3.1 Absolute Maximum Ratings
Note: Stresses at or above those listed could cause permanent damage to the device. This is a stress
rating only and functional operation of the device at any other condition above those indicated
in the operation sections of this specification is not implied.
Note 3.1 For the 5V tolerant pins that have a pull-up resistor (SMCLK, SMDATA, THERM
, and
ALERT
/ THERM2), the pull-up voltage must not exceed 3.6V when the device is
unpowered.
