Questions
Is there a KiCad symbol and footprint for the ST3243EB?
Yes. The symbol is EasyEDA_Cloud:MAX3245EEWI+ and the footprint Package_SO:TSSOP-28_4.4x9.7mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ST3243EB?
TSSOP-28, with 28 pins. Its footprint is drawn on this page.
Where is the ST3243EB datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ST3243EB?
JLCPCB lists it as part C2971553, with 9 in stock; the sellers' links on this page open their listings.
What can replace the ST3243EB?
Parts like it in the library: the SP3243EBEY-L/TR by MaxLinear, the GM3243ETA by GATEMODE, the SP336EEY-L/TR by MaxLinear and the MAX3243ECPW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
