Is there a KiCad symbol and footprint for the LM556CM?
Yes. The symbol is Timer:LM556 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 LM556CM?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the LM556CM datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the LM556CM?
JLCPCB lists it as part C17285564, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM556CM?
Parts like it in the library: the NA556D by Texas Instruments, the MC14541BD by onsemi, the NE556D by Texas Instruments and the NE556DRG by HANSCHIP semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
