    AVR110 harman/kardon Triple 2-channel analog multiplexer / demultiplexer BU4053BC / BU4053BCF / BU4053BCFV The BU4053BC, BU4053BCF, and BU4053BCFV are multiplexers / demultiplexers capable of selecting and combin- ing analog signals and digital signals in a 2 ch × 3 configuration. Inhibit signals and control signals are used to turn on the switch corresponding to each of the channels.
