The ’AHC138 decoders/demultiplexers are  
designed for high-performance memory-decoding  
and data-routing applications that require very  
NC – No internal connection  
short  
propagation-delay  
times.  
In  
high-performance memory systems, these  
decoders 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 these decoders and the  
enable time of the memory are usually less than  
thetypicalaccesstimeofthememory. Thismeans  
that the effective system delay introduced by the  
decoders is negligible.  
The conditions at the binary-select inputs and 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.  
TheSN54AHC138 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74AHC138 is characterized for operation from –40°C to 85°C.
