Isolated RS-485 transceivers

Highest working-voltage, highest noise immunity and smallest solution size

Explore our portfolio of basic and reinforced isolated RS-485 transceivers based on a proprietary silicon dioxide (SiO2) insulation barrier for industry-leading performance. This family of products integrates the functionality of a digital isolator and RS-485 transceiver into one compact device.

Featured isolated RS-485 transceivers


The ISO1410 is a noise-immune isolated RS-485 transceiver that offers integrated protection features and a robust 5-kVrms isolation barrier with profibus compliance.


The tiny DBQ package of the ISO1500 isolated RS-485 transceiver is 1/3 the solution size of wide-body SOIC packages. The ISO1500 isolated transceiver has a robust 2.5-kVrms isolation barrier.
