DESCRIPTION/ORDERING INFORMATION  
The SN74LV138AT is a 3-line to 8-line decoder/demultiplexer, designed for high-performance memory-decoding  
or data-routing applications requiring 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 the 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.
