s Usage Notes
• Prevent this IC from being line-to-ground fault.
(To be concrete, do not short-circuit any of A1 (pin 3), A2 (pin 1) and A3 (pin 31) with GND pin (pin 10).)
• Be careful of the following three pins because their static breakdown voltages are low. (C = 200 pF, R = 0 Ω)
Pin 11: breakdown at 80 V
Pin 14: breakdown at 90 V
Pin 24: breakdown at 190 V
