(Note 3) Mounted on a 1-layer.74.2mmx74.2mmx1.6mm glass-epoxy board, occupied area by copper foil : 10.29mm²
(Note 4) Mounted on a 4-layer 74.2mmx74.2mmx1.6mm glass-epoxy board, occupied area by copper foil : 10.29mm² , in each layers

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
