Questions
Is there a KiCad symbol and footprint for the SN74LS42N?
Yes. The symbol is 74xx:74LS42 and the footprint Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN74LS42N?
PDIP-16, with 16 pins. Its footprint is drawn on this page.
Where is the SN74LS42N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74LS42N?
JLCPCB lists it as part C1547352, with 9 in stock; the sellers' links on this page open their listings.
What can replace the SN74LS42N?
Parts like it in the library: the SN74HC138NED-GMIC by GREENMICRO, the 74HC138N by HGSEMI, the 74HC139N by HGSEMI and the 74HC238N by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
