Technical details

20 Mbps full-duplex RS-485 transceiver for industrial links

It handles signaling at 20 Mbps, which puts it in the high-speed tier for RS-485 — fast enough for Profibus, Modbus TCP gateway backplanes, or servo drive encoder links where the bus isn't the bottleneck. The 70 mV of receiver hysteresis gives you noise margin on long cable runs without external biasing resistors.

The full industrial temperature span means you don't derate for ambient heat soak or cold-start conditions. Surface-mount 8-SOIC footprint keeps the board area small and matches standard RS-485 transceiver layouts.
