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