DESCRIPTION/ORDERING INFORMATION  
The SN74LVC138A 3-line to 8-line decoder/demultiplexer is designed for 2.7-V to 3.6-V VCC operation.  
The device is designed for high-performance memory-decoding or data-routing applications requiring very short  
propagation delay times. In high-performance memory systems, this decoder minimizes the effects of system  
decoding. When employed with high-speed memories utilizing a fast enable circuit, 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.  
The conditions at the binary-select inputs and the three enable inputs select one of eight output lines. Two  
active-low enable inputs and one active-high enable input reduce the need for external gates or inverters when  
expanding. A 24-line decoder can be implemented without external inverters, and a 32-line decoder requires only  
one inverter. An enable input can be used as a data input for demultiplexing applications.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in  
a mixed 3.3-V/5-V system environment.
