Is there a KiCad symbol and footprint for the HT12D?
Yes. The symbol is EasyEDA_Cloud:HT12D and the footprint Package_DIP:DIP-18_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT12D?
DIP-18, with 18 pins. Its footprint is drawn on this page.
Where is the HT12D datasheet?
Holtek Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the HT12D?
JLCPCB lists it as part C14360, with 0 in stock; the sellers' links on this page open their listings.
Which open-source boards use the HT12D?
7 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
