Note) 1. Do not apply external currents or voltages to any pins not specifically mentioned.
For circuit currents, '+' denotes current flowing into the IC, and '-' denotes current flowing out of the IC.
2. *1: Except for the power dissipation, the operating ambient temperature and storage temperature, all ratings are for T
a
= 25°C.
*2: The power dissipation shown is the value for T
a
= 75°C.
*3: Do not over the supply voltage.
