Remark
Datasheet
The Max value of Input voltage/Output voltage is not over 6.5V.
When the pulse width is 50ns or less, the Min value of Input
voltage/Output voltage is not lower than -1.0V.
Junction temperature at the storage condition
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.
