Overview
The LP311D is a comparator made by Texas Instruments in a SOIC-8 package with 8 pins. 0℃~+70℃ 1 1.2us 100nA 3.5V~30V 300uA 7.5mV Offset voltage nulling、Enable/shutdown function TTL SOIC-8 Comparators ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:LP311DR, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 102 are in stock at JLCPCB (part C354102).

Is there a KiCad symbol and footprint for the LP311D?
Yes. The symbol is EasyEDA_Cloud:LP311DR 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 LP311D?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LP311D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LP311D?
JLCPCB lists it as part C354102, with 102 in stock; the sellers' links on this page open their listings.
What can replace the LP311D?
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.
