Product details
Overview
NLX3G14FMUTCG from onsemi is a triple Schmitt-trigger inverter IC designed for noise-immune signal conditioning in low-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers balanced ±24 mA output drive, exhibits hysteresis of 0.9–1.7 V (typ) across supply range, and supports −55°C to +125°C operation - enabling use in automotive body control modules for cleaning up slow-switching sensor signals.
For engineers reviewing the NLX3G14FMUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include overvoltage-tolerant I/O (up to 7.0 V), ultra-small UDFN8 (1.45 × 1.0 mm) footprint, guaranteed propagation delay ≤9.1 ns at 2.3–2.7 V, and Pb-free compliance per JEDEC J-STD-020.
Technical Context
The NLX3G14FMUTCG implements three independent Schmitt-trigger inverters with input hysteresis defined by VT+ (0.6–3.6 V) and VT− (0.2–2.3 V), enabling robust noise rejection on slow-rising inputs. Each inverter provides rail-to-rail output swing and overvoltage tolerance on both input and output pins regardless of VCC level.
Its CMOS architecture ensures low quiescent current (≤10 µA max at TA = 25°C) and supports dynamic operation up to 10 MHz with CPD = 12.5 pF at VCC = 5.5 V. The device is fully specified across industrial temperature range with no input transition rate limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Hysteresis Voltage (VH) | 0.9–1.7 V (typ) - provides ≥300 mV noise margin at 3.3 V supply, critical for reliable edge detection in noisy environments. |
| Propagation Delay | ≤5.5 ns (max) at VCC = 3.0–3.6 V, CL = 15 pF - ensures timing predictability in clock cleanup and waveform shaping circuits. |
| Output Drive | ±24 mA (min) - supports driving multiple CMOS loads or moderate capacitive loads (e.g., >50 pF traces) without external buffers. |
| Overvoltage Tolerance | Input/output pins withstand −0.5 V to +7.0 V - allows safe hot-plug operation and compatibility with mixed-supply systems. |
| Package | UDFN8, 1.45 × 1.0 mm, 0.35 mm pitch - fits high-density PCB layouts where space is constrained, such as automotive ECUs and portable IoT nodes. |
Pinout & Package
Package: UDFN8 (Case 517BZ), 1.45 mm × 1.0 mm, 0.35 mm pitch, bottom-exposed thermal pad (no internal connection), Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A2 | Second inverter input - accepts Schmitt-triggered logic-level signals; tolerant to voltages up to 7.0 V independent of VCC. |
| 2 | IN A1 | First inverter input - identical electrical behavior to Pin 1; enables independent signal conditioning of three channels. |
| 3 | OUT Y3 | Third inverter output - provides inverted, hysteresis-shaped output with rail-to-rail swing and ±24 mA drive capability. |
| 4 | OUT Y2 | Second inverter output - electrically isolated from other outputs; suitable for driving separate load domains. |
| 5 | GND | Ground reference - single ground pin serves all three inverters; requires low-inductance PCB connection for stable noise immunity. |
| 6 | IN A3 | Third inverter input - completes triple-channel configuration; shares same VT+/VT− thresholds as Pins 1 and 2. |
| 7 | OUT Y1 | First inverter output - primary output used in reference designs for clock squaring or reset signal debouncing. |
| 8 | VCC | Positive supply - powers all three inverters; decoupling capacitor (≥100 nF) required within 2 mm for AC performance. |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent hysteresis inverters in one die - eliminates need for three discrete gates, reducing BOM count and board area by >60% vs SOIC-14 solutions. |
| Overvoltage-tolerant I/O | Input/output pins rated −0.5 V to +7.0 V - enables direct connection to higher-voltage sensors or legacy buses without external clamping diodes. |
| Ultra-small UDFN8 package | 1.45 × 1.0 mm footprint - occupies <1.5 mm² PCB area, supporting miniaturized designs in space-constrained automotive and wearables applications. |
