Is there a KiCad symbol and footprint for the DM74LS166WMX?
Yes. The symbol is 74xx:74LS166 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 DM74LS166WMX?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the DM74LS166WMX datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the DM74LS166WMX?
JLCPCB lists it as part C3304326, with 0 in stock; the sellers' links on this page open their listings.
What can replace the DM74LS166WMX?
Parts like it in the library: the 74HC595D(XBLW) by XBLW, the TM74HC595 by TM, the SN74HC595D280 by GREENMICRO and the CD4094BDTR(XBLW) by XBLW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
