description/ordering information  
The ’ACT139 devices are dual 2-line to 4-line decoders/demultiplexers designed for 4.5-V to 5.5-V V  
CC  
operation. These devices are designed to be used in high-performance memory-decoding or data-routing  
applications requiring very short propagation delay times. In high-performance memory systems, these  
decoders can be used to minimize the effects of system decoding. When used with high-speed memories  
utilizing a fast enable circuit, the delay times of these decoders and the enable time of the memory usually are  
less than the typical access time of the memory. This means that the effective system delay introduced by the  
decoders is negligible.  
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.
