If there is no 3.3-V supply on board, an external 5-V supply can support the USB-side power needs. When the
V
CC(5.0)
is connected to an external 5-V supply, the on-chip regulator generates the 3.3-V internal supply rail,
which is used to drive the USB signaling levels at the USB side of the TUSB1105/1106. The logic-side I/Os can
operate at any voltage range from 1.65 V to 3.6 V.
