Notes:

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

2. Typical values are at Vcc = 3.3V, 25

°C ambient.

3. This parameter is guaranteed but not tested.

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

5. VoH = Vcc – 0.6V at rated current
