DM74S138 • DM74S139  
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  
■ DM74S138 3-to-8-line decoders incorporates 3 enable  
inputs to simplify cascading and/or data reception  
■ DM74S139 contains two fully independent 2-to-4-line  
decoders/demultiplexers  
■ Schottky clamped for high performance  
■ Typical propagation delay time (3 levels of logic)  
DM74S138 8 ns  
The DM74S138 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 a 32-line decoder  
requires only one inverter. An enable input can be used as  
a data input for demultiplexing applications.  
DM74S139 7.5 ns  
■ Typical power dissipation  
DM74S138 245 mW  
DM74S139 300 mW  
The DM74S139 comprises two separate two-line-to-four-  
line decoders in a single package. The active-LOW enable  
input can be used as a data line in demultiplexing applica-  
tions.  
All of these decoders/demultiplexers feature 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 sys-  
tem design.
