Note 10.1 Output leakage is measured with the current pins in high impedance.

Note 10.2 See the USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics Note 10.3 RBIAS is a 3.3 V tolerant analog pin.

Note 10.4 Output current range is controlled by program software. The software disables the FET during short circuit condition.

Note 10.5 Please refer to the USB 2.0 supplement “High-Speed Inter-Chip USB Electrical Specification Revision 1.0 as of September 23, 2007” which can be obtained from http://www.usb.org/developers/docs/docs.

Note 10.6 Typical and maximum values were characterized using the following temperature ranges: The USB4640 supports the commercial temperature range of 0°C to +70°C

The USB4640i supports the industrial temperature range of -40°C to +85°C
