description  
The 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  
NC – No internal connection  
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.
