EVALUATION KIT AVAILABLE MAX14853/MAX14855 2.75kVRMS Isolated 500kbps/25Mbps Full-Duplex RS-485/RS-422 Transceivers with ±35kV ESD Protection and Integrated Transformer Driver General Description The MAX14853/MAX14855 isolated RS-485/ RS-422 transceivers provide 2750VRMS (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 500kbps (MAX14853) or 25Mbps (MAX14855). The MAX14853/MAX14855 include an integrated 450kHz transformer driver for power transfer to the cable-side of the transceiver using an external transformer.
