Derate by 21.3mW when operating above 25C.

Caution1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit

between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over

the absolute maximum ratings.

Caution2: Long-term reliability may be influenced when operated at or near the absolute maximum rating.
