Is there a KiCad symbol and footprint for the SN74LVC125AD?
Yes. The symbol is 74xx:74LVC125 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 SN74LVC125AD?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the SN74LVC125AD datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74LVC125AD?
JLCPCB lists it as part C7661, with 3,613 in stock; the sellers' links on this page open their listings.
What can replace the SN74LVC125AD?
Parts like it in the library: the 74HC126D by Nexperia, the 74HC125D by Toshiba, the 74HC126D by Toshiba and the 74AHC125D by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SN74LVC125AD?
11 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
