Frequently asked questions
Does SN65HVD1785D work with 5V supply only?
Yes. The supply range is 4.5V to 5.5V, so it requires a 5V rail. It is not compatible with 3.3V logic supplies.
What is the difference between SN65HVD1785D and SN65HVD1786D?
The SN65HVD1786D is a higher-data-rate variant in the same family. The 1785D is rated for 115Kbps, while the 1786D supports faster signaling. Both are half-duplex RS485 transceivers in the same 8-SOIC footprint and share the same 5V supply and industrial temperature range.
