Storage Temperature Range

(Note 1) Not to exceed Pd

(Note 2) Mounted on 24mm x 20mm x 1.6mm glass epoxy board. Reduce 1.00mW per 1°C above 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.
