(Note 1) Mounted on 74.2mm x 74.2mm x 1.6mm glass epoxy 1layer board (Copper foil area : 10.29mm2). Reduce 5.5mW 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.
