SN54ALS139, SN74ALS139 DUAL 2-LINE TO 4-LINE DECODERS/DEMULTIPLEXERS SDAS204A – APRIL 1982 – REVISED DECEMBER 1994 • • • SN54ALS139 . . . J PACKAGE SN74ALS139 . . . D OR N PACKAGE (TOP VIEW) Designed Specifically for High-Speed Memory Decoders and Data Transmission Systems Incorporate Two Enable Inputs to Simplify Cascading and /or Data Reception Package Options Include Plastic Small-Outline (D) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs 1G 1A 1B 1Y0 1Y1 1Y2 1Y3 GND 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. 1 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 VCC 2G 2A 2B 2Y0 2Y1 2Y2 2Y3 1A 1G NC VCC 2G SN54ALS139 . . .

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.
