Is there a KiCad symbol and footprint for the CD4043BDR?
Yes. The symbol is EasyEDA_Cloud:CD4043BEE4 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CD4043BDR?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the CD4043BDR datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the CD4043BDR?
JLCPCB lists it as part C40131, with 922 in stock; the sellers' links on this page open their listings.
What can replace the CD4043BDR?
Parts like it in the library: the CD4044BDR by Texas Instruments, the CD4043NS16ARDQ by GR, the 74HC259D by MDD and the SN74LS279ADR(LX) by lingxingic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CD4043BDR?
7 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
