Quad 2-channel analog multiplexer / demultiplexer BU4B / BU4BF / BU4BF The BU4B, BU4BF, and BU4BF are multiplexers / demultiplexers capable of selecting and combining analog signals and digital signals with a configuration of 2 ch 4. Control signals are used to turn on the switch of the corresponding channel. In addition, even if the logical amplitude (-SS) of the control signal is low, signals with a large amplitude (-) can be switched. In addition, as each switch has a low ON resistance, it can be connected to a low impedance circuit.
