Is there a KiCad symbol and footprint for the LMC7221AIM?
Yes. The symbol is EasyEDA_Cloud:LMC7211AIM 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 LMC7221AIM?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LMC7221AIM datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LMC7221AIM?
JLCPCB lists it as part C2871061, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LMC7221AIM?
Parts like it in the library: the LM393D by onsemi, the LM393BID by Texas Instruments, the LM393DT by STMicroelectronics and the LM2903BID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
