Is there a KiCad symbol and footprint for the NE556?
Yes. The symbol is Timer:NE556 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 NE556?
SOP-14, with 14 pins. Its footprint is drawn on this page.
Where is the NE556 datasheet?
GR publishes it: the Datasheet link on this page opens it.
Where can I order the NE556?
JLCPCB lists it as part C18164404, with 538 in stock; the sellers' links on this page open their listings.
What can replace the NE556?
Parts like it in the library: the NA556D by Texas Instruments, the NE556D by Texas Instruments, the NE556DRG by HANSCHIP semiconductor and the NE556DR-MS by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the NE556?
31 boards in 29 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
