Note 1: Maximum test duration not to exceed one second, not more than one output shorted at one time.
Note 2: This parameter guaranteed but not tested.

Note 4: This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
Note 5: Values for these conditions are examples of the I formula. These limits are guaranteed but not tested.
