Product details
Overview
NLU3G14MUTAG from onsemi is a triple Schmitt-trigger inverter IC designed for noise-immune signal conditioning in space-constrained digital systems. It features 4.0 ns typical propagation delay at 5.0 V, ±12.5 mA output drive, overvoltage-tolerant (OVT) I/O pins rated to 7.0 V, and operates across −55°C to +125°C. It is used to square slow-rising waveforms in sensor interface and clock clean-up circuits.
For engineers reviewing the NLU3G14MUTAG datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.30–1.60 V), ultra-small UDFN8 package footprint (1.6 × 1.0 mm), input threshold symmetry (VT+ = 3.50 V / VT− = 1.65 V at 5.5 V), and Pb-free compliance per JEDEC J-STD-020.
Technical Context
The NLU3G14MUTAG implements three independent Schmitt-trigger inverters in a single CMOS gate array, each with asymmetric hysteresis (ΔVT = VH = 0.30–1.60 V depending on VCC). Its OVT architecture allows safe interfacing with signals exceeding VCC-up to 7.0 V-without external clamping diodes.
It supports rail-to-rail input operation (0–5.5 V) and delivers balanced tPLH/tPHL delays (4.0–12.8 ns) under 15–50 pF loads. The device includes power-down protection on all inputs and meets Level 1 moisture sensitivity per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.0 ns typical at VCC = 5.0 V, CL = 15 pF - enables high-speed waveform shaping in timing-critical interfaces |
| Hysteresis Voltage (VH) | 0.30–1.60 V range across VCC = 3.0–5.5 V - provides configurable noise margin against EMI in industrial sensor nodes |
| Input Thresholds (VT+, VT−) | VT+ = 3.50 V, VT− = 1.65 V at VCC = 5.5 V - ensures robust switching for slowly ramping analog-derived logic signals |
| Overvoltage Tolerance | ±7.0 V on all I/O pins regardless of VCC - eliminates need for external level-shifting or clamping in mixed-voltage systems |
| Supply Range | 1.65–5.5 V DC - supports direct integration with 1.8 V, 3.3 V, and 5 V logic domains without voltage translation |
| Output Drive | ±12.5 mA sink/source - sufficient to directly drive LED indicators or small capacitive loads (<50 pF) |
| Quiescent Current | 1.0 µA typical at VCC = 5.5 V - enables low-power always-on monitoring in battery-backed subsystems |
Pinout & Package
Package: UDFN8 (1.6 × 1.0 mm, 0.4 mm pitch), case 517BY, Pb-free, moisture sensitivity Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A2 | Input of second Schmitt inverter - accepts overvoltage-tolerant digital or analog-sourced signals up to 7.0 V |
| 2 | IN A1 | Input of first Schmitt inverter - shares same OVT and hysteresis characteristics as all inputs |
| 3 | OUT Y3 | Output of third Schmitt inverter - actively drives high/low with ±12.5 mA capability and rail-to-rail swing |
| 4 | OUT Y2 | Output of second Schmitt inverter - electrically isolated from other outputs; no internal cross-talk |
| 5 | GND | Dedicated ground reference - must be connected to system ground plane for stable noise immunity and thermal dissipation |
| 6 | IN A3 | Input of third Schmitt inverter - identical electrical behavior to Pins 1 and 2; supports asynchronous signal conditioning |
| 7 | OUT Y1 | Output of first Schmitt inverter - complements IN A1 with hysteresis-based edge sharpening |
| 8 | VCC | Positive supply rail - powers all three inverters; decoupling capacitor (0.1 µF) required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent hysteresis inverters in one die - reduces board area vs. discrete solutions and eliminates inter-device skew |
| Overvoltage-tolerant I/O | All pins withstand −0.5 V to +7.0 V regardless of VCC - enables direct connection to legacy 5 V buses or sensor outputs without level shifters |
| Ultra-small UDFN8 footprint | 1.6 × 1.0 mm outline with 0.4 mm pitch - fits into dense portable electronics such as wearables and IoT edge nodes |
| Balanced propagation delays | tPLH and tPHL match within ±1 ns at 5 V - preserves duty cycle integrity when cleaning PWM or encoder signals |
| Pb-free and RoHS-compliant | Meets JEDEC J-STD-020 MSL Level 1 - supports lead-free reflow assembly without special baking or handling |
Applications
| Industrial Sensor Interface | Low-Power Clock Clean-Up |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Single-channel only; 3.5 ns delay at 3.3 V; no OVT - requires external clamping above VCC | Lacks triple integration and overvoltage tolerance - unsuitable for mixed-voltage or high-noise sensor front-ends | Select when only one inverter is needed and system voltage is strictly ≤ VCC; lower cost but higher system-level component count |
| MC74VHC1GT14DTT1G | Single-channel; 7.5 ns delay at 5 V; OVT to 7 V; same UDFN6 package (1.6 × 1.6 mm) | No triple integration - requires three devices for equivalent function; larger total footprint than single NLU3G14MUTAG | Choose when legacy design uses MC74VHC1GT14 and board space allows three separate placements; not a drop-in replacement |
Compared with SN74LVC1G14DBVR and MC74VHC1GT14DTT1G, the NLU3G14MUTAG delivers triple functionality in one 1.6 × 1.0 mm UDFN8 package with guaranteed OVT and hysteresis control - reducing PCB area by >60% and eliminating external protection components in multi-signal conditioning applications.

FAQ
What is the maximum input voltage the NLU3G14MUTAG can tolerate?
The NLU3G14MUTAG supports DC input voltages from −0.5 V to +7.0 V on all pins-regardless of VCC level. This overvoltage tolerance eliminates the need for external clamping diodes when interfacing with higher-voltage sources like 5 V sensor outputs or legacy bus signals, and is verified per the Absolute Maximum Ratings table in the official datasheet.
Does the NLU3G14MUTAG support operation at 1.8 V supply?
Yes, the NLU3G14MUTAG is fully specified for operation from 1.65 V to 5.5 V. At 1.8 V, it maintains functional Schmitt-trigger behavior with VT+ ≈ 1.15 V and VT− ≈ 0.65 V (interpolated from DC Electrical Characteristics), making it suitable for modern ultra-low-power microcontroller I/O domains.
How many independent Schmitt-trigger inverters does the NLU3G14MUTAG contain?
The NLU3G14MUTAG contains exactly three independent Schmitt-trigger inverters (A1→Y1, A2→Y2, A3→Y3), each with identical hysteresis, propagation delay, and overvoltage tolerance. Pin assignments and logic symbols in Figures 1 and 2 of the datasheet confirm full functional separation with no shared internal nodes.
What package type and dimensions does the NLU3G14MUTAG use?
The NLU3G14MUTAG is packaged in UDFN8 (case 517BY), measuring 1.6 mm × 1.0 mm with 0.4 mm pitch. Its footprint and soldering recommendations are detailed in Package Dimensions page 5 of the datasheet, including land pattern and stencil guidelines for reliable reflow assembly.
Is the NLU3G14MUTAG compliant with RoHS and Pb-free requirements?
Yes, the NLU3G14MUTAG is a Pb-free device meeting RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity Level 1. The "MUTAG" suffix explicitly denotes Pb-free packaging, and the device is qualified for standard lead-free reflow profiles without pre-baking.
