description/ordering information  
The SN74HC138 is designed to be used in 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 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 decoders is negligible.  
The conditions at the binary-select inputs at the three enable inputs select one of eight output lines. Two  
active-low and one active-high enable inputs 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.
