MAX2202x/F Isolated RS-485/RS-422 Transceivers

Analog Devices MAX2202x/F Isolated RS-485/RS-422 Transceivers provide 3.5kV_RMS of digital galvanic isolation between the cable side (RS-485/RS-422 driver/receiver side) and the UART side of the device. Isolation improves communication by breaking ground loops and reducing noise when there are large differences in ground potential between ports. These devices allow for robust communication up to 0.5Mbps or 16Mbps.
