Usage Notes
Prevent this IC from being line-to-ground fault.
(To be concrete, do not short-circuit any of A31 (pin 21), A32 (pin 22), A21 (pin 24), A22 (pin 25), A11 (pin 27) and
A12 (pin 28) with GND pin (pin 15).)
Be careful of the following three pins because their static breakdown voltages are low. (C

Pin 23: breakdown at 120 V
Pin 26: breakdown at 120 V
