The TS3USB221DRCR is a high-bandwidth 1:2 multiplexer/demultiplexer USB 2.0 switch with single enable from Texas Instruments, engineered for routing high-speed USB 2.0 signals in space-constrained consumer and handheld applications. Packaged in a compact 10-VSON-10 (DRC), this 480Mbps USB switch delivers a wide 1.1GHz typical bandwidth that passes differential signals with minimal edge and phase distortion. Operating from a 2.3V to 3.6V supply, the bidirectional analog switch multiplexes differential outputs from a USB host to one of two corresponding outputs while accepting signals up to 5.5V on the I/O pins, making it ideal for cell phones, digital cameras, notebooks, and MHL 1.03 portable device routing across the -40°C to +85°C temperature range.
Application Scenarios
As a versatile USB 2.0 routing switch, the TS3USB221DRCR serves diverse portable and consumer electronic domains:
● Cell phones and smartphones routing USB data lines between internal peripherals and external connectors
● Digital cameras and camcorders switching USB ports between data transfer and charging functions
● Notebook and laptop computers expanding limited USB I/Os on controllers through external port multiplexing
● MIPI signal routing in mobile platforms requiring differential pair switching
● Portable media players and tablets managing USB host and device mode transitions
● USB I/O expansion boards and accessories enabling port sharing between multiple functions
● General high-speed differential signal routing in battery-powered applications where low power and minimal signal degradation are critical.
Frequently Asked Questions
Q: Can this switch handle USB 3.0 signals? No, this device is specifically designed for USB 2.0 (480Mbps) and below (USB 1.0/1.1); USB 3.0 SuperSpeed signals at 5Gbps require dedicated high-bandwidth switches from the TSUSB series.
Q: What happens when the OE pin is disabled? When OE is high, the switch disconnects all channels and enters low-power mode consuming only 1µA, while all I/O pins present high-impedance states with just 2µA leakage current maximum.
Replacement Models
1. TS3USB221EDRCR: Enhanced ESD successor with 12000V HBM and 7000V CDM IEC Level 3 protection in the same VSON-10 package for ESD-critical applications.
2. TS3USB221ARSER: 900MHz bandwidth variant with integrated ESD protection cells on all pins in a tiny UQFN package.
3. TS3USB30ERSWR: Higher-bandwidth 1:2 USB 2.0 switch tolerating up to 5.25V signals with IEC 61000-4-2 Level 4 ESD protection.
4. TS3USB3031: 1:3 multiplexer version combining MHL and dual USB 2.0 high-speed switching in a single package for multi-port routing.
