Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
8. Devices that use non−standard supply voltages which do not conform to the intent I2C bus system levels must relate their input levels
to the VDD voltage to which the pull−up resistors RP are connected.
9. Refer to the Application Information section of this data sheet for more details.
