QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXERS WITH 3-STATE OUTPUTS

These data selectors/multiplexers SN54ALS257A SN54ALS258A SN74ALS257A SN74ALS258A SN74AS257 SN74AS258 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 (OE) input is at a high Logic level. The SN54ALS257A and SN54ALS258A are characterized for operation over the full military temperature range of 55C to 125C. The SN74ALS257A SN74ALS258A SN74AS257 and SN74AS258 are characterized for operation from 0C to 70C. By Texas Instruments
