This means the output transistor pulls the line to ground; an external pull-up resistor to the supply rail defines the logic-high voltage level. This limits the part to indoor, temperature-controlled environments — not suitable for automotive or outdoor enclosures without additional thermal management. ## 14-SOIC footprint and board integration The tube delivery means the parts arrive in anti-static tubes, not tape-and-reel — factor this into pick-and-place setup if you're running high-volume reels. Six independent buffer elements in one package saves board space compared to six discrete transistors or single-gate parts. Each element has one input and one output; the open-collector output allows wired-OR connections on a shared bus without contention. The part belongs to the 7400 series, a long-running logic family.","metaTitle":"SN7407D Texas Instruments Buffer, Open Collector, 14-SOIC","metaDescription":"SN7407D hex non-inverting buffer with open-collector outputs. 4.75V–5.25V supply, 40 mA sink per channel.
