Questions
Is there a KiCad symbol and footprint for the 74HCT393D?
Yes. The symbol is Standard Logic:74393 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 74HCT393D?
SO-14, with 14 pins. Its footprint is drawn on this page.
Where is the 74HCT393D datasheet?
Nexperia publishes it: the Datasheet link on this page opens it.
Where can I order the 74HCT393D?
JLCPCB lists it as part C547641, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 74HCT393D?
Parts like it in the library: the 74HC4024D by Nexperia, the 74LV393D by Nexperia, the 74LV393D-Q100J by Nexperia and the NLV74HC393AD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
