BU4066BC series is a four-channel single-pole double-throw switch that can control digital or analog signals. BU4051BC/BU4052BC/BU4053BC/BU4551B series are analog selectable composite multiplexers/demultiplexers. BU4051BC series is configured with 8 channels, BU4052BC series is configured with two 4 channels, BU4053BC series is configured with three 2 channels, BU4551B series is configured with four 2 channels, and switches applicable for each channel are turned on according to digital signals of control terminal. Even if the logic amplitude (VDD-VSS) of the control signal is small, signals of large amplitude (VDD-VEE) can be switched.
This technical note describes the BU4066BCFV high‑voltage CMOS analog switch, including its features, recommended operating conditions, and detailed electrical characteristics. The document also lists related parts in the BU4S and BU4000B series and provides reference data and packaging information.
The BU4066BCFV is intended for use as a low‑ON‑resistance switch and chopper modulation circuit for analog and digital signals, suitable for high‑speed lines without degrading audio or video signals.
