ISO1212: Power consumption if using only 1 of 2 channels

Part Number: ISO1212

Hi,

If I use only Channel 1 of the ISO1212 part, will how I connect the unused pins affect the quiescent current consumption?

Is it best practice to leave all the Channel 2 pins (5, 9, 10, 11, 12) unconnected?

Thank you!

Best Regards,
