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.
Engineers need precise electrical characteristics and pinout to validate the part in their design.
Buyers compare prices across distributors to minimize BOM cost.
Sourcing buyers need to ensure supply for production schedules.
Though active, techs and brokers check lifecycle to avoid last-time buys or find drop-in alternatives.
Design engineers evaluate alternatives for cost, performance, or availability.
Critical for industrial applications where temperature extremes affect reliability.
