Caution:Operating the IC over the absolute maximum ratings may damage the IC.The damage can either be a short circui 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.
