200 kbps RS-485 transceiver — what the data rate means for the bus
The SN65HVD3082EDRG4: Half-duplex RS-485/RS-422 transceiver in an 8-SOIC package, rated for 200 kbps.
Supply voltage — 5 V only, no 3.3 V operation
If your system is 3.3 V only, you need the 3.3 V-rated variant from the same family (SN65HVD3080E series). The 5 V supply buys you higher common-mode voltage range and better noise immunity on the bus — a trade worth taking when the cable runs through a noisy industrial environment.
Not a full automotive grade (no AEC-Q100 claim in the record), but fine for factory-floor and building-automation hardware that sees ambient temperature swings.
TI lists the SN65HVD3082EDRG4 as Active. No end-of-life notice, no NRND flag. That means it is still a valid choice for new BOM lines and production runs — no LTB scheduling required.
