Questions
Is there a KiCad symbol and footprint for the U74HC245G?
Yes. The symbol is 74xx:74HC245 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.
What package is the U74HC245G?
TSSOP-20, with 20 pins. Its footprint is drawn on this page.
Where is the U74HC245G datasheet?
UTC publishes it: the Datasheet link on this page opens it.
Where can I order the U74HC245G?
JLCPCB lists it as part C7509614, with 50 in stock; the sellers' links on this page open their listings.
What can replace the U74HC245G?
Parts like it in the library: the 74LVC245APW,118 by Nexperia, the SN74AHCT541PW by Texas Instruments, the SN74ACT244PW by Texas Instruments and the 74VHC245PW by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
