Questions

Is there a KiCad symbol and footprint for the 74ACT245M?

Yes. The symbol is 74xx:74HC245 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 74ACT245M?

SOIC-20-300mil, with 20 pins. Its footprint is drawn on this page.

Where is the 74ACT245M datasheet?

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

Where can I order the 74ACT245M?

JLCPCB lists it as part C5497, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 74ACT245M?

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.
