60V OVP, 20V CMR, -4085,

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
Wide supply range of 3V to 5.5V
1/4 unit load for up to 128 devices on the bus
High transient overvoltage tolerance of ±60V
Full fail-safe (open, short, terminated) RS-485 receivers
Choice of RS-485 data rates of 250kbps or 1Mbps
Pb-free (RoHS compliant)
