MNT VA2000, an Open Source Amiga 2/3/4000 Graphics Card (Zorro II/III), written in Verilog

The 74LS04PC is an inverter made by onsemi in a PDIP-14 package with 14 pins. 0℃~+70℃ 4.75V~5.25V 6 6.6mA 74LS PDIP-14 Inverters.
PCBKit's library has its KiCad symbol (74xx:74LS04, from KiCad's library) and its footprint (Package_DIP:DIP-14_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3272431). 513 open-source boards in 331 repositories on GitHub use it.
