74LS194ADC — active parallel in/out shift register
It belongs to the 74LS logic family, operating from a standard 5 V supply. Designated as active in production, this part is available for current BOM lines without end-of-life risk. The Bulk package suits through-hole assembly or tube-fed pick-and-place handling.
Bulk package and board integration
Supplied in Bulk format, the 74LS194ADC ships as loose tubes or trays — no tape-and-reel. For reflow assembly, check the moisture-sensitivity level (MSL) on the part marking; if unmarked, treat as MSL 1 (no bake required) per JEDEC standard for hermetic or cavity packages. The through-hole DIP footprint is standard 0.100-inch pitch, 16 pins. No thermal pad or exposed paddle — standard socket or solder-wave profile applies.
