TUSB2077A Description
The TUSB2077A hub is a 3.3-V CMOS device that provides up to seven downstream ports in pliance with the USB 2.0 specification. Because this device is implemented with a digital state machine instead of a microcontroller, no software programming is required. Fully pliant USB transceivers are integrated into the ASIC for all upstream and downstream ports.
