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. VoH = Vcc – 0.6V at rated current
