Is there a KiCad symbol and footprint for the 74ACT244SC?
Yes. The symbol is 74xx:74HC244 and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 74ACT244SC?
SOIC-20-300mil, with 20 pins. Its footprint is drawn on this page.
Where is the 74ACT244SC datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the 74ACT244SC?
JLCPCB lists it as part C906682, with 1 in stock; the sellers' links on this page open their listings.
What can replace the 74ACT244SC?
Parts like it in the library: the 74HC245D by Nexperia, the 74HCT244D by Nexperia, the 74HCT245D by Nexperia and the SN74HC244DW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the 74ACT244SC?
16 boards in 9 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
