(Note 1) Supply voltage is limited by internal clamping circuit .

Please refer to maximum current voltage of the electrical characteristic item.

(Note 2) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 4.5mW 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.
