Is there a KiCad symbol and footprint for the SN74HC244N?
Yes. The symbol is 74xx:74HC244 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 SN74HC244N?
DIP-20, with 20 pins. Its footprint is drawn on this page.
Where is the SN74HC244N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74HC244N?
JLCPCB lists it as part C2912, with 9 in stock; the sellers' links on this page open their listings.
What can replace the SN74HC244N?
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.
