Quad 2ch Analog Multiplexer/Demultiplexer
BU4551B BU4551BF BU4551BFV
General Description
The BU4551B, BU4551BF, BU4551BFV are multiplexers/demultiplexers with capabilities of selection and mixture of analog signal and digital signal. This series are configured with quad 2 channels input/output. The digital signal of the control terminal turns on the corresponding switch of each channel.
The large am plitude
voltage (VDD-VEE) can be switched by the control signal with small logical amplitude
voltage (VDD-VSS).
