Questions

Is there a KiCad symbol and footprint for the LM555CM?

Yes. The symbol is Timer:LM555xM and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM555CM?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM555CM datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM555CM?

JLCPCB lists it as part C1520196, with 95 in stock; the sellers' links on this page open their listings.

What can replace the LM555CM?

Parts like it in the library: the NE555D by Texas Instruments, the NE555DR by UMW, the NE555DR-JSM by JSMSEMI and the LM555CM/TR by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM555CM?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
