    The analog switch terminals can be left floating without problems. Or connect them to ground.

    Hi,

    Sadly you don't tell which pins these are...

    Dedicated CMOS input pins (control pin) should not be left floating.

    Re: CD4053 connect unused pins

    no input pin should be left unconnected - analog or digital

    when I have the space, i like putting in a 0 ohm jumper to ground on a pin by pin basis
    just in case, if i need an extra ???, its relatively easy to remove the jumper and put in a wire.
