1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

°C ambient and maximum loading.

3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.

4. This parameter is guaranteed but not tested.
