产品概述
These data selectors/multiplexers 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.
