Product details
Overview
NLU3G14AMX1TCG from onsemi is a triple Schmitt-trigger inverter IC 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 (7.0 V) inputs/outputs - enabling robust interfacing in mixed-voltage industrial sensor interfaces.
For engineers reviewing the NLU3G14AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.30–1.60 V), ultra-small UDFN8 package footprint (1.45 × 1.0 mm), input leakage ≤±1.0 µA, and guaranteed operation from −55°C to +125°C in automotive and industrial control environments.
Technical Context
The NLU3G14AMX1TCG implements three independent Schmitt-trigger inverter stages in a single ultra-thin UDFN8 package, each with asymmetric hysteresis (VT+ = 1.85–3.85 V, VT− = 0.9–3.05 V at VCC = 3.0–5.5 V). Its input structure tolerates voltages up to 7.0 V regardless of supply, enabling safe level-shifting between 3.3 V and 5 V domains without external clamping.
Propagation delay is tightly controlled (tPLH/tPHL = 4.0–17 ns depending on VCC and load), with balanced rise/fall characteristics and low dynamic power (CPD = 7.0 pF). The device includes power-down protection and meets Level 1 moisture sensitivity per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V logic families |
| Propagation Delay (Typ) | 4.0 ns @ VCC = 5.0 V, CL = 15 pF - enables high-speed waveform squaring in clock/data recovery paths |
| Hysteresis Voltage | 0.30–1.60 V - provides configurable noise margin against EMI in motor control feedback or sensor signal chains |
| Input Overvoltage Tolerance | −0.5 V to +7.0 V - eliminates need for external series resistors when interfacing with higher-voltage analog sensors |
| Output Drive Capability | ±12.5 mA - sufficient to directly drive LED indicators or small capacitive loads (<50 pF) without buffering |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive and industrial PLC applications |
| Input Leakage Current | ±1.0 µA max - preserves signal integrity in high-impedance sensor node inputs |
Pinout & Package
Package: UDFN8 (1.45 mm × 1.0 mm, 0.35 mm pitch), Pb-free, moisture sensitivity Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A2 | Inverter stage 2 input - accepts slow-rising signals (e.g., thermistor RC outputs) and squares them with hysteresis |
| 2 | IN A1 | Inverter stage 1 input - primary signal conditioning path with identical Schmitt thresholds to pins 1 and 6 |
| 3 | OUT Y3 | Inverter stage 3 output - provides clean CMOS-level output after noise rejection and edge sharpening |
| 4 | OUT Y2 | Inverter stage 2 output - electrically isolated from other outputs; drives local logic or status indicator |
| 5 | GND | Ground reference - must be connected to system ground plane; shared return for all three inverters |
| 6 | IN A3 | Inverter stage 3 input - independent input for third signal path (e.g., watchdog timeout detection) |
| 7 | OUT Y1 | Inverter stage 1 output - first-stage output used for clock cleanup or reset signal generation |
| 8 | VCC | Positive supply - powers all three inverters; decoupling capacitor (0.1 µF) required within 2 mm |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent hysteresis inverters in one die - reduces board area vs. discrete solutions and ensures matched timing |

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; 3.3 V optimized; no 7.0 V overvoltage tolerance | Requires external clamping for >3.6 V inputs; unsuitable for mixed-voltage sensor front-ends | Select when only one inverter needed and system operates strictly at 3.3 V with clean supply |
| MC74VHC1GT14DTT1G | Single-channel; 2.0–5.5 V range; 5.5 V absolute max rating (not 7.0 V tolerant) | Lacks overvoltage protection - vulnerable to transient coupling in noisy industrial environments | Choose for cost-sensitive consumer applications where input transients are controlled and layout is short |
Compared with SN74LVC1G14DBVR and MC74VHC1GT14DTT1G, the NLU3G14AMX1TCG uniquely delivers triple functionality, 7.0 V I/O tolerance, and sub-2 mm² footprint - making it the only option for space-constrained, mixed-voltage, high-noise industrial signal conditioning.

FAQ
What is the maximum input voltage the NLU3G14AMX1TCG can tolerate?
The NLU3G14AMX1TCG supports DC input voltages from −0.5 V to +7.0 V regardless of supply voltage - a key feature enabling direct connection to higher-voltage sensors or legacy 5 V logic without level shifters. This overvoltage tolerance is verified per JEDEC JESD78 latch-up testing and applies to both input and output pins.
Does the NLU3G14AMX1TCG require external pull-up or pull-down resistors on its inputs?
No, the NLU3G14AMX1TCG does not require external biasing resistors. Its CMOS inputs have low leakage (≤±1.0 µA) and defined switching thresholds (VT+ and VT−), allowing direct connection to open-drain or floating sources. However, unused inputs should be tied to VCC or GND to prevent floating states and unintended current draw.
What is the hysteresis voltage range of the NLU3G14AMX1TCG across operating conditions?
The NLU3G14AMX1TCG provides hysteresis voltage (VH) ranging from 0.30 V (min at VCC = 3.0 V, TA = 25°C) to 1.60 V (max at VCC = 5.5 V, TA = −55°C to +125°C). This wide, temperature-stable hysteresis ensures consistent noise margin in automotive under-hood and industrial factory-floor environments.
Can the NLU3G14AMX1TCG operate reliably at 1.65 V supply?
Yes, the NLU3G14AMX1TCG is fully specified down to 1.65 V supply voltage per its Recommended Operating Conditions table. At this minimum VCC, propagation delay increases (e.g., tPLH/tPHL ≤ 17 ns at CL = 15 pF), but logic thresholds and hysteresis remain functional - enabling use in ultra-low-power battery systems.
Is the NLU3G14AMX1TCG pin-compatible with other UDFN8 triple inverters?
No documented pin-compatible alternatives exist for the NLU3G14AMX1TCG. Its pin assignment (IN A2, IN A1, OUT Y3, OUT Y2, GND, IN A3, OUT Y1, VCC) is unique to the MiniGate family. Substituting other UDFN8 inverters requires PCB redesign due to differing pinouts and internal signal routing.
