For a production BOM that already specifies this part, the remaining supply channel is independent distribution — surplus stock, new-old-stock, or broker-sourced units.
200 kbps — the speed that fits the bus
Rated at 200 kbps, this transceiver is sized for legacy RS-485 and RS-422 links where noise immunity and cable length matter more than throughput — think factory-floor sensor networks, building automation, and motor-drive communication links. The 30 mV receiver hysteresis cleans up slow edges on long twisted-pair runs, reducing the chance of chatter on an idle bus. If your design needs higher baud rates, you are looking at a different part family; for the 200 kbps tier, this is the part.
5 V rail and the retrofit angle
If the board it is replacing or repairing runs on a 5 V rail — common in older PLC I/O modules, VFD control cards, and serial gateway boards — the SN65HVD3082ED fits without a voltage translation stage. The 8-SOIC footprint is a standard, widely supported land pattern that places cleanly on a two-layer board with basic decoupling.
