The Texas Instruments SN65HVD73DGS is a full-duplex RS-422/RS-485 transceiver in a 10-VSSOP package, delivering a 20 Mbps data rate on a 3.3 V supply rail. The 70 mV receiver hysteresis provides clean edge detection on long cable runs without external filtering.
If your existing bus-side interface is 5 V, a level translator or a different transceiver variant is needed.
For long-term supply assurance, the base product number 65HVD73 covers multiple speed and package variants, making it easier to dual-source or migrate within the family if needed.
