description/ordering information  
The ’AHCT138 3-line to 8-line decoders/demultiplexers are designed to be used in high-performance  
memory-decoding and data-routing applications that require very short propagation-delay times. In  
high-performance memory systems, this decoder 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 this decoder 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 decoder is negligible.
