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

These data selectors/multiplexers SN74AS257 are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable () input is at a high Logic level.
The SN54ALS257A and SN54ALS258A are characterized for operation over the full military temperature range of -55?C to 125?C. The SN74ALS257A SN74ALS258A SN74AS257 and SN74AS258 are characterized for operation from 0?C to 70?C.
