Overview
The LM393AD is a comparator made by Texas Instruments in a SOIC-8 package with 8 pins. -18V~-2V、2V~18V 0℃~+70℃ 1.3us 100nA 1mA 2 2V~36V 2mV 36V 5nA Open-drain TTL SOIC-8 Comparators ROHS.
PCBKit's library has its KiCad symbol (Comparator:LM393, from KiCad's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 34,664 are in stock at JLCPCB (part C30394). 3 open-source boards in 3 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the LM393AD?
Yes. The symbol is Comparator:LM393 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 LM393AD?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM393AD datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM393AD?
JLCPCB lists it as part C30394, with 34,664 in stock; the sellers' links on this page open their listings.
What can replace the LM393AD?
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.
Which open-source boards use the LM393AD?
3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
