DESCRIPTION  
The ’AHC139 devices are dual 2-line to 4-line decoders/demultiplexers designed for 2-V to 5.5-V VCC 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.
