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 () 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.
