Questions

Is there a KiCad symbol and footprint for the ULN2004A?

Yes. The symbol is Transistor_Array:ULN2004A and the footprint Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ULN2004A?

DIP-16, with 16 pins. Its footprint is drawn on this page.

Where is the ULN2004A datasheet?

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

Where can I order the ULN2004A?

JLCPCB lists it as part C182544, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ULN2004A?

Parts like it in the library: the ULN2003AN(XBLW) by XBLW, the ULN2003A by STMicroelectronics, the ULN2003AN by Texas Instruments and the ULN2003L-D16-T by UTC. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ULN2004A?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
