Is there a KiCad symbol and footprint for the SN74AS245DW?
Yes. The symbol is EasyEDA_Cloud:SN74ALS1640AN 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 SN74AS245DW?
SOIC-20-300mil, with 20 pins. Its footprint is drawn on this page.
Where is the SN74AS245DW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74AS245DW?
JLCPCB lists it as part C1548409, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SN74AS245DW?
Parts like it in the library: the 74LVC245AD by Nexperia, the 74LVC244AD by Nexperia, the 74HC240D by Nexperia and the SN74AHC244DW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
