is switching. Make sure to leave adequate margin for this IC variation.
Parasitic diodes can occur inevitably in the structure of the IC. The operation of parasitic diodes can
result in mutual interference among circuits as well as operation faults and physical damage. Accordingly
you must not use methods by which parasitic diodes operate, such as applying a voltage that is lower than
the GND (P substrate) voltage to an input pin.
A P-N junction is formed from this P layer of each pin. For example, the relation between each potential

○(When GND > PinB and GND > PinA, the P-N junction operates as a parasitic diode.)
○(When PinB > GND > PinA, the P-N junction operates as a parasitic transistor.)
