Note 9-3
Output leakage is measured with the current pins in high impedance.
Note 9-4
See the USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics
Note 9-5
RBIAS is a 3.3 V tolerant analog pin.
Note 9-6
Output current range is controlled by program software. The software disables the FET during short
circuit condition.
9.4
Capacitance TA = 25°C; fc = 1 MHz; VDD33 = 3.3 V
