1.
When a voltage exceeding 10V is applied to ports 12, 13 and 14, the power supply impedance (pull-up resistor)
should be 50K
or more.
2.
Effective value should be calculated: [Effective value] = [Peak value]

Note
Product quality may suffer if the absolute maximum rating is exceeded for even a single parameter or even
momentarily.
The absolute maximum ratings are rated values at which the product is on the verge of suffering physical
damage, and therefore the product must be used under conditions which ensure that the absolute
maximum ratings are not exceeded.
