Hello expert,

I would like to use TMUX1109RSVR as a replacement for TMUX1209RSVR.

The packages are interchangeable, but I think the VSS pin is the difference.

Is it possible to set the VSS pin of the TMUX1109RSVR to OPEN?

Regards,

Hi Ryoma,

Unfortunately it won't be possible. VSS is a supply pin, so floating it would likely cause inconsistent and unpredictable operation. You'd have to pull it down to ground or some other negative supply.

Thanks,
Rami
