3. For conditions shown as Max or Min, use appropriate value specified under Electrical Characteristics for the applicable device type.
4. Typical values are at V

C ambient and maximum loading.
5. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
6. This parameter is guaranteed but not tested.
7. This parameter is determined by device characterization but is not production tested.
8. V

or GND.
10. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
