The 74HC164 is a shift Register made by GR in a SOP-14 package with 14 pins. 0℃~+70℃ 1 24ns@5V,16pF 2V~6V 74HC 8 Serial-to-Parallel SOP-14 Shift Registers ROHS.
PCBKit's library has its KiCad symbol (74xx:74HC164, from KiCad's library) and its footprint (Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, from KiCad's library), ready for a KiCad board. 49,970 are in stock at JLCPCB (part C18164492). 82 open-source boards in 62 repositories on GitHub use it.
