RS-485/RS-422 full-duplex transceiver for 5V industrial buses
The 50 mV of receiver hysteresis provides noise margin on long cable runs, which is the spec that keeps data integrity in electrically noisy factory-floor environments.
That means Texas Instruments is still manufacturing it, no last-time-buy notice has been issued, and there is no forced redesign window. For a BOM line in a product with a multi-year service life, this removes the single-source obsolescence risk that haunts older RS-485 parts. The base product number is 65HVD1792, so any PCN or documentation updates will track under that root.
14-SOIC footprint — drop-in for the SOIC-14 RS-485 socket
If your existing design uses a 5V full-duplex transceiver in an SOIC-14, the SN65HVD1792TDREP is a direct mechanical and electrical fit, provided the pinout matches the 1/1 driver/receiver assignment.
