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). 5 GND The TS3USB221A integrates ESD protection cells on all pins, is available in a tiny µQFN package (2.0 mm × 1.5 mm) and is charaterized over the free air temperature range from –40°C to 85°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system.
