## Description

The TS3USB221A from Texas Instruments is a high-bandwidth switch designed for high-speed USB 2.0 signal routing in consumer electronics. It functions as a 1:2 multiplexer and demultiplexer, allowing differential USB signals to be directed to one of two outputs with minimal distortion.

Key electrical specifications include a typical bandwidth of 900MHz, supporting USB 2.0 speeds up to 480Mbps. The switch features a low on-resistance of 6 Ohms maximum and a typical channel-to-channel on-resistance match of 0.2 Ohms. It operates with VCC from 2.5V to 3.3V and supports VI/O signals up to 5.5V, with 1.8V compatible control inputs.

Integrated ESD protection is provided on all pins, rated at 7000V for the human-body model (HBM) and 12kV for I/O to GND. The device also includes a low-power mode, reducing consumption to 1µA when disabled, making it suitable for battery-powered applications. It is characterized for operation from -40°C to 85°C.

The TS3USB221A is available in a compact 2mm x 1.5mm UQFN package, ideal for space-constrained designs in mobile phones, cameras, and notebooks.
