Questions

Is there a KiCad symbol and footprint for the SN74HC27DB?

Yes. The symbol is 74xx:74LS27 and the footprint Package_SO:SSOP-14_5.3x6.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74HC27DB?

SSOP-14-208mil, with 14 pins. Its footprint is drawn on this page.

Where is the SN74HC27DB datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the SN74HC27DB?

JLCPCB lists it as part C2859592, with 695 in stock; the sellers' links on this page open their listings.

What can replace the SN74HC27DB?

Parts like it in the library: the 74HC21DB,118-NEX by Nexperia, the 74ABT20DB by NXP Semiconductors, the BU4011BFV-E2 by ROHM Semiconductor and the BU4093BFV-E2 by ROHM Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
