It handles one driver and one receiver, with the receiver offering 50 mV of hysteresis for cleaner signal recovery on long or noisy cable runs. Data rate is rated at 5 Mbps, which covers most Modbus RTU, Profibus, and proprietary RS-485 links without pushing the bus timing margin.
For BOM planning, this is a standard-production TI part with stable lead times through the independent distribution channel.
