TUSB2046BI Overview
The TUSB2046x is a 3.3-V CMOS hub device that provides one upstream port and four downstream ports in pliance with the Universal Serial Bus (USB) specification as a full-speed hub. Because this device is implemented with a digital state machine instead of a microcontroller, no firmware programming is required. Fully pliant USB transceivers are integrated into the ASIC for all upstream and downstream ports.
