Questions

Is there a KiCad symbol and footprint for the 74HC574D?

Yes. The symbol is 74xx:74LS574 and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 74HC574D?

SOP-20L, with 20 pins. Its footprint is drawn on this page.

Where is the 74HC574D datasheet?

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

Where can I order the 74HC574D?

JLCPCB lists it as part C52140410, with 2,426 in stock; the sellers' links on this page open their listings.

What can replace the 74HC574D?

Parts like it in the library: the SN74HC374DWE4 by Texas Instruments, the SN74HCT374DWG4 by Texas Instruments, the SN74HC74DR(LX) by lingxingic and the 74HC74D by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the 74HC574D?

66 boards in 33 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
