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?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the TL494CD?

JLCPCB lists it as part C19882, with 38,765 in stock; the sellers' links on this page open their listings.

What can replace the TL494CD?

Parts like it in the library: the TL494ID by Texas Instruments, the SG3525AP(UMW) by UMW, the NCP1034D by onsemi and the TL494 by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the TL494CD?

3 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
