(Note 1) Derate by 7.0mW/°C if operating over Ta=25°C. (On 70.0mm×70.0mm×1.6mm glass epoxy board)  
(Note 2) Do not exceed Pd and Tjmax.  
(Note 3) Ta=0°C or Higher.  
(Note 4) Less than Ta=0°C.  
Caution: 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.
