It is the question from our customer.
Is SW open in power supply OFF?
I think that I become open (high impedance), how about?
The state of the switch with no power supplied is not gaurantteed. In addition if a signal is applied to the unpowered switch it can turn the switch on and forward bias the ESD diodes. To avoid these risks I would recommend to use the ADG4612/ADG4613 switches as they are gaurantteed to be off when no power is supplied.
Thanks for advice.
