Isolated RS-485

Analog Devices offers a wide range of standard RS-485/RS-422 transceivers and iCoupler® isolated RS-485/RS-422 transceivers to suit many applications. The RS-485 specification meets the requirements for a truly multipoint communications network, and the standard specifies up to 32 drivers and 32 receivers on a single (2-wire) bus. Some RS-485 transceivers modify the input impedance to allow up to 8× more nodes to be connected to the same bus.
