7.1 Application Information
The TUSB4020BI-Q1 is a two-port USB 2.0 hub, which provides USB high-speed/full-speed connections on the upstream port and USB high-speed, full-speed, or low-speed connections on the downstream port. The TUSB4020BI-Q1 can be used in any application that needs additional USB compliant ports. For example, a specific notebook can only have two downstream USB ports. By using the TUSB4020BI-Q1, the notebook can increase the downstream port count to three.
