Product details
Overview
NLX3G14AMX1TCG 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 V (typ) at 3.3 V, and supports −55°C to +125°C operation - used to square slow-rising waveforms in sensor interface and clock clean-up circuits.
For engineers reviewing the NLX3G14AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include overvoltage-tolerant (7.0 V) I/O pins, UDFN8-8 (1.45 × 1.0 mm) ultra-small footprint, propagation delay ≤5.5 ns at 5 V, and guaranteed latch-up immunity (±500 mA) at 125°C.
Technical Context
The NLX3G14AMX1TCG implements three independent Schmitt-trigger inverters with input hysteresis (VT+ = 1.9 V, VT− = 1.1 V typ at 3.3 V), enabling robust noise rejection on slow or noisy inputs. Its CMOS design ensures rail-to-rail output swing and symmetric VOH/VOL performance across supply voltages.
All inputs and outputs are overvoltage tolerant up to 7.0 V regardless of VCC, and the device features ESD protection >2 kV HBM. It is specified for full industrial temperature range (−55°C to +125°C) with quiescent ICC ≤10 µA max and no input transition rate limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Hysteresis Voltage (VH) | 0.9 V (typ) at 3.3 V - provides ≥300 mV noise margin for reliable switching in electrically noisy environments. |
| Propagation Delay | ≤5.5 ns (max) at VCC = 4.5–5.5 V, CL = 15 pF - supports clean signal regeneration up to ~100 MHz edge rates. |
| Output Drive | ±24 mA (source/sink) - sufficient to directly drive LEDs, small capacitive loads, or fan-out to multiple CMOS inputs. |
| Input/Output OVT | Rated to ±7.0 V - allows safe connection to higher-voltage signals (e.g., 5 V sensors on 1.8 V MCU systems) without external clamping. |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive, industrial control, and extended-range embedded applications. |
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 |
|---|---|---|

| 4 | OUT Y2 | Inverted output of second channel; electrically identical to Y1/Y3, fully decoupled per channel. |
| 5 | GND | Ground reference for all channels and internal circuitry; single ground pin serves entire triple gate. |
| 6 | IN A3 | Inverting input of third Schmitt-trigger channel; independently buffered with same input leakage (<±0.1 µA). |
| 7 | OUT Y1 | Inverted output of first channel; matches Y2/Y3 in VOH/VOL, tPLH/tPHL, and load drive capability. |
| 8 | VCC | Positive supply for all three inverters; powers internal biasing and output stages; tolerant to 7.0 V max. |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent, isolated inverter channels with matched VT+, VT−, and VH - eliminates crosstalk and enables parallel signal conditioning paths. |
| Overvoltage-tolerant I/O | Inputs and outputs withstand up to 7.0 V regardless of VCC - enables mixed-voltage system interfacing without external protection diodes. |
| Ultra-small UDFN8 package | 1.45 mm × 1.0 mm footprint with 0.35 mm pitch - saves >60% board area vs. standard SOIC-8 while maintaining thermal performance. |
| Wide temperature qualification | Guaranteed operation from −55°C to +125°C - validated for automotive engine control units, industrial PLCs, and outdoor IoT nodes. |
| No input transition rate limit | Functional across all input slew rates (0 ns/V to unlimited) - reliably squares arbitrarily slow analog-like edges (e.g., thermistor or potentiometer outputs). |

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 6.5 V I/O tolerance; 1.65–5.5 V VCC; slightly higher ICC (20 µA max). | Valid for commercial/industrial use but not qualified for extended temp (−55°C); lacks latch-up rating at 125°C. | Choose when cost is primary and extended temperature or 7.0 V OVT is not required. |
| MC74VHC14DT | SOIC-14 package; 2.0–5.5 V VCC; 6-channel; lower drive (±8 mA); no 7.0 V OVT - requires external clamping above VCC. | Requires more board space and external protection for mixed-voltage interfaces; unsuitable for ultra-compact designs. | Choose only if legacy SOIC footprint or higher channel count outweighs size and protection advantages of NLX3G14AMX1TCG. |
Compared with SN74LVC3G14DCUR and MC74VHC14DT, the NLX3G14AMX1TCG uniquely combines 7.0 V overvoltage tolerance, −55°C to +125°C qualification, and 1.45 mm × 1.0 mm UDFN8 packaging - making it optimal for space-constrained, high-reliability industrial and automotive signal conditioning where voltage transients and temperature extremes coexist.

FAQ
What is the maximum input voltage the NLX3G14AMX1TCG can tolerate?
The NLX3G14AMX1TCG 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 - eliminating need for external clamping diodes in mixed-voltage interfaces. The NLX3G14AMX1TCG maintains this rating across its full operating temperature range.
Does the NLX3G14AMX1TCG support operation at −55°C?
Yes, the NLX3G14AMX1TCG is fully specified and tested for operation from −55°C to +125°C. Its DC and AC electrical characteristics - including propagation delay, hysteresis voltage, and output drive - are guaranteed across this extended industrial temperature range. This makes the NLX3G14AMX1TCG suitable for under-hood automotive, outdoor infrastructure, and military-grade embedded systems.
What is the typical hysteresis voltage of the NLX3G14AMX1TCG at 3.3 V supply?
At VCC = 3.3 V, the NLX3G14AMX1TCG exhibits a typical hysteresis voltage (VH) of 0.9 V, calculated as VT+ (typ 1.9 V) minus VT− (typ 1.0 V). This provides a robust noise margin for reliable switching in electrically noisy environments such as motor drives or industrial sensor nodes. The NLX3G14AMX1TCG maintains consistent hysteresis behavior across its full supply and temperature range.
Can the NLX3G14AMX1TCG drive a 50 pF load with sub-7 ns propagation delay?
Yes - at VCC = 4.5–5.5 V and CL = 50 pF, the NLX3G14AMX1TCG achieves a maximum propagation delay of 6.4 ns (tPLH/tPHL). This performance is guaranteed under recommended operating conditions and enables clean signal regeneration for clock distribution, encoder feedback, and other time-critical digital conditioning tasks. The NLX3G14AMX1TCG sustains this speed without compromising output drive or noise immunity.
Is the NLX3G14AMX1TCG pin-compatible with other triple Schmitt-trigger inverters in UDFN8 packages?
The NLX3G14AMX1TCG uses a standardized UDFN8 pinout (1.45 × 1.0 mm, 0.35 mm pitch) matching the JEDEC MO-229WEED outline. However, pin compatibility with other triple Schmitt-trigger devices (e.g., SN74LVC3G14DCUR) is not guaranteed due to differences in internal pin mapping - always verify pin assignments against each device's datasheet before substitution. The NLX3G14AMX1TCG's pinout is explicitly defined in Figure 1 and PIN ASSIGNMENT table of its official datasheet.
