Questions
Is there a KiCad symbol and footprint for the ST3222B?
Yes. The symbol is EasyEDA_Cloud:MAX3222EEUP_V+T and the footprint Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ST3222B?
TSSOP-20, with 20 pins. Its footprint is drawn on this page.
Where is the ST3222B datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ST3222B?
JLCPCB lists it as part C283494, with 97 in stock; the sellers' links on this page open their listings.
What can replace the ST3222B?
Parts like it in the library: the SP3223EEY-L/TR by MaxLinear, the AZ75232GTR-G1 by Diodes Incorporated, the GD75232PW by Texas Instruments and the MAX3222EIPW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
