A healthy buffer shows a clean rail-to-rail digital signal matching the input on each channel. A failed buffer shows missing output, stuck-high or stuck-low, or distorted signal with overshoot\/undershoot.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I substitute another 6-pin dual buffer like the SN74LVC2G17?\u003c\/strong\u003e\u003cbr\u003eA: The SN74LVC2G17 is a Schmitt-trigger dual buffer with different timing characteristics. Always match the original part's logic family and propagation-delay spec — substitute parts with different timing can create skew that affects the hashboard chain communication.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Rework profile for SOT-363?\u003c\/strong\u003e\u003cbr\u003eA: Hot-air rework at 320°C with controlled airflow. Apply flux paste, preheat the board to 100°C, lift with tweezers, place fresh part with pin-1 orientation matching the silk-mark, reflow. The SOT-363 is small (1.6 × 1.6 × 1.0mm) and sensitive to thermal shock.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: AEC-Q100 vs standard part — does it matter?\u003c\/strong\u003e\u003cbr\u003eA: For mining-hashboard repair, the standard NL27WZ16DFT2G is the right part (matches OEM).
