The DG387BDJ-E3 is an analog switch, multiplexer, demultiplexer product with three independent channels. It is a CMOS device with a total of four independent switch elements, one each for the three channels and one for the common node. The device is intended as a low-cost alternative for applications that previously used discrete components. It operates from a single 5-V power supply, and has a maximum supply current of 2 mA.

The DG387BDJ-E3 uses an SPI (Serial Peripheral Interface) bus for control, with two outputs (for data and busy signals), and one input (for writing data). The device features an addressable interface that allows the user to control three independent switches with the same register write command. This greatly simplifies control of multiple switches, since switching operation is not limited to one channel at a time.

The working principle of the DG387BDJ-E3 is based on a CMOS logic scheme, in which transistors and resistors form a matrix of N x N switches connected to each other by two or more data wires. The data wires are used to set up the desired switch patterns, with the transistor selection, or switching sequence, determined by the register write command issued to the peripheral bus. The switch state is held until another switching sequence is enabled.

The DG387BDJ-E3 analog switch, multiplexer, demultiplexer is a versatile device that can be used in a wide range of applications. It can be used to route analog signals, such as audio signals and video signals, among different devices. It can be used to switch different transmission channels, such as messaging and voice channels, as well as to switch high-speed data streams, such as HDMI and USB. Additionally, the device can be used in medical instruments, such as ultrasound and X-ray machines, and in the industrial sector, such as PLCs (programmable logic controllers) and motion-control systems.

The DG387BDJ-E3 is a reliable device, with a maximum on-resistance of 40Ω. It also has low off-state leakage current, with a maximum off-state leakage current of 2nA across its three channels. The device also has high signal-to-noise ratio, with a maximum SNR of 85 dB at 1 MHz.

In summary, the DG387BDJ-E3 is an analog switch, multiplexer, demultiplexer product with three independent channels that is used in a wide range of applications. Its working principle is based on a CMOS logic scheme, featuring a SPI bus for control and low on-resistance and off-state leakage current levels. It is a reliable device that provides high signal-to-noise ratio, making it suitable for a variety of applications.
