Product details
Overview
NLX3G14BMX1TCG from onsemi is a triple Schmitt-trigger inverter IC in an ultra-small UDFN8 (1.45 × 1.0 mm, 0.35 mm pitch) package, designed for 1.65 V to 5.5 V operation with overvoltage-tolerant I/O pins up to 7.0 V, balanced ±24 mA output drive, and propagation delays as low as 1.0 ns at 5 V - used to square slow-rising waveforms and enhance noise immunity in space-constrained digital interfaces.
For engineers reviewing the NLX3G14BMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.1–1.7 V), input threshold symmetry (VT+ = 0.6–3.6 V, VT− = 0.2–2.3 V), OVT capability, ultra-low ICC (≤10 µA), and UDFN8 thermal/mechanical compatibility with high-density PCB layouts.
Technical Context
The NLX3G14BMX1TCG implements three independent Schmitt-trigger inverters with symmetric positive/negative input thresholds and programmable hysteresis determined by supply voltage (VH = VT+ − VT−). Each inverter features overvoltage-tolerant inputs and outputs rated to ±7.0 V regardless of VCC, enabling safe interfacing between mixed-voltage domains.
Its CMOS architecture delivers balanced source/sink current (±24 mA), matched tPLH/tPHL propagation delays (1.0–9.1 ns depending on VCC and load), and low dynamic power consumption via CPD = 11–12.5 pF - optimized for signal conditioning in battery-powered and industrial control systems operating from −55°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. |
| Input Thresholds | VT+ = 0.6–3.6 V, VT− = 0.2–2.3 V - enables robust noise margin tuning per supply voltage. |
| Hysteresis Voltage | VH = 0.1–1.7 V - provides stable switching against slow edges and EMI without external components. |
| Propagation Delay | tPLH/tPHL = 1.0–9.1 ns - ensures timing predictability under RL = 500 Ω / CL = 50 pF and VCC = 4.5–5.5 V. |
| Output Drive | ±24 mA - sustains rail-to-rail logic transitions into moderate capacitive loads without external buffers. |
| Overvoltage Tolerance | Inputs/outputs withstand −0.5 V to +7.0 V - eliminates level-shifters when interfacing with higher-voltage sensors or legacy peripherals. |
| ICC (Quiescent) | ≤10 µA max at TA = 25°C - enables always-on signal conditioning in ultra-low-power wake-up circuits. |
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 overvoltage-tolerant digital signals up to 7.0 V. |
| 2 | IN A1 | Input of first Schmitt-trigger inverter; shares same electrical characteristics and OVT protection as Pin 1. |
| 3 | OUT Y3 | Output of third inverter; delivers rail-to-rail CMOS-compatible logic levels with ±24 mA drive strength. |
| 4 | OUT Y2 | Output of second inverter; electrically isolated from other outputs; supports independent loading. |
| 5 | GND | Dedicated ground reference for all three inverters; decoupling capacitor placement critical for noise immunity. |
| 6 | IN A3 | Input of third Schmitt-trigger inverter; identical threshold and hysteresis behavior to Pins 1 and 2. |
| 7 | OUT Y1 | Output of first inverter; matches propagation delay and drive capability of Pins 3 and 4. |
| 8 | VCC | Primary power supply input; must be bypassed locally with ≥0.1 µF ceramic capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent hysteresis-based inverters in one die - reduces board area vs. discrete solutions and eliminates inter-device skew. |

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-trigger function but uses standard SC70-8 package (2.0 × 1.25 mm); lower hysteresis (VH ≈ 0.3–0.9 V); max VCC = 5.5 V. | Larger footprint; less effective for extreme-noise environments due to narrower hysteresis window. | Choose when board space allows larger package and lower-cost assembly is prioritized over minimal size. |
| MC74VHC14DT | Hex Schmitt-trigger inverter in SOIC-14; higher ICC (≤20 µA); wider VCC range (2.0–5.5 V); no OVT - max VIN = VCC + 0.5 V. | Requires external clamping for >5.5 V inputs; unsuitable for mixed-voltage interface without level shifting. | Choose when needing six channels and SOIC handling is acceptable; avoid where overvoltage tolerance is required. |
Compared with SN74LVC3G14DCUR and MC74VHC14DT, the NLX3G14BMX1TCG uniquely combines UDFN8 miniaturization, 7.0 V overvoltage tolerance, and tunable hysteresis - making it optimal for space-constrained, multi-rail industrial and automotive signal conditioning where reliability under voltage transients is critical.

FAQ
What is the maximum input voltage the NLX3G14BMX1TCG can tolerate?
The NLX3G14BMX1TCG supports DC input voltages from −0.5 V to +7.0 V on all input and output pins, regardless of VCC level - verified per maximum ratings table in the official datasheet. This overvoltage tolerance applies to both IN A1/A2/A3 and OUT Y1/Y2/Y3 terminals, enabling safe interfacing with higher-voltage peripherals without external protection components. The NLX3G14BMX1TCG maintains this rating across its full operating temperature range.
Does the NLX3G14BMX1TCG require external pull-up or pull-down resistors?
No, the NLX3G14BMX1TCG does not require external pull-up or pull-down resistors for normal operation - its CMOS inputs have negligible leakage (IIN ≤ ±1.0 µA), and internal structure ensures defined logic states when driven. However, floating inputs must be avoided; unused inputs should be tied to VCC or GND to prevent increased ICC and potential oscillation. The NLX3G14BMX1TCG's overvoltage-tolerant design permits direct tie-off to any valid logic rail within its −0.5 V to +7.0 V range.
What is the typical hysteresis voltage (VH) of the NLX3G14BMX1TCG at 3.3 V supply?
At VCC = 3.3 V, the NLX3G14BMX1TCG exhibits a typical hysteresis voltage (VH) of 0.93 V, calculated as VT+ (typ) − VT− (typ) = 2.2 V − 1.27 V. This value is confirmed in the DC Electrical Characteristics table under "VH Hysteresis Voltage" for VCC = 3.0 V ± 0.3 V. The NLX3G14BMX1TCG's VH scales with supply voltage, providing predictable noise margin adjustment across its 1.65–5.5 V operating range.
Can the NLX3G14BMX1TCG operate at −55°C?
Yes, the NLX3G14BMX1TCG is fully specified to operate from −55°C to +125°C, as stated in the Recommended Operating Conditions table. All key parameters - including propagation delay, output drive, input thresholds, and quiescent current - are guaranteed across this extended industrial temperature range. The NLX3G14BMX1TCG's qualification per JESD22-A104 (temperature cycling) and JESD22-A106 (highly accelerated stress test) confirms reliability in harsh environments.
Is the NLX3G14BMX1TCG pin-compatible with other MiniGate triple inverters?
The NLX3G14BMX1TCG shares identical pinout (UDFN8, 1.45 × 1.0 mm, 0.35 mm pitch) and logic function with other NLX3G14 variants (e.g., NLX3G14DMUTCG, NLX3G14EMUTCG), differing only in package dimensions and marking. It is not pin-compatible with non-UDFN8 packages like SC70-8 or SOIC-14. The NLX3G14BMX1TCG's pin assignment - IN A2 (1), IN A1 (2), OUT Y3 (3), OUT Y2 (4), GND (5), IN A3 (6), OUT Y1 (7), VCC (8) - is fixed and documented in Figure 1 and the PIN ASSIGNMENT table.
