DM74ALS138  
3 to 8 Line Decoder/Demultiplexer  
General Description  
Features  
These Schottky-clamped circuits are designed to be used  
in high-performance memory-decoding or data-routing  
applications, requiring very short propagation delay times.  
In high-performance memory systems these decoders can  
be used to minimize the effects of system decoding. When  
used with high-speed memories, the delay times of these  
decoders are usually less than the typical access time of  
the memory. This means that the effective system delay  
introduced by the decoder is negligible.  
Designed specifically for high speed:  
Memory decoders  
Data transmission systems  
3- to 8-line decoder incorporates 3 enable inputs to sim-  
plify cascading and/or data reception  
Low power dissipation…23 mW typ  
Switching specifications guaranteed over full tempera-  
ture and VCC range  
The DM74ALS138 decodes one-of-eight lines, based upon  
the conditions at the three binary select inputs and the  
three enable inputs. Two active-LOW and one active-HIGH  
enable inputs reduce the need for external gates or invert-  
ers when expanding. A 24-line decoder can be imple-  
mented with no external inverters, and 32-line decoder  
requires only one inverter. An enable input can be used as  
a data input for demultiplexing applications.  
Advanced oxide-isolated, ion-implanted Schottky TTL  
process  
This decoder/demultiplexer features fully buffered inputs,  
presenting only one normalized load to its driving circuit. All  
inputs are clamped with high-performance Schottky diodes  
to suppress line-ringing and simplify system design.
