Is there a KiCad symbol and footprint for the TL494IN?
Yes. The symbol is Regulator_Controller:TL494 and the footprint Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TL494IN?
DIP-16, with 16 pins. Its footprint is drawn on this page.
Where is the TL494IN datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the TL494IN?
JLCPCB lists it as part C110372, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TL494IN?
Parts like it in the library: the TL494CN by Texas Instruments, the UC3846N by Texas Instruments, the TL494IN by HGSEMI and the TL494CN(LX) by lingxingic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
