(Note 1) 74.2mm×74.2mm×1.6tmm FR4 1Layer Glass epoxy base Surface Copper foil 0%）Mounting
Above Ta=25℃,reduced by 8.0mW/℃. Thermal beer is on a base.
(Note 2) 74.2mm×74.2mm×1.6tmm FR4. 4 Layer Glass epoxy base（2,3layer Copper foil 100%）Mounting
Above Ta=25℃, reduced by 30.12mW/℃. Thermal beer is on a base.
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.
