Dual Independent Channels: Integrates two fully independent SPDT switches, allowing simultaneous or individual control of two USB differential pairs (D+/D-) for more complex routing logic.
USB 2.0 High-Speed Compliance: High bandwidth of 1.1 GHz and low insertion loss ensure excellent signal eye diagrams and jitter performance even at 480 Mbps full-speed data rates.
Very Low On-Resistance & Flatness: Only 6 Ω on-resistance with excellent flatness across the bandwidth minimizes signal attenuation and distortion.
Wide Low-Voltage Single-Supply Operation: A supply range of 2.3V to 3.6V is compatible with mainstream low-voltage systems (e.g., 2.5V, 3.3V), facilitating integration and offering low power consumption.
Miniature High-Density Package: The small 10-pin UQFN package accommodates dual-channel functionality in limited space, meeting the stringent size requirements of modern portable devices.
USB Port Multiplexing & OTG Switching: Enables intelligent switching of Micro-USB or Type-C ports between host, device, and charging modes in mobile devices.
Docking Stations & Port Replicators: Used to switch connections between multiple downstream USB ports and a single upstream port on a dock, or to implement composite video and data interface functionality.
Multi-Path USB Signal Gating: Routes multiple USB devices to a single host controller in test equipment or industrial computers for automated testing or device management.
Device Detection & Interface Configuration: Automatically routes data signals to the corresponding internal processing circuitry (e.g., UART to USB) based on the type of cable or accessory inserted.
Consumer Electronics & Computer Peripherals: Widely used in laptops, desktop motherboards, monitor USB hubs, and various scenarios requiring flexible USB connection management.
The TS3USB221RSER is a highly integrated, high-performance dual-channel USB analog switch. Its dual-channel design offers greater design flexibility, while its exceptional high-speed signal handling capability ensures the quality and reliability of USB 2.0 links. Whether used to implement complex USB interface functionalities or to build efficient signal routing systems in space-constrained environments, this device provides a standards-compliant, stable, and high-performance solution.
