*1 : <About the output short-circuit current>
Output short-circuit current I
OS is the maximum current that flows when the output pin is connected to VDDE
or V
SS (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.
*2 : <About Measurement of Z leakage current I
LZ>
Input leakage current I
LZ is measured with the USB I/O buffer in the high-impedance state when the VDDE
or V
SS voltage is applied to the bidirectional pin.
