BU4066BC is an IC (Integrated Circuit) belonging to the category of Interface – Analog Switches, Multiplexers, Demultiplexers. It is produced by the semiconductor manufacturer ROHM, located in Japan. This IC is made up of four switch circuits, with each circuit having an S (Select) terminal and a "D" (Data) terminal. To control these switch circuits, the IC requires a positive voltage between 4 and 18 volts and an external power supply.

The primary application fields of the BU4066BC IC, as enumerated earlier, include analog switches and multiplexers, as well as demultiplexers. It can be used to switch small amounts of current, load large capacitors, and supply power to loads that require higher levels of power. The BU4066BC can be used in a wide variety of applications, such as in signal routing and signal conversion. In addition, it can also be used in light assemblies such as LEDs and LCDs.

The working principle of the BU4066BC is based on the NAND gate. The NAND gate is an electronic device that combines the output of two inputs, A and B, to create a single output. It works in the following manner: the output (C) of the NAND gate is LOW when both of the inputs A and B are HIGH, and the output (C) is HIGH when any of the inputs A and B are LOW. The BU4066BC consists of four NAND gates that are used to control the operating of the switch circuits.

Each of the four NAND gates consists of two inputs (S and D) and one output. When the input S is HIGH, the output (C) is LOW and the switch is set to CLOSED. When the input S is LOW, the output (C) is HIGH and the switch is set to OPEN. By applying suitable input signals to the S and D terminals, the NAND gates can be used to switch any combination of the four switch circuits.

In summary, the BU4066BC IC is a source of multiplexers, demultiplexers and analog switches. Its main applications include signal routing, signal conversion and controlling LEDs and LCDs. Its NAND gate-based working principle enables it to switch any combination of its four switch circuits, making it an ideal choice for such tasks.
