Hi Team,
Should we pull up the non-use output pin or it's ok to leave output floating?
Thanks.

Hi Andrew,
Leaving unused ports open should not cause an issue for the device, though the floating pins may be susceptible to noise which may cause undesired behaviors. We generally recommend tying unused ports to Vcc through weak pull-ups (~100k). This provides a stable state in case the channel is inadvertently enabled.

Eric
