The MAX14856/MAX14858 isolated RS-485/RS-422 transceivers provide 5000 VRMS (60s) of 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 reduces noise when there are large differences in ground potential between ports. These devices allow for robust communication up to 500 kbps (MAX14856) or 25 Mbps (MAX14858).The devices are available in a wide-body 16-pin SOIC package and operate over the -40° C to +105° C temperature range.
