Note a: Stresses greater than those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device. 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.

Note: The INT pin is open-drain and does not source or sink high current when Interrupt Register bit D3 is low.
