Working Principles

The PI3USB102EZLEX is a bidirectional USB switch that allows for seamless switching between two USB ports. It operates based on the control signals received through the I2C interface. When the SEL pin is set to port 1, the switch connects USB port 1 to the output pins. Similarly, when the SEL pin is set to port 2, USB port 2 is connected to the output pins. The OE pin controls the output enable/disable function.

Detailed Application Field Plans

The PI3USB102EZLEX finds applications in various fields, including:

  1. Mobile devices: Enables switching between different USB interfaces, such as charging ports and data transfer ports.
  2. Computers and laptops: Facilitates switching between multiple USB peripherals, such as printers, scanners, and external storage devices.
  3. Audio/video equipment: Allows for easy switching between USB inputs for audio and video devices, such as speakers, microphones, and cameras.
  4. Automotive systems: Enables switching between different USB connections in car infotainment systems, such as media players and mobile devices.
