The Texas Instruments SN65HVD37D is a full-duplex RS-422/RS-485 transceiver in a 14-SOIC package, rated for 20 Mbps signaling over balanced differential lines.
The 14-SOIC package is a rework-friendly footprint — a standard hot-air station with a fine nozzle lifts the part cleanly off the board without cooking adjacent passives, provided you pre-bake the reel at 125°C for 24 hours if the moisture-barrier bag has been breached (MSL 3).
Yes, the SN65HVD37D operates from 3V to 3.6V, so a 3.3V rail is right in the middle of its supply range. No 5V rail is needed.
The SN65HVD37D is the 14-SOIC package variant of the base SN65HVD37 transceiver. The 'D' suffix indicates the SOIC package; the electrical specifications (full duplex, 20 Mbps, 3V to 3.6V supply) are identical across the family.
Within the same 65HVD37 family, the SN65HVD37D is the 14-SOIC variant. Pin-compatible alternatives from other manufacturers include the MAX14850 or ADM2483, but verify the supply voltage range and data rate match your application — the SN65HVD37D runs at 20 Mbps from 3V to 3.6V.
