Is there a KiCad symbol and footprint for the SN74LS166D?
Yes. The symbol is 74xx:74LS166 and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN74LS166D?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the SN74LS166D datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the SN74LS166D?
JLCPCB lists it as part C3301527, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SN74LS166D?
Parts like it in the library: the 74HC165D by Nexperia, the HTC74HC595S-R by HITENX, the SN74LS165DTR(XBLW) by XBLW and the MC74HC595ADR by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
