Notes 1. VDD5: Clamping diode-dedicated power supply
2. By supplying 5 V for clamping diode, the device can be protected from an 11-V reflection wave.
Caution If any of the parameters exceeds the absolute maximum ratings, even momentarily, the quality of
the product may be impaired. The absolute maximum ratings are values that may physically
damage the product(s). Be sure to use the product(s) within the ratings.
