HD3SS6126 USB 2.0 and USB 3.0

Texas Instruments' HD3SS6126 is a high-speed passive switch that is designed for USB 3.0 applications to route signals from a source to two destinations or vice-versa. It can also be used for DisplayPort, PCIe, SATA, SAS, and XAUI applications. The HD3SS6126 can be used in either sink- or source-side applications.

The HD3SS6126 is offered in a 42-pin WQFN package and specified to operate from a single-supply voltage of 3.3 V over the temperature range of 0°C to 70°C.
