Product details
Overview
NLU3G17CMX1TCG from onsemi is a triple non-inverting Schmitt-trigger buffer in an ultra-small UDFN8 (1.45 × 1.0 mm) package, 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 (OVT) I/O pins rated to 7.0 V independent of supply voltage.
For engineers reviewing the NLU3G17CMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.30–1.60 V), input threshold symmetry (VT+ = 1.85–3.85 V, VT− = 0.9–3.05 V), OVT robustness, UDFN8 thermal and layout constraints, and quiescent current ≤10 µA.
Technical Context
The NLU3G17CMX1TCG implements three independent Schmitt-trigger input stages with balanced tPLH/tPHL propagation delays and rail-to-rail output swing. Its input structure provides power-down protection and latch-up immunity per JESD78 (±500 mA), enabling hot-swap compatibility and safe operation during partial power-down.
Each channel exhibits programmable noise margin via hysteresis (VH = 0.30–1.60 V depending on VCC and temperature), with guaranteed VT+ and VT− thresholds across −55°C to +125°C. The device uses advanced CMOS process technology optimized for low ICC (≤10 µA) while maintaining high-speed performance (tPD ≤11.5 ns max at 5.5 V, CL = 50 pF).
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 domains |
| tPD (Typ) | 4.0 ns @ VCC = 5.0 V, CL = 15 pF - enables timing-critical signal reshaping in high-frequency digital interfaces |
| VT+ / VT− | 1.85–3.85 V / 0.9–3.05 V - defines precise switching thresholds for reliable noise rejection in slow-edge environments |
| VH (Hysteresis) | 0.30–1.60 V - sets minimum input noise margin required to prevent false triggering |
| OVT Rating | ±7.0 V on all I/O pins - allows interfacing with higher-voltage signals without level shifters or clamping diodes |
| ICC (Max) | 10 µA @ TA = 25°C - ensures ultra-low static power in battery-powered or always-on monitoring circuits |
| IO (Max) | ±12.5 mA - drives standard CMOS loads and short PCB traces without external buffering |
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 to second Schmitt-trigger buffer; accepts overvoltage-tolerant digital signals up to 7.0 V |
| 2 | IN A1 | Input to first Schmitt-trigger buffer; shares same OVT and threshold characteristics as Pin 1 |
| 3 | OUT Y3 | Output of third buffer; rail-to-rail CMOS swing referenced to VCC and GND |
| 4 | OUT Y2 | Output of second buffer; electrically isolated from other outputs; supports independent load driving |
| 5 | GND | Dedicated ground reference for all three channels; must be low-impedance for stable hysteresis behavior |
| 6 | IN A3 | Input to third Schmitt-trigger buffer; identical electrical specs to Pins 1 and 2 |
| 7 | OUT Y1 | Output of first buffer; matches propagation delay and drive strength of other outputs |
| 8 | VCC | Positive supply for all three buffers; decoupling capacitor (≥100 nF) required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent, matched-input threshold channels enable simultaneous noise filtering of multiple slow-rising signals |
| Overvoltage-tolerant I/O | All pins withstand −0.5 V to +7.0 V regardless of VCC state - eliminates need for external protection in mixed-voltage systems |
| Balanced propagation delays | tPLH and tPHL match within ±1.5 ns across temperature - preserves signal timing integrity in parallel data paths |
| Ultra-small UDFN8 footprint | 1.45 × 1.0 mm outline saves >65% board area vs. SOIC-8 - ideal for wearables, IoT sensors, and compact MCU peripherals |
| Power-down input protection | Inputs remain high-impedance and non-latching when VCC = 0 V - prevents back-powering or bus contention during power sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Single-channel, SOT-23-5 package (2.9 × 1.6 mm); lower hysteresis (≈0.2 V typ); no OVT - requires VCC-referenced input limits | Not suitable for mixed-voltage or transient-prone interfaces; limited to 1.65–5.5 V clean-rail environments | Choose when only one buffer is needed and board space permits larger footprint; verify input voltage compliance strictly |
| MC74VHC1GT50DTT1G | Single non-inverting buffer (no Schmitt trigger); 3.5 ns tPD @ 5 V; no hysteresis; OVT not specified - max VIN = VCC + 0.5 V | Cannot suppress noise or square slow edges; unsuitable for debouncing or sensor digitization | Select only for pure signal buffering where waveform shape and noise immunity are irrelevant |
Compared with SN74LVC1G17DBVR and MC74VHC1GT50DTT1G, the NLU3G17CMX1TCG uniquely combines triple-channel integration, guaranteed hysteresis, and true 7.0 V OVT in a 1.45 mm × 1.0 mm package - making it the only option for space-constrained, multi-signal, mixed-voltage noise conditioning.

FAQ
What is the maximum input voltage the NLU3G17CMX1TCG can tolerate without damage?
The NLU3G17CMX1TCG supports DC input voltages from −0.5 V to +7.0 V on all pins - including IN A1, A2, A3, OUT Y1, Y2, Y3, VCC, and GND - regardless of supply voltage. This overvoltage tolerance is verified per maximum ratings and enables direct connection to higher-voltage sources without external protection components.
Does the NLU3G17CMX1TCG require external pull-up or pull-down resistors on its inputs?
No, the NLU3G17CMX1TCG does not require external biasing resistors. Its Schmitt-trigger inputs have defined VT+ and VT− thresholds and exhibit high-impedance behavior with leakage current ≤±1.0 µA. Pull resistors would degrade noise margin and are unnecessary unless specific system-level bus termination is required.
Can the NLU3G17CMX1TCG operate reliably at 1.65 V supply voltage?
Yes, the NLU3G17CMX1TCG is fully specified down to VCC = 1.65 V, with guaranteed VT+ ≥1.85 V and VT− ≤0.9 V at 25°C. Propagation delay increases to ≤17 ns (CL = 15 pF), and hysteresis remains functional - making it suitable for ultra-low-voltage battery-powered designs.
What is the thermal resistance (θJA) of the NLU3G17CMX1TCG in its UDFN8 package?
The NLU3G17CMX1TCG in UDFN8 (case 517BZ) has a typical junction-to-ambient thermal resistance (θJA) of 220°C/W when mounted on a standard 1-inch × 1-inch FR-4 board with 2-ounce copper and minimum pad spacing. No heatsink or thermal vias are required for normal operation below 10 mW total dissipation.
Is the NLU3G17CMX1TCG pin-compatible with other variants in the NLU3G17 family?
Yes, all NLU3G17 variants - including NLU3G17MUTAG, NLU3G17DMUTCG, NLU3G17EMUTCG, and NLU3G17FMUTCG - share identical UDFN8 pinout and electrical functionality. The NLU3G17CMX1TCG corresponds to the 1.45 × 1.0 mm variant (case 517BZ) and may be substituted without PCB changes if pad layout matches the 0.35 mm pitch footprint.
