Questions
Is there a KiCad symbol and footprint for the TL494CD?
Yes. The symbol is Regulator_Controller:TL494 and the footprint Package_SO:SOIC-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 TL494CD?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the TL494CD datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the TL494CD?
JLCPCB lists it as part C889954, with 84 in stock; the sellers' links on this page open their listings.
What can replace the TL494CD?
Parts like it in the library: the NCP1034D by onsemi, the SG3525A(LX) by lingxingic, the TL494BD by onsemi and the MIC2182-3.3YM by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
