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.
