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.
