Overview
The 74LS170PC is a shift Register made by Texas Instruments in a PDIP-16 package with 16 pins. 0℃~+70℃ 1 20uA 35ns@5V,15pF 4.75V~5.25V 74LS Output enable PDIP-16 Shift Registers.
PCBKit's library has its KiCad symbol (74xx:74LS170, from KiCad's library) and its footprint (Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3301292). 1 open-source board in 1 repository on GitHub use it.
