3 Description

The TUSB8041 is a four-port USB 3.0 hub. It

provides simultaneous SuperSpeed USB and highspeed/

full-speed connections on the upstream port

and provides SuperSpeed USB, high-speed, fullspeed,

or low-speed connections on the downstream

ports. When the upstream port is connected to an

electrical environment that only supports high-speed

or full-speed/low-speed connections, SuperSpeed

USB connectivity is disabled on the downstream

ports. When the upstream port is connected to an

electrical environment that only supports fullspeed/

low-speed connections, SuperSpeed USB and

high-speed connectivity are disabled on the

downstream ports.
