Questions

Is there a KiCad symbol and footprint for the 74HC73D?

Yes. The symbol is 74xx:74LS73 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 74HC73D?

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

Where is the 74HC73D datasheet?

Nexperia publishes it: the Datasheet link on this page opens it.

Where can I order the 74HC73D?

JLCPCB lists it as part C148207, with 2,483 in stock; the sellers' links on this page open their listings.

What can replace the 74HC73D?

Parts like it in the library: the 74HC73D-Q100J by Nexperia, the 74HC73D/C118 by Nexperia, the 74HC73D/C4118 by Nexperia and the SN74LS175N(XBLW) by XBLW. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the 74HC73D?

7 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
