Is there a KiCad symbol and footprint for the 74HC259D?
Yes. The symbol is 74xx:74LS259 and the footprint Package_SO:SOIC-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 74HC259D?
SOP-16L, with 16 pins. Its footprint is drawn on this page.
Where is the 74HC259D datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the 74HC259D?
JLCPCB lists it as part C52140406, with 1,835 in stock; the sellers' links on this page open their listings.
What can replace the 74HC259D?
Parts like it in the library: the CD4044BDR by Texas Instruments, the CD4043NS16ARDQ by GR, the SN74LS279ADR(LX) by lingxingic and the CD4042BD by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the 74HC259D?
10 boards in 8 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
