Inputting Logic Level
Please connect to GND pin first to protect GPIO pin and then input voltage to Line2
pin.
2.
Configure Line2 to output pin
The available maximum current is 25mA and the output impedance is 40Ω.
When the environment temperature is 25 degree centigrade, the relationship among
external voltage, impedance and the output low level can be shown in Table 3-7.
