This is a stress rating only, and functional operation of the device at con- ditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rat- ing conditions for extended periods may affect reliability. DC CHARACTERISTICS (VCC = 2.7V-3.6V) Note: The HSB pin has IOUT = -10 uA for VOH of 2.4 V. This parameter is characterized but not tested.
