Is there a KiCad symbol and footprint for the LM3445MX?
Yes. The symbol is EasyEDA_Cloud:LM3445MX_NOPB 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 LM3445MX?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the LM3445MX datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM3445MX?
JLCPCB lists it as part C2678746, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM3445MX?
Parts like it in the library: the ULN2002M/TR by HGSEMI, the RSC6105S by REASUNOS, the TM1809(TA1515) by TM and the WS2801S by Worldsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
