RS-485 bus interface in a standard 8-SOIC footprint

Supply rail and temperature — fit for the BOM

The 5V nominal supply (4.75V min, 5.25V max) ties this part to legacy 5V logic rails or a regulated 5V bus. If your design runs on 3.3V I/O, this transceiver needs a level translator or a separate 5V supply. For those applications, look at the industrial-temperature variants in the SN75176 family.

For new designs, it remains a valid choice, and for existing BOMs, there is no imminent obsolescence risk to trigger a requalification cycle.

Frequently asked questions

What is the difference between SN75176BPSR and SN75176BDR?

Both are the same base SN75176 half-duplex RS-485 transceiver. The difference is in the packaging and reel format: the BPSR suffix indicates a different tape-and-reel specification compared to the BDR suffix. Electrically and functionally they are identical. The choice between them depends on your assembly house's preferred reel packaging or your inventory system's part-number convention.
