(Noete3)Measured value with ROHM Standard Board (170.0mm×70.0mm×1.6mm, 1layer)
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 to consider circuit protection measures, such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
