Is there a KiCad symbol and footprint for the LM393LS8?
Yes. The symbol is Comparator:LM393 and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM393LS8?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM393LS8 datasheet?
TECH PUBLIC publishes it: the Datasheet link on this page opens it.
Where can I order the LM393LS8?
JLCPCB lists it as part C48543200, with 2,150 in stock; the sellers' links on this page open their listings.
What can replace the LM393LS8?
Parts like it in the library: the LM2903DR by UMW, the LM393ADR by UMW, the LM393 by MSKSEMI and the LM393DRG by HANSCHIP semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM393LS8?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
