description  
The F257 is designed to multiplex signals from  
4-bit data sources to 4-output data lines in  
bus-organized systems. The 3-state outputs will  
not load the data lines when the output enable  
(OE) input is at a high logic level.

The SN54F257 is characterized for operation over  
the full military temperature range of 55°C to  
125°C. The SN74F257 is characterized for  
operation from 0°C to 70°C.
