description

The SN54ALS137A, SN74ALS137A, and SN74AS137 are 3-line to 8-line decoders/ demultiplexers with latches on the three address inputs. When the latch-enable (LE ) input is low, the devices act as decoders/demultiplexers. When LE goes from low to high, the address present at the select (A, B, and C) inputs is stored in the latches. Further address changes are ignored as long as LE remains high. The output-enable controls (G1 and G2) control the outputs independently of the select or latch-enable inputs. All of the outputs are forced high if G1 is low or G2 is high. These devices are ideally suited for implementing glitch-free decoders in strobed (stored-address) applications in bus-oriented systems. The SN54ALS137A is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74ALS137A and SN74AS137 are characterized for operation from 0°C to 70°C.

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.
