Notes
4. Outputs shorted for no more than one second. No more than one output shorted at a time.
5. Typical conditions for the active current shown on the front page of the data sheet are average values at 25°C (room temperature), and VCC = 3V. Not 100% tested.
6. The HSB pin has IOUT = –10 µA for VOH of 2.4 V, this parameter is characterized but not tested.
