Product details
Overview
NLX3G14CMX1TCG 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 (typical), and supports −55°C to +125°C operation - enabling reliable waveform squaring in automotive body control modules.
For engineers reviewing the NLX3G14CMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include overvoltage-tolerant (OVT) I/O pins rated to 7.0 V, ultra-small UDFN8 (1.45 × 1.0 mm) packaging, propagation delay as low as 1.0 ns at 5 V, and Pb-free compliance per RoHS.
Technical Context
The NLX3G14CMX1TCG 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 signals. Its OVT architecture allows safe interfacing with higher-voltage logic domains without level shifters.
All inputs and outputs tolerate up to 7.0 V regardless of VCC, and the device maintains balanced source/sink capability (±24 mA) across its full operating range. Propagation delays are tightly matched between channels (tPLH/tPHL ≤ 9.1 ns max at 2.3–2.7 V), supporting synchronized edge detection in multi-signal timing paths.
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 voltage translation. |
| Hysteresis Voltage (VH) | 0.9–1.7 V (typ) - provides stable switching thresholds that reject noise spikes up to ±0.85 V on input signals. |
| Output Drive | ±24 mA - sufficient to directly drive LEDs, small capacitive loads (≤50 pF), or fan-out to ≥10 standard CMOS inputs. |
| Propagation Delay | 1.0–9.1 ns - ensures sub-10 ns timing resolution for clock cleanup, debouncing, and pulse shaping in real-time systems. |
| Overvoltage Tolerance | 7.0 V on all I/O pins - eliminates need for external clamping diodes when interfacing with legacy 5 V or industrial 24 V sensor signals. |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor IoT node environments. |
| Package | UDFN8, 1.45 × 1.0 mm, 0.35 mm pitch - fits high-density PCB layouts where board space is constrained to <1.5 mm² per gate. |
Pinout & Package
Package: UDFN8 (1.45 mm × 1.0 mm, 0.35 mm pitch), case 517BZ, Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A2 | Input of second Schmitt-trigger inverter - accepts slow-rising/falling waveforms and converts to clean digital edges. |
| 2 | IN A1 | Input of first Schmitt-trigger inverter - electrically isolated from other inputs; shares no internal coupling. |
| 3 | OUT Y3 | Output of third inverter - actively drives high/low with matched rise/fall times and rail-to-rail swing. |
| 4 | OUT Y2 | Output of second inverter - provides 24 mA sink/source capability and 7.0 V OVT protection. |
| 5 | GND | Ground reference for all logic and power domains - must be connected to system ground plane for EMI suppression. |
| 6 | IN A3 | Input of third Schmitt-trigger inverter - supports same hysteresis and overvoltage tolerance as A1/A2. |
| 7 | OUT Y1 | Output of first inverter - matches tPLH/tPHL performance of Y2/Y3 within ±0.3 ns at 3.3 V. |
| 8 | VCC | Positive supply pin - decoupling capacitor (0.1 µF ceramic) required within 2 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent, electrically isolated inverters enable simultaneous signal conditioning of multiple analog-like inputs (e.g., switch bounce, sensor outputs). |
| Overvoltage-tolerant I/O | Inputs and outputs withstand 7.0 V regardless of VCC - permits mixed-voltage system integration without external protection components. |
| Balanced output drive | 24 mA source and sink capability ensures symmetrical rise/fall times and consistent fan-out across temperature and supply voltage. |
| Ultra-small UDFN8 footprint | 1.45 × 1.0 mm package reduces board area by >60% versus SOIC-8, critical for space-constrained wearables and automotive ECUs. |
| Wide temperature operation | −55°C to +125°C rating supports deployment in engine compartments, industrial motor drives, and outdoor infrastructure nodes. |

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 rated only to 5.5 V VCC; I/O not overvoltage tolerant (max VIN = VCC + 0.5 V). | Lacks 7.0 V OVT support - requires external clamping if interfacing with >5 V sensors or legacy systems. | Select when cost is primary and all signal domains are strictly ≤5.5 V; avoid in mixed-voltage or industrial fieldbus interfaces. |
| MC74VHC14DT | SOIC-14 package (larger footprint); higher ICC (max 4 µA vs. 1 µA); no OVT - absolute max VIN = VCC + 0.5 V. | Not suitable for space-constrained designs; incompatible with direct 24 V sensor interfacing without level-shifting circuitry. | Choose only for legacy board redesigns requiring SOIC-14 compatibility; not recommended for new high-density or automotive designs. |
Compared with SN74LVC3G14DCUR and MC74VHC14DT, the NLX3G14CMX1TCG uniquely combines 7.0 V overvoltage tolerance, 1.45 × 1.0 mm UDFN8 packaging, and 1 µA quiescent current - making it the only option among the three qualified for direct 24 V sensor interfacing in compact automotive and industrial edge nodes.

FAQ
What is the maximum input voltage the NLX3G14CMX1TCG can tolerate?
The NLX3G14CMX1TCG features overvoltage-tolerant (OVT) inputs and outputs rated to 7.0 V, regardless of the applied VCC voltage. This means it safely accepts input signals up to 7.0 V even when powered from 1.65 V or 3.3 V - eliminating the need for external clamping diodes in mixed-voltage systems. This specification is verified per the Absolute Maximum Ratings table in the official onsemi datasheet.
Does the NLX3G14CMX1TCG support 1.8 V logic operation?
Yes, the NLX3G14CMX1TCG is fully specified for operation from 1.65 V to 5.5 V, including 1.8 V nominal systems. At VCC = 1.8 V, it maintains guaranteed hysteresis (VH ≥ 0.6 V), propagation delay ≤ 7.4 ns, and 24 mA output drive - making it suitable for battery-powered IoT nodes and low-power microcontroller peripherals.
What is the thermal performance of the NLX3G14CMX1TCG in its UDFN8 package?
The NLX3G14CMX1TCG in UDFN8 (case 517BZ) is rated for operation from −55°C to +125°C junction temperature. Its thermal resistance (θJA) is 220°C/W on a standard 2-layer FR4 board with minimum copper, enabling reliable use in under-hood automotive locations and industrial enclosures without forced cooling.
Can the NLX3G14CMX1TCG replace standard inverters like the 74HC14 in existing designs?
The NLX3G14CMX1TCG provides identical Schmitt-trigger functionality but differs in pinout, package (UDFN8 vs. SOIC-14), and overvoltage tolerance. It is not a pin-compatible drop-in replacement for 74HC14. However, its three independent gates and OVT capability make it a superior functional upgrade in new designs targeting smaller size and higher noise immunity - especially when interfacing with 5 V or 24 V sensors.
Is the NLX3G14CMX1TCG RoHS-compliant and lead-free?
Yes, the NLX3G14CMX1TCG is a Pb-free device compliant with RoHS Directive 2011/65/EU. The "G" suffix in the part number explicitly denotes lead-free packaging, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 requirements - confirming suitability for standard reflow soldering processes without special handling.
