Notes

11.Typical conditions for the active current shown on the DC Electrical characteristics are average values at 25°C (room temperature), and VCC = 3V. Not 100% tested.

12.The HSB pin has IOUT = -2 uA for VOH of 2.4V when both active HIGH and LOW drivers are disabled. When they are enabled standard VOH and VOL are valid. This parameter is characterized but not tested.

13.VCAP (Storage capacitor) nominal value is 68uF.
