Is there a KiCad symbol and footprint for the FST3126D?
Yes. The symbol is EasyEDA_Cloud:74FST3126D and the footprint Package_SO:SO-14_3.9x8.65mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FST3126D?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the FST3126D datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FST3126D?
JLCPCB lists it as part C903752, with 0 in stock; the sellers' links on this page open their listings.
What can replace the FST3126D?
Parts like it in the library: the CD74HC243M96 by Texas Instruments, the MC74VHCT50AD by onsemi, the TC74HCT7007AF-ELF by Toshiba and the CD4041UBM96 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
