TS3USB221E / TS3USB31E High-Speed USB Switches

Texas Instruments TS3USB221E and TS3USB31E High-Speed USB Switches are high-bandwidth devices specially designed for the switching of high-speed USB 2.0 signals in the handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os. The wide bandwidth of these TI USB switches allows signals to pass with minimum edge and phase distortion. The TI TS3USB221E USB switch multiplexes differential outputs from a USB host device to one of two corresponding outputs. The Texas Instruments TS3USB221E and the TS3USB31E are both bidirectional and offer little or no attenuation of the high-speed signals at the outputs. These TI devices are designed for low bit-to-bit skew and high channel-to-channel noise isolation and are compatible with high-speed USB 2.0 (480 Mbps) and various standards.
