Is there a KiCad symbol and footprint for the 74LS174DC?
Yes. The symbol is EasyEDA_Cloud:SN74ALS175NS and the footprint EasyEDA_Cloud:SOIC-16_L9.9-W3.9-P1.27-LS6.0-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
Where is the 74LS174DC datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the 74LS174DC?
JLCPCB lists it as part C3825724, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 74LS174DC?
Parts like it in the library: the 74HC273D by Nexperia, the 74HC76S by GR, the AIP74HC574SA20.TR by Wuxi I-core Elec and the CD4027BE by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the 74LS174DC?
80 boards in 66 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
