Is there a KiCad symbol and footprint for the 74HC112D?
Yes. The symbol is 74xx:74LS112 and the footprint Package_SO:SO-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 74HC112D?
SO-16, with 16 pins. Its footprint is drawn on this page.
Where is the 74HC112D datasheet?
Nexperia publishes it: the Datasheet link on this page opens it.
Where can I order the 74HC112D?
JLCPCB lists it as part C8167, with 1 in stock; the sellers' links on this page open their listings.
What can replace the 74HC112D?
Parts like it in the library: the SN74LS112N(XBLW) by XBLW, the SN74HC273N(XBLW) by XBLW, the SN74HC112N(XBLW) by XBLW and the TC74HC273APF by Toshiba. Check their datasheets: a part that fits the footprint may still differ in its ratings.
