Is there a KiCad symbol and footprint for the SN74LS85D?
Yes. The symbol is 74xx:74LS85 and the footprint Package_SO:SOIC-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 SN74LS85D?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the SN74LS85D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74LS85D?
JLCPCB lists it as part C2653312, with 35 in stock; the sellers' links on this page open their listings.
What can replace the SN74LS85D?
