Questions

Is there a KiCad symbol and footprint for the SN74HC640N?

Yes. The symbol is EasyEDA_Cloud:SN74ALS1640AN and the footprint Package_DIP:DIP-20_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74HC640N?

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

Where is the SN74HC640N datasheet?

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

Where can I order the SN74HC640N?

JLCPCB lists it as part C1548356, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SN74HC640N?

Parts like it in the library: the 74HC541D by GR, the SN74HC240N(XBLW) by XBLW, the SN74HC244N(XBLW) by XBLW and the 74HC245N by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
