The TS3USB221A-Q1 is a high-bandwidth switch specially designed for the switching of high-speed USB 2.0 signals in automotive USB hubs or controllers with limited USB I/Os. The wide bandwidth (900 MHz) of this switch allows signals to pass with minimum edge and phase distortion. The device multiplexes differential outputs from a USB host device to one of two corresponding outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low bit-to-bit skew and high channel-to-channel noise isolation, and is compatible with various standards, such as high-speed USB 2.0 (480 Mbps).

The TS3USB221A-Q1 integrates ESD protection cells on all pins, is available in a tiny UQFN package
(2 mm × 1.5 mm) and is characterized over the free air temperature range from –40°C to 125°C.
