description/ordering information  
The ’HC138 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  
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. This means that the effective system  
delay introduced by the decoders is negligible.
