Questions

Is there a KiCad symbol and footprint for the SN74LS253N?

Yes. The symbol is 74xx:74LS253 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 SN74LS253N?

PDIP-16, with 16 pins. Its footprint is drawn on this page.

Where is the SN74LS253N datasheet?

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

Where can I order the SN74LS253N?

JLCPCB lists it as part C1547277, with 10 in stock; the sellers' links on this page open their listings.

What can replace the SN74LS253N?

Parts like it in the library: the SN7447ANE4 by Texas Instruments, the SN74LS251NG4 by Texas Instruments and the XD22100 by XINLUDA. Check their datasheets: a part that fits the footprint may still differ in its ratings.
