A homebrew 65c02s-based computer and custom operating system, with a handful of modern features.

Yes. The symbol is 74xx:74HC244 and the footprint Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
TSSOP-20, with 20 pins. Its footprint is drawn on this page.
Nexperia publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C6079, with 27,450 in stock; the sellers' links on this page open their listings.
