DATASHEET
Note 8.3 Output leakage is measured with the current pins in high impedance.
Note 8.4 See USB 2.0 Specification for USB DC electrical characteristics.
Note 8.5 Max supply current was measured under ICH10 EHCI controller while transferring files in
Windows7 using fastest available HDs, at VDD=3.3V+20% and T (case) temperature -55C.
