Note: 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 conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
Note:The HSB
pin has I
OUT
=-10uA for V
OH
of 2.4V, this parameter is characterized but not tested.
Note:The INT is open-drain and does not source or sink high current when interrupt Register bit D3 is below.
