Working Principles

The PI3USB14-AQEX operates by selectively connecting one of the two USB inputs (A or B) to the output (IN/OUT) based on the control signals provided. When the control signal is set to A, the input A is connected to the output, and when the control signal is set to B, the input B is connected to the output. This allows for easy switching between different USB sources or devices.

Detailed Application Field Plans

The PI3USB14-AQEX can be used in various electronic devices that require USB switching capabilities. Some potential application fields include:

1. Portable Devices: Enables switching between different USB peripherals such as charging ports, data transfer interfaces, etc.
2. Computer Systems: Facilitates switching between multiple USB devices, such as printers, scanners, and external storage devices.
3. Automotive Electronics: Allows for seamless switching between different USB inputs in car infotainment systems or charging ports.
