(Note 1) Reduce by 4.68mW/°C over 25°C. (On 70.0mm×70.0mm×1.6mm glass epoxy board)

(Note 2) This value is not to exceed Pd.

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.

○Product structure：Silicon monolithic integrated circuit ○This product has no designed protection against radioactive rays
