Questions

Is there a KiCad symbol and footprint for the SN74HC21D?

Yes. The symbol is EasyEDA_Cloud:SN74LS21N(XBLW) 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 SN74HC21D?

SOIC-14, with 14 pins. Its footprint is drawn on this page.

Where is the SN74HC21D datasheet?

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

Where can I order the SN74HC21D?

JLCPCB lists it as part C75398, with 1,203 in stock; the sellers' links on this page open their listings.

What can replace the SN74HC21D?

Parts like it in the library: the CD4093BM96 by Texas Instruments, the CD4078BM96 by Texas Instruments, the SN74LS21D by Texas Instruments and the CD4030BM96 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SN74HC21D?

2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
