description/ordering information  
The ’HC139 devices are designed for  
high-performance  
memory-decoding  
or  
data-routing applications requiring very short  
propagation delay times. In high-performance  
memory systems, these decoders can minimize  
the effects of system decoding. When employed  
with high-speed memories utilizing a fast enable  
circuit, the delay time 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.
