This is the sweet spot for factory-floor RS-485 networks running Modbus RTU or Profibus DP at 115.2 kbaud — fast enough for most sensor polling loops, slow enough that cable capacitance and stub length aren't critical. If your application needs 1 Mbps or higher, this part isn't the right fit; look at the SN65HVD1786 or SN65HVD1787 family members instead. ## Rework note: 8-SOIC is a friend under the hot air The body's low thermal mass means it reflows cleanly with a standard hot-air station — just preheat the board to avoid cold joints on the ground pad. No exposed pad to solder, no hidden leads.","metaTitle":"SN65HVD1785DR RS-485 Transceiver, 115 kbps, 8-SOIC","metaDescription":"Texas Instruments SN65HVD1785DR half-duplex RS-485 transceiver. 115 kbps data rate, 4.5V–5.5V supply, 8-SOIC package.
