Working Principles

The TS3USB221ARSERG4 is a single-pole double-throw (SPDT) switch that allows bidirectional data flow between a USB host and peripheral devices. It operates by selectively connecting the D+ and D- lines to either the upstream or downstream port based on the control signals received.

When the SEL pin is set to logic low, the switch connects the upstream port to the D+ and D- lines, allowing data transmission from the host to the peripheral device. Conversely, when the SEL pin is set to logic high, the switch connects the downstream port to the D+ and D- lines, enabling data transmission from the peripheral device to the host.

Detailed Application Field Plans

The TS3USB221ARSERG4 is widely used in various applications, including:

  1. Mobile Devices: Enables USB connectivity for smartphones, tablets, and portable media players.
  2. Personal Computers: Facilitates USB switching for laptops and desktop computers.
  3. Consumer Electronics: Allows USB connection in gaming consoles, digital cameras, and audio/video equipment.
  4. Industrial Equipment: Provides USB interface switching in industrial automation systems and control panels.
  5. Automotive Systems: Enables USB connectivity in car infotainment systems and onboard diagnostics.
