The ′AC11238 circuit 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  
9 10 11 12 13  
NC – No internal connection  
and the enable time of the memory are usually less than the typical access time of the memory. This means that  
the effective system delay introduced by the decoder is negligible.  
The conditions at the binary select inputs and the three enable inputs select one of eight input 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.  
The 54AC11238 is characterized for operation over the full military temperature range of – 55°C to 125°C. The  
74AC11238 is characterized for operation from – 40°C to 85°C.
