The 5 V supply is standard for legacy RS-485 networks; if your design runs a 3.3 V bus, note that the SN65HVD1176DG4 is not specified for 3.3 V logic-level inputs — the receiver thresholds and driver outputs are referenced to the 5 V rail.
TI lists the SN65HVD1176DG4 as an active product.
The SN65HVD1176DG4 is the RoHS-compliant (lead-free) version of the SN65HVD1176D. Electrically and functionally identical, the DG4 suffix indicates TI's green/RoHS plating finish.
Receiver thresholds and driver outputs are referenced to the 5 V rail, so 3.3 V logic levels may not meet the input high threshold or output low voltage. Use a 5 V-tolerant logic interface or a level shifter.
Within TI's own 65HVD1176 family, the SN65HVD1176D (non-RoHS) and SN65HVD1176DR (reel-packaged) are pin-compatible. For a second-source, consider the Maxim MAX3485 or Analog Devices ADM3485 families — verify pinout and supply voltage compatibility for your specific layout.
