At 20Mbps, the MAX3045BCUE+ supports high-speed RS422/RS485 links such as camera data, industrial encoder feedback, or multi-drop instrumentation busses. This is roughly double the 10Mbps ceiling of many legacy RS485 drivers, so it keeps the bus timing margin cleaner on longer cable runs or daisy-chained nodes. The 4/0 driver/receiver count means you need an external RS485 receiver on the same bus if bidirectional communication is required.
