description
The ′ALS139 are dual 2-line to 4-line
decoders/demultiplexers designed for use in
high-performance memory-decoding or datarouting 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
NC – No internal connection
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.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
