Questions
Is there a KiCad symbol and footprint for the 74LVC257AD?
Yes. The symbol is 74xx:74LS257 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 74LVC257AD?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the 74LVC257AD datasheet?
Nexperia publishes it: the Datasheet link on this page opens it.
Where can I order the 74LVC257AD?
JLCPCB lists it as part C165622, with 46 in stock; the sellers' links on this page open their listings.
What can replace the 74LVC257AD?
Parts like it in the library: the 74HC4053M/TR by HGSEMI, the SN74HC138D by Texas Instruments, the 74HC138D by JSMSEMI and the MC74HC138AD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
