*1. When the product without a pull-up resistor is selected.
*2. When the product with a pull-up resistor is selected.
*3. When Nch open-drain output is selected.
*4. When CMOS output is selected.
*5. Conditions with no condensation or frost. Condensation or frost causes short-circuiting between pins, resulting in a
malfunction.
Caution The absolute maximum ratings are rated values exceeding which the product could suffer physical
damage. These values must therefore not be exceeded under any conditions.
