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 3.3V tolerant analog pin.

Note 9.6 Output current range is controlled by program software. The software disables the FET during short circuit condition.

Note 9.7 The 3.3V supply should be at least at 75% of its operating condition before the 1.8V supply is allowed to ramp up.

9.4Capacitance

TA = 25°C; fc = 1 MHz; VDD33 = 3.3V , VDD18 = 1.8V
