description  
This device is designed to multiplex signals from 4-bit data sources to four output data lines in bus-organized  
systems. The 3-state outputs do not load the data lines when the output-enable (OE) input is at a high logic level.  
The 74AC11257 is characterized for operation from –40°C to 85°C.
