Overview
The SN74ALS166D is a shift Register made by Texas Instruments in a SOIC-16 package with 16 pins. 0℃~+70℃ 1 4.5V~5.5V 74ALS 8 Parallel or Serial to Serial Push-Pull SOIC-16 Shift Registers ROHS.
PCBKit's library has its KiCad symbol (74xx:74LS166, from KiCad's library) and its footprint (Package_SO:SO-16_3.9x9.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3304330).
