| 13 | HD3SS3220 is a USB SuperSpeed (SS) 2:1 mux with DRP port controller. The device provides Channel |
| 14 | Configuration (CC) logic and 5V VCONN sourcing for ecosystems implementing USB Type-C. The |
| 15 | HD3SS3220 can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP) or a |
| 16 | Dual Role Port (DRP) making it ideal for any application. |
