ADuM162N1 Isolator unused channel connections?

Question

Hello, if one channel input/output is not used how to prevent the ambiguous floating condition? Can input pin of this channel be connected to GND or Vdd ? Directly or through a resistor?

Hi, 
 Yes, the unused channel input should be tied high or low via a weak pull up resistor to prevent the output from toggling in a noisy environment. I would recommend setting the channel input to the lower power consumption state where the transmitter is off. Tie the input high for the ADuM162N1 and low for the ADuM162N0 to do so. The output channel would be left floating.
