NL27WZ16DFT2G Double Buffer for Innosilicon Hashboard

NL27WZ16DFT2G Dual Non-Inverting Buffer | onsemi High-Performance Driver for Innosilicon Hash Board

The NL27WZ16DFT2G is a high-performance dual non-inverting buffer / line driver from onsemi (ON Semiconductor) — the chain-buffer IC used on Innosilicon hashboards to drive ASIC chip clock and data signals between domains with different transmission characteristics. The chip temporarily buffers data flowing between hashing-ASIC chain segments, ensuring clean signal integrity across the full chain length even when individual ASIC chips present mismatched input impedances.

Per onsemi's NL27WZ16 datasheet, the buffer offers a wide 1.65V to 5.5V supply voltage range, push-pull (totem-pole) output stage, and 2 independent buffer channels in a single package. Static supply current is just 10 μA typical, and propagation delay is 4.6 ns at 3.3V or 3.8 ns at 5V — fast enough to drive the multi-MHz clock distribution typical of modern hashing-ASIC chains without introducing meaningful skew across the buffered links.

Where the NL27WZ16DFT2G Fits in Hashboard Repair

• Innosilicon hashboard chain-buffer position — clock and data signal regeneration between ASIC chip groups.
• Hashboard chain-detection failure — when the controller can't see chips beyond a certain position on the chain, a failed buffer is a common root cause.
• Intermittent hashrate drop traced to signal-integrity issues after thermal warm-up.
• Repair-bench standard chip for any chain-buffer footprint on Innosilicon-family hashboards (T1, T2, T3, A4, A6, etc.).
• Bitaxe-type small-miner hashboards using similar signal-chain topology.

NL27WZ16DFT2G Specifications

FAQ — NL27WZ16DFT2G Dual Buffer

Q: How do I confirm a failed NL27WZ16DFT2G on a hashboard?
A: Probe the buffer's output pins with a 100MHz scope while the hashboard is in self-test. 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.

Q: Can I substitute another 6-pin dual buffer like the SN74LVC2G17?
A: 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.

Q: Rework profile for SOT-363?
A: 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.

Q: AEC-Q100 vs standard part — does it matter?
A: For mining-hashboard repair, the standard NL27WZ16DFT2G is the right part (matches OEM). The AEC-Q100 "-Q" variant is qualified for automotive use and identical electrically; either works in a pinch.

Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com for tape-and-reel quantities.
