for operation from 0°C to 70°C.
