The analog switches that I have recently found, opened a new window for me. Could I use the analog switches, like MAX323, like a relay? To better explain what I am thinking, if I have circuit that works with 3V, could I use the switch to close and open a 24V line coming from outside world, thus imititating the SPST relay?
