TUSB8041I Typical Application

The TUSB8041 is a four-port USB 3.0 compliant hub. It provides simultaneous SuperSpeed USB and highspeed/full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full-speed, or low speed connections on the downstream port. The TUSB8041 can be used in any application that needs additional USB compliant ports. For example, a specific notebook may only have two downstream USB ports. By using the TUSB8041, the notebook can increase the downstream port count to five.
