Is there a KiCad symbol and footprint for the TL3843BD?
Yes. The symbol is EasyEDA_Cloud:TL2845BD and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TL3843BD?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the TL3843BD datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the TL3843BD?
JLCPCB lists it as part C544295, with 76 in stock; the sellers' links on this page open their listings.
What can replace the TL3843BD?
Parts like it in the library: the UC2843ADTR by Texas Instruments, the UC2844BD by onsemi, the UC3843DTR by Texas Instruments and the TL2843BQDRQ1 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
