Chapter 3 Electrical Specifications

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,SYS_SHDN and

ALERT), the pull-up voltage must not exceed 3.6V when the device is unpowered.
