s 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 17).)

• Precaution must be taken on the pin 13 and pin 16 due to approximately 200 V of the static breakdown voltages.

(C = 200 pF, R = 0 Ω)
