*1 : <About the output short-circuit current>

Output short-circuit current IOS is the maximum current that flows when the output pin is connected to VDDE or VSS (within the maximum rating) . The current is “the short-circuit current per differential output pin.” As the USB I/O buffer is a differential output, the short-circuit current should be considered for both of the output pins.

		Monitor the short-circuit current
	“L” level	“H” output
			Short-circuited at GND level
3-State Enable "L"
			Short-circuited at VDDE level
	“H” level	“H” output
		Monitor the short-circuit current
3-State Enable "L"

*2 : <About Measurement of Z leakage current ILZ>

Input leakage current ILZ is measured with the USB I/O buffer in the high-impedance state when the VDDE or VSS voltage is applied to the bidirectional pin.
