Mounted on 70mm x 70mm x 1.6mm glass-epoxy PCB. Derating : 6.8mW/ oC above Ta=25 oC.

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.
