Please ground both 7pin and 14pin of GND.
Power supply terminal of the non-use connect to the GND through low resistance or directly.
Please open output terminal.
Open the electric potential of the die pad on the back side of the package or connect the die pad to the GND.
When the die pad is connected to the GND, do not use the die pad as the electrode unless shorting with 7 pinor 14pin.

Pull-up voltage
DOUT
①②③t

①．DOUT becomes the high voltage (pull-up voltage) when the power supply voltage VDD is lower than the releasevoltage +VDET.
②．DOUT switches to low voltage from high voltage when the power supply voltage VDD rises above the releasevoltage +VDET.
③．DOUT switches to high voltage from low voltage when the power supply voltage VDD falls below the detection
voltage -VDET.
