Is there a KiCad symbol and footprint for the DM74AS640N?

Yes. The symbol is EasyEDA_Cloud:SN74LS640M and the footprint Package_DIP:DIP-20_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 DM74AS640N?

PDIP-20, with 20 pins. Its footprint is drawn on this page.

Where is the DM74AS640N datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the DM74AS640N?

JLCPCB lists it as part C3587312, with 0 in stock; the sellers' links on this page open their listings.

What can replace the DM74AS640N?

Parts like it in the library: the SN74HC244N(LX) by lingxingic, the AIP74HC540DA20.TB by Wuxi I-core Elec, the AIP74HC541DA20.TB by Wuxi I-core Elec and the 74HC244N-HX by ZHHXDZ. Check their datasheets: a part that fits the footprint may still differ in its ratings.
