Hi Team,

If I have unused "S" input pins, what should i do with them? Leave them floating or ground?

Thank you,

Jared

    Switch channel inputs can either be left floating or terminated to GND (which can help reduce signal reflections). However, switch logic inputs, such as Select pins, OE pins, and other logic inputs, should never be left floating. They should  be, by default, tied to either VCC or GND.

    This is also mentioned in the FAQ below:

    Thanks
