Is there any simple way to make a bidirectional switch using MOSFET chip?
If you use two MOSFETs, then you get a bidirectional switch.

There are many ways to get a floating gate drive, depending on your other specifications. For the highest isolation, you can buy an opto-isolator with a photo-voltaic output. If you can cope with a little current on the channel then you can trickle in some bias through a large resistor. There are plenty of other options with transformers or local batteries, which become more or less practical depending on how many channels you want to run.
