Overview
The TL594IN is a DC DC Converter made by Texas Instruments in a PDIP-16 package with 16 pins. -40℃~+85℃@(TA) 2 300kHz 7V~40V Push-Pull PDIP-16 AC-DC Controllers and Regulators ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:TL594ID, from EasyEDA) and its footprint (Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1530260).

Is there a KiCad symbol and footprint for the TL594IN?
Yes. The symbol is EasyEDA_Cloud:TL594ID 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 TL594IN?
PDIP-16, with 16 pins. Its footprint is drawn on this page.
Where is the TL594IN datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the TL594IN?
JLCPCB lists it as part C1530260, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TL594IN?
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.
