Notes
9. 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.
10. The HSB\ pin has IOUT = -8 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.
11. VCAP (storage capacitor) nominal value is 88 uF total cap.
