MAX14857/MAX14859 RS-485/RS-422 Transceivers

Analog Devices MAX14857/MAX14859 RS-485/RS-422 Transceivers are isolated RS-485/RS-422 transceivers that provide 5000VRMS (60s) of galvanic isolation. This isolation is provided between the cable side (RS-485/RS-422 driver/receiver side) and the UART side of the device. The 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 500kbps (MAX14857) or 25Mbps (MAX14859). The devices include an integrated 450kHz transformer driver for power transfer to the cable side of the transceiver using an external transformer. An integrated LDO provides a simple and space-efficient architecture for powering the cable side of the IC.
