TI lists the SN65HVD11DRG4 as Active. No last-time-buy has been announced, no PCN flags a pending phase-out. The DRG4 suffix indicates a lead-free, RoHS-compliant finish, so it passes the usual environmental compliance checks for EU and global markets.
They are not drop-in replacements without a supply rail change. The SN65HVD11DRG4 is the 3.3 V counterpart in TI's 3.3 V RS-485 family, not a pin-for-pin substitute for the 5 V SN75HVD10.
The SN65HVD11DRG4 is rated for 10 Mbps, while the SN65HVD12DRG4 is rated for 1 Mbps. Both are half-duplex RS-485/RS-422 transceivers in 8-SOIC with the same pinout and supply range. The speed difference is the deciding factor: pick the 11 for high-throughput links, the 12 for longer cable runs where slower edge rates reduce reflections.
