Note) 1. Do not apply external currents or voltages to any pins not specifically mentioned.

For the circuit currents, '+' denotes current flowing into the IC, and '−' denotes current flowing out of the IC.

2. Except for the power dissipation, operating ambient temperature, and storage temperature, all ratings are for Ta = 25°C.

3. *1: Ta = 85 °C. For the independent IC without a heat sink. Note that applications must observe the derating curve for the

relationship between the IC power consumption and the ambient temperature.

*2: VIN−1 , VIN-1 , VIN+2 = VCC when VCC < 6 V.
