Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The DC input voltage on any pin should not be lower than −0.5 V or higher than V_CC + 0.5 V. The A₀ pin can be raised to a HV level for RSWP
command execution. SCL and SDA inputs can be raised to the maximum limit, irrespective of V_CC.

3. 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.
