Is there a KiCad symbol and footprint for the SN74LS33N?
Yes. The symbol is 74xx:74LS33 and the footprint Package_DIP:DIP-14_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN74LS33N?
PDIP-14, with 14 pins. Its footprint is drawn on this page.
Where is the SN74LS33N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74LS33N?
JLCPCB lists it as part C2869498, with 41 in stock; the sellers' links on this page open their listings.
What can replace the SN74LS33N?
Parts like it in the library: the CD4093BE by Texas Instruments, the CD4078BE by HGSEMI, the CD4093BE(XBLW) by XBLW and the CD4030BE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
