Note 1: When standard value of voltage (50Hz) between VR and Vi is minimum, and output OS is low-level, or when standard value of voltage (50Hz) between VR and Vi is maximum, and output OS is high-level.
Note 2 : When standard value of voltage VLAON is minimum, and output OS is low-level, or when standard value of voltage VLAON is maximum, and output OS is high-level.
Note 3: Supply current 2 is necessary to keep high in output OS.
Note 4: After applying 30mV  between VR and Vi and shorting between them.
Note 5: After the 12V supply voltage is applied and the output is set to high level, reduce the supply voltage output to low level and measure the voltage drop.
Note 6:Operating time is a time from applying fixed input till operating latch circuit in 0.047μF between OD and GND.
