Questions

Is there a KiCad symbol and footprint for the THVD2450D?

Yes. The symbol is EasyEDA_Cloud:MS2111 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the THVD2450D?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the THVD2450D datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the THVD2450D?

JLCPCB lists it as part C2672621, with 34,179 in stock; the sellers' links on this page open their listings.

What can replace the THVD2450D?

Parts like it in the library: the SP3485EN-L/TR by MaxLinear, the SP485EEN-L/TR by MaxLinear, the SN75176BD by Texas Instruments and the MAX485ESA+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the THVD2450D?

4 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
