Questions

Is there a KiCad symbol and footprint for the SN74HC14D?

Yes. The symbol is 74xx:74HC14 and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74HC14D?

SOIC-14, with 14 pins. Its footprint is drawn on this page.

Where is the SN74HC14D datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the SN74HC14D?

JLCPCB lists it as part C6820, with 183,583 in stock; the sellers' links on this page open their listings.

What can replace the SN74HC14D?

Parts like it in the library: the MC14584BD by onsemi, the MC14106BD by onsemi, the CD4007UBM/TR by HGSEMI and the RS6G14XP by Jiangsu RUNIC Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
