Is there a KiCad symbol and footprint for the SN74128D?
Yes. The symbol is 74xx_IEEE:74128 and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN74128D?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the SN74128D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74128D?
JLCPCB lists it as part C2878602, with 16 in stock; the sellers' links on this page open their listings.
What can replace the SN74128D?
Parts like it in the library: the CD4093BM96 by Texas Instruments, the CD4078BM96 by Texas Instruments, the SN74LS21D by Texas Instruments and the CD4030BM96 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
