For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
Typical values are at Vcc = 3.3V, 25°C ambient.
This parameter is guaranteed but not tested.
Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
