说明

The TUSB8040 is USB 3.0 compliant hub available in an 80-pin QFP package. The device is designed for operation over the industrial temperature range of –40°C to 85°C.

The TUSB8040 provides simultaneous SuperSpeed and high-speed/full-speed connections on the upstream port and provides SuperSpeed, high-speed, full-speed, 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 connectivity is disabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed/low-speed connections, SuperSpeed and high-speed connectivity are disabled on the downstream ports.
