(Note 1) When mounted on a glass epoxy board (70 mm x 70 mm x 1.6 mm). Derate by 5.04 mW/°C for Ta higher than 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. 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.
