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. Items other than the storage temperature, operating temperature, and power dissipation are all stipulated for an ambient
temperature Ta = 25°C.
3. *1: Ta = 85°C. See the "Application Notes" for details on the relationship between IC power dissipation and the ambient
temperature.
*2: When VCC < 6 V, the following condition must hold: VIN−1 = VIN−2 = VCC − 0.2 V.
