description  
The ALS138A and AS138 are 3-line to 8-line  
decoders/demultiplexers designed for high-  
performance memory-decoding or data-routing  
applications requiring very short propagation  
delay times. In high-performance systems, these  
devices can be used to minimize the effects of  
system decoding. When employed with  
high-speed memories with a fast enable circuit,  
thedelaytimesofthedecoderandtheenabletime  
of the memory are usually less than the typical  
access time of the memory. The effective system  
delayintroducedbytheSchottky-clampedsystem  
decoder is negligible.

The conditions at the binary-select (A, B, and C)  
inputs and the three enable (G1, G2A, and G2B)  
inputs select one of eight output lines. Two  
active-low and one active-high enable inputs  
NC – No internal connection  
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.  
The SN54ALS138A and SN54AS138 are characterized for operation over the full military temperature range  
of 55°C to 125°C. The SN74ALS138A and SN74AS138 are characterized for operation from 0°C to 70°C.
