component
SN65HVD1781DR
Public Made by Adomby adom
Texas Instruments RS-485 / RS-422 ICs, SOIC-8. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.

orderable attributes: rebuild .lbr with adom-lbr 2.18.0 so MPN, MANUFACTURER and the distributor part numbers reach <technology> (DIGIKEY_PN 296-23118-2-ND, LCSC_PN C42737). The published library carried no attributes at all, so a BOM had nothing to buy from. Distributor PNs matched on exact MPN AND corroborating manufacturer.
