Is there a KiCad symbol and footprint for the FST3253M?
Yes. 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 FST3253M?
SOIC-16, with 5 pins. Its footprint is drawn on this page.
Where is the FST3253M datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FST3253M?
JLCPCB lists it as part C3234428, with 0 in stock; the sellers' links on this page open their listings.
What can replace the FST3253M?
Parts like it in the library: the 74HC138D by Nexperia, the EM74HC138D by EnergyMath, the CD4028BM(LX) by lingxingic and the CJ74HC157AEN by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the FST3253M?
19 boards in 15 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
