The Renesas RS-485/RS-422 Transceiver is 3.3V to 5V powered, fault protected, extended common-mode range differential transceivers for balanced communication. The RS-485 bus pins, driver outputs and receiver inputs are protected against overvoltage's up to ±40V and against ±15kV ESD strikes. Additionally, these transceivers operate in environments with common-mode voltages up to ±15V (exceeds the RS-485 requirement), making this RS-485 family one of the most robust on the market.

±15kV HBM ESD protection on RS-485 bus pins
