TI has announced end-of-life for this specific ordering code, meaning there is a final purchase window before the part becomes permanently unavailable from the factory. After that date, supply shifts entirely to the independent surplus and broker channel. For a BOM line that still needs this exact code, the procurement action is to secure inventory now or qualify a replacement before the last-buy deadline passes.

Frequently asked questions
Is SN65HVD11QD obsolete?
Yes, the SN65HVD11QD has been placed in Last Buy status by Texas Instruments. It is not yet fully discontinued, but the final purchase window is open. After the last-buy date, availability will be limited to the surplus channel. Sourcing through independent distribution is possible now and after the LTB closes.
What are the alternatives for SN65HVD11QD?
The closest pin-compatible alternative is the SN65HVD11QDR, which is the same transceiver in tape-and-reel packaging. For a drop-in replacement with identical electrical specs, that is the direct cross. If a broader second source is needed, any 3.3V half-duplex RS-485 transceiver in an SOIC-8 with 10 Mbps capability can be considered, but pinout and receiver hysteresis should be verified against the TI footprint.
Is SN65HVD11QD compatible with 3.3V systems?
No level shifting is needed for the driver inputs or receiver outputs when the MCU or FPGA also runs at 3.3V.
