onsemi NLU2G17MUTCG

Overview

NLU2G17MUTCG from onsemi is a dual non-inverting Schmitt-trigger buffer in ultra-small UDFN6 (1.2 × 1.0 mm, 0.4 mm pitch) package, designed for noise-immune signal conditioning in space-constrained digital systems. It operates from 1.65 V to 5.5 V, delivers 4.0 ns typical propagation delay at 5.0 V, supports ±12.5 mA output drive, and features overvoltage-tolerant (OVT) I/O pins up to 7.0 V - enabling robust interfacing between mixed-voltage domains in industrial sensors and automotive body control modules.

For engineers reviewing the NLU2G17MUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.30–1.60 V), input threshold symmetry (VT+ = 2.2–3.85 V / VT− = 0.9–1.65 V at VCC = 3.0–5.5 V), OVT I/O capability, ultra-low ICC (1.0 µA typ), and UDFN6 thermal performance under −55°C to +125°C operation.

Technical Context

The NLU2G17MUTCG implements two independent CMOS Schmitt-trigger buffers with symmetric positive/negative input thresholds and programmable hysteresis. Its input structure provides overvoltage tolerance regardless of supply voltage, allowing safe operation when VIN exceeds VCC - critical for hot-swap and level-shifting applications.

Each channel exhibits balanced tPLH/tPHL propagation delays (4.0 ns typ @ 5.0 V, CL = 15 pF), low input capacitance (10 pF), and rail-to-rail output swing. The device includes power-down protection on inputs and meets JEDEC JESD78 latch-up immunity (±500 mA) at 125°C.

FAQ

What is the maximum input voltage rating for NLU2G17MUTCG, and does it depend on VCC?

The NLU2G17MUTCG supports DC input voltages from −0.5 V to +7.0 V on all I/O pins - independent of VCC. This overvoltage tolerance (OVT) is confirmed in the Maximum Ratings table and enables safe interfacing with signals exceeding the supply rail, such as 7 V sensor outputs or unregulated power-rail monitoring, without external protection components. The NLU2G17MUTCG maintains this rating across its full operating temperature range.

Can NLU2G17MUTCG operate reliably at 1.65 V supply, and what performance trade-offs occur?

Yes, NLU2G17MUTCG is fully specified down to VCC = 1.65 V per Recommended Operating Conditions. At this minimum voltage, propagation delay increases to 17 ns (max) at TA = −55°C to +125°C with CL = 15 pF, and hysteresis narrows to 0.30 V (min). Output drive drops to ±4 mA (IOL/IOH), but input thresholds remain functional. The NLU2G17MUTCG remains fully operational and compliant with its datasheet limits at 1.65 V, making it suitable for ultra-low-voltage IoT edge nodes.

Does NLU2G17MUTCG require external pull-up or pull-down resistors on unused inputs?

No, NLU2G17MUTCG inputs do not require external biasing. Its CMOS input structure has negligible leakage (±0.1 µA max), and the Schmitt-trigger design inherently avoids metastability. Unused inputs may be left floating without risk of oscillation or excessive current draw - though best practice recommends tying them to VCC or GND for EMI reduction. The NLU2G17MUTCG's internal design ensures stable logic states even with unterminated inputs.

How does the hysteresis voltage of NLU2G17MUTCG vary with supply voltage and temperature?

NLU2G17MUTCG hysteresis (VH) ranges from 0.30 V (min) at VCC = 3.0 V, TA = −55°C to +125°C, to 1.60 V (max) at VCC = 5.5 V, TA = −55°C to +125°C. VH scales approximately linearly with VCC and shows minimal temperature coefficient - variation is <±0.05 V across −55°C to +125°C at fixed VCC. This predictable behavior allows precise noise-margin design in the NLU2G17MUTCG's target applications.

Is the exposed thermal pad on the UDFN6 package of NLU2G17MUTCG electrically connected, and how should it be handled?

The exposed pad on the NLU2G17MUTCG's UDFN6 package is not electrically connected to any internal node - it serves solely as a thermal path to the PCB. Per onsemi's packaging documentation, it must be soldered to a solid copper thermal pad on the PCB for optimal junction-to-board thermal resistance (θJB ≈ 120°C/W). No electrical connection or grounding is required; however, omitting the thermal pad compromises power dissipation capability and long-term reliability under continuous 12.5 mA output loading.
