Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Refer to ELECTRICAL CHARACTERISTICS, RECOMMENDED OPERATING RANGES and/or APPLICATION INFORMATION for Safe
Operating parameters.
2. For information, please refer to our Soldering and Mounting Techniques Reference Manual, SOLDERRM/D.
3. The DC input voltage on any pin should not be lower than −0.5 V or higher than V_CC + 0.5 V. SCL and SDA inputs can be raised to the
maximum limit, irrespective of V_CC. During transitions, the voltage on any pin may undershoot to no less than −1.5 V or overshoot to no more
than V_CC + 1.5 V, for periods of less than 20 ns.

4. Power Dissipation is defined as P_J = (T_J − T_A)/q_JA, where T_J is the junction temperature and T_A is the ambient temperature. The thermal
resistance value refers to the case of a package being used on a standard 2−layer PCB.
