Trilobyte-CPU/8-bit-computer
A DIY 8-bit computer built mostly with discrete logic chips

The CD4072BE is a logic Gate made by Texas Instruments in a DIP-14 package with 14 pins. -55℃~+125℃ 1.5V~4V 1uA 2 3.4mA 3.4mA 3.5V~11V 3V~18V 4 4.95V、9.95V、14.95V 4000B Series 50mV 90ns@15V,50pF OR Gate DIP-14 Logic Gates ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CD4072BE, from EasyEDA) and its footprint (Package_DIP:DIP-14_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. 43 are in stock at JLCPCB (part C5330). 5 open-source boards in 3 repositories on GitHub use it.

The symbol is EasyEDA_Cloud:CD4072BE and the footprint Package_DIP:DIP-14_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
DIP-14, with 14 pins. Its footprint is drawn on this page.
Texas Instruments publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C5330, with 43 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the CD4093BE by Texas Instruments, the CD4078BE by HGSEMI, the CD4093BE(XBLW) by XBLW and the CD4030BE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
5 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
