(Note1) SOP-J8 : When mounted (on 70 mm × 70 mm, 1.6 mm thick, glass epoxy on single-layer substrate)

De-rated by 5.4mW/°C when operating above Ta=25°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.
