Quadruple 2-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs

The SN74F257 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.