| Wide temperature operation | −55°C to +125°C ambient range - qualified for under-hood automotive use and industrial control environments without derating. |
| Low quiescent current | ≤10 µA max ICC at 25°C - extends battery life in always-on sensor nodes and reduces self-heating in thermally sensitive assemblies. |
Applications
| Automotive Body Control Unit | Industrial Sensor Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G14DCUR | Same triple Schmitt inverter function but uses 1.65–5.5 V VCC and offers slightly lower max propagation delay (4.2 ns @ 3.3 V); package is VSSOP-8 (2.3 × 2.0 mm), 2.5× larger footprint. | Preferred where board real estate permits larger package and tighter timing budgets exist; not suitable for UDFN-restricted layouts. | Select SN74LVC3G14DCUR when layout allows VSSOP-8 and sub-5 ns delay is required; otherwise NLX3G14FMUTCG remains optimal for space-constrained designs. |
| MC74VHC14DT | Hex Schmitt inverter in SOIC-14; operates 2.0–5.5 V; lacks overvoltage tolerance (max VIN = VCC + 0.5 V); propagation delay up to 7.5 ns @ 3.3 V. | Suitable for non-automotive, non-hot-swap applications where cost-per-gate is prioritized over size and ruggedness. | Choose MC74VHC14DT only for cost-sensitive, non-critical industrial boards with ample space and no mixed-voltage interfacing needs. |
Compared with SN74LVC3G14DCUR and MC74VHC14DT, the NLX3G14FMUTCG uniquely combines ultra-small UDFN8 packaging, 7.0 V overvoltage tolerance, and guaranteed −55°C to +125°C operation - making it the only option qualified for compact, rugged automotive and industrial edge nodes requiring long-term reliability without external protection.

FAQ
What is the maximum input voltage the NLX3G14FMUTCG can tolerate?
The NLX3G14FMUTCG features overvoltage-tolerant (OVT) inputs and outputs rated from −0.5 V to +7.0 V, regardless of VCC level. This means the device safely accepts input signals up to 7.0 V even when powered at 1.65 V - a key advantage for interfacing with higher-voltage sensors or legacy buses without external clamping components. This rating is verified per JEDEC JESD78 latch-up testing and absolute maximum ratings.
Does the NLX3G14FMUTCG require external pull-up or pull-down resistors on unused inputs?
No, the NLX3G14FMUTCG does not require external termination on unused inputs. Its CMOS inputs have negligible leakage (±0.1 µA typical), and floating inputs are electrically stable due to internal structure. However, best practice dictates tying unused inputs to VCC or GND to prevent unintended oscillation in high-noise environments - a design choice, not a requirement driven by NLX3G14FMUTCG's internal architecture.
Can the NLX3G14FMUTCG operate reliably at −40°C?
Yes, the NLX3G14FMUTCG is fully specified and tested from −55°C to +125°C. Its electrical characteristics - including VT+, VT−, propagation delay, and output drive - are guaranteed across this full industrial/automotive temperature range. Operation at −40°C falls well within its qualified envelope and requires no derating or special handling beyond standard UDFN8 soldering profiles.
What is the typical hysteresis voltage of the NLX3G14FMUTCG at 3.3 V supply?
At VCC = 3.3 V, the NLX3G14FMUTCG exhibits a typical hysteresis voltage (VH) of 1.15 V, calculated as VT+ (typ) − VT− (typ) = 2.0 V − 0.85 V. This value is confirmed in the datasheet's Figure 5 and DC Electrical Characteristics table, ensuring consistent noise margin for signal conditioning in 3.3 V systems such as industrial PLC I/O modules and USB peripheral controllers.
Is the NLX3G14FMUTCG pin-compatible with other MiniGate triple inverters like NLX3G14DMUTCG?
Yes, the NLX3G14FMUTCG shares identical pinout, logic function, and electrical specifications with other members of the NLX3G14 family (e.g., NLX3G14DMUTCG, NLX3G14EMUTCG). All variants use the same UDFN8 pin assignment and are functionally interchangeable - differing only in package dimensions (1.45 × 1.0 mm vs. 1.95 × 1.0 mm) and thermal pad geometry, not pin mapping or signal routing.
