 Make sure the input voltage is not from 1 VDC to 1.5 VDC. The circuit status between the two
values is not stable.
 The breakdown voltage is 30 VDC, and keep voltage stable.
 To prevent damage to the GPIO pin, connect GND first and then input voltage in Line 2 pin.

The maximum current is 25 mA and the output impedance is 40 Ω.
When the environment temperature is 25 °C (77 °F), the relation among external voltage,
resistance and the output low level is shown below.
