Texas Instruments SN74AHC257/SN74AHC257-Q1 2-To-1 Line Data Sel/Mux
Texas Instruments SN74AHC257/SN74AHC257-Q1 2-To-1 Line Data Selector/Multiplexers are quad 2-input data selector/multiplexers with 3-state outputs. Shared A/B and OE inputs control all channels. The 3-state outputs can interface with and drive data lines of bus-organized systems. The output-enable (OE) input controls all outputs simultaneously. The Texas Instruments SN74AHC257-Q1 devices are AEC-Q100 qualified for automotive applications.
