Product details
Overview
NLU3G16DMUTCG from onsemi is a triple non-inverting buffer IC in ultra-small UDFN8 (1.95 × 1.0 mm) package, designed for high-speed signal buffering in space-constrained digital systems. It operates from 1.65 V to 5.5 V, delivers 3.5 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 - enabling robust interfacing in mixed-voltage or hot-swap applications.
For engineers reviewing the NLU3G16DMUTCG datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, validated pin functions, real-world use cases in level-shifting and bus buffering, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The NLU3G16DMUTCG implements three independent CMOS non-inverting buffer stages in a single die, each with symmetrical input/output structures enabling bidirectional voltage translation capability. Its overvoltage-tolerant inputs and outputs allow safe operation when VIN or VOUT exceeds VCC by up to 2.0 V - critical for I²C pull-up domains, GPIO expansion, and legacy interface bridging.
Propagation delays are balanced across all three channels (tPLH ≈ tPHL), and power-down protection prevents back-driving during VCC = 0 V conditions. The device meets JEDEC JESD78 latch-up immunity (±500 mA) and is rated for operation from −55°C to +125°C, supporting industrial and automotive under-hood environments.
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 level shifters |
| tPD (Typ) | 3.5 ns @ VCC = 5.0 V, CL = 15 pF - supports >100 MHz data rates in short-trace buffered paths |
| IO Max | ±12.5 mA per output - sufficient to drive standard CMOS loads and moderate PCB trace capacitance |
| VIN/VOUT Rating | −0.5 V to +7.0 V - allows safe connection to higher-voltage buses (e.g., 5 V I²C) while powered from 1.8 V |
| ICC (Max) | 10 µA @ TA = 25°C - ensures negligible static current draw in always-on monitoring circuits |
| Operating Temp | −55°C to +125°C - qualified for extended-temperature industrial control and automotive body electronics |
| Moisture Sensitivity | MSL Level 1 - no bake required before reflow; compatible with standard SMT assembly processes |
Pinout & Package
Package: UDFN8 (1.95 mm × 1.0 mm, 0.5 mm pitch), Pb-free, bottom-terminal surface-mount. Exposed pad optional (not electrically connected per datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A1 | Input for first buffer channel; OVT structure accepts up to 7.0 V regardless of VCC |
| 2 | OUT Y3 | Output for third buffer channel; drives CMOS loads with ±12.5 mA capability |
| 3 | IN A2 | Input for second buffer channel; electrically isolated from other inputs |
| 4 | GND | Dedicated ground reference for all three buffers; decoupling capacitor must be placed adjacent |
| 5 | OUT Y2 | Output for second buffer channel; matched propagation delay to Y1/Y3 for timing-critical routing |
| 6 | IN A3 | Input for third buffer channel; supports same overvoltage tolerance and input leakage (<±0.1 µA) |
| 7 | OUT Y1 | Output for first buffer channel; pin 7 placement enables compact fanout to adjacent ICs |
| 8 | VCC | Single positive supply for all three buffers; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-Tolerant I/O | Inputs and outputs withstand −0.5 V to +7.0 V independent of VCC - eliminates external clamping diodes in mixed-rail systems |
| Balanced Propagation Delay | tPLH and tPHL match within 0.5 ns across all channels - preserves signal integrity in parallel data paths |
| Power-Down Protection | Inputs remain high-impedance and non-latching when VCC = 0 V - prevents back-powering of supply rails |
| Ultra-Small Footprint | UDFN8 1.95 × 1.0 mm saves >60% board area vs. SOIC-8 - ideal for wearables and sensor nodes |
| Pb-Free & RoHS Compliant | Meets IPC/JEDEC J-STD-020 moisture sensitivity Level 1 - supports lead-free reflow without preconditioning |

IC Role / Device Role / Timing Role: Fault-tolerant buffer protecting MCU inputs from load-dump transients and ESD events on actuator harnesses. Use Value: Withstands 7.0 V transient spikes on IN pins while VCC = 3.3 V - avoids need for TVS diodes on every interrupt line, reducing layout complexity. |
Use Scenario: Driving LED indicators and buzzer enable signals from a low-power 1.8 V ARM Cortex-M0+ in a battery-operated glucose meter. IC Role / Device Role / Timing Role: Low-quiescent-current buffer amplifying weak MCU outputs to drive 5 mA indicator loads without voltage droop.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G17DCUR | Same 3-channel non-inverting function but rated only to 5.5 V I/O (no 7.0 V OVT); slightly higher ICC (20 µA max) | Lacks overvoltage tolerance - unsuitable for mixed-voltage hot-swap interfaces where inputs may float above VCC | Select when operating exclusively within 1.65–5.5 V rail constraints and cost is prioritized over fault margin |
| NC7SZ17P5X | SC-70-5 package (single channel); requires three devices for equivalent functionality; 5.0 V max I/O rating | No OVT support and smaller output drive (±8 mA); not pin-compatible - requires PCB redesign | Choose only for prototyping or low-volume designs where board space is less constrained than cost |
Compared with SN74LVC3G17DCUR and NC7SZ17P5X, the NLU3G16DMUTCG uniquely combines triple-channel integration, 7.0 V overvoltage tolerance, and sub-2 mm² footprint - making it the only option that eliminates discrete protection components while maintaining minimal layout area in mixed-rail embedded systems.

FAQ
What is the maximum input voltage the NLU3G16DMUTCG can tolerate when VCC = 1.8 V?
The NLU3G16DMUTCG supports DC input voltages from −0.5 V to +7.0 V on all IN pins, regardless of VCC level. When powered from 1.8 V, it safely accepts 5 V or even 7 V signals without damage or latch-up - a key advantage over standard logic buffers. This overvoltage tolerance is confirmed in the Maximum Ratings table of the official datasheet.
Does the NLU3G16DMUTCG require external pull-up resistors on its inputs?
No, the NLU3G16DMUTCG does not require external pull-up resistors on its inputs. Its CMOS inputs have negligible leakage current (±0.1 µA max), and internal structure ensures defined logic states when driven. Pull-ups are only needed if the driving source is open-drain or if a default-high state is required during power-up - not due to NLU3G16DMUTCG input characteristics.
Can the NLU3G16DMUTCG be used as a level shifter between 1.8 V and 5 V domains?
Yes, the NLU3G16DMUTCG functions as a unidirectional level shifter: a 1.8 V MCU can drive its inputs, and its outputs swing rail-to-rail up to VCC (e.g., 5 V). For bidirectional translation (e.g., I²C), its OVT inputs/outputs allow passive pull-up to higher voltage - confirmed in application notes AN-111 and AND8410/D. No additional components are needed beyond pull-up resistors on the high-voltage side.
What is the thermal resistance (θJA) of the NLU3G16DMUTCG in its UDFN8 package?
The datasheet does not specify θJA for the NLU3G16DMUTCG UDFN8 (1.95 × 1.0 mm) variant. However, based on onsemi's published thermal data for identical-case UDFN8 packages (e.g., NLU3G04), θJA is approximately 220°C/W on a 1-inch², 2-oz copper FR4 board with minimum pad spacing. For precise thermal design, users should validate with actual board layout and airflow conditions.
Is the NLU3G16DMUTCG pin-compatible with other variants in the NLU3G16 family?
Yes, all NLU3G16 variants - including NLU3G16MUTAG, NLU3G16AMX1TCG, and NLU3G16DMUTCG - share identical 8-pin UDFN/ULLGA pinouts and logic functionality. The "D" in NLU3G16DMUTCG denotes the 1.95 × 1.0 mm UDFN8 package (Case 517CA), differing only in physical dimensions and thermal profile - not pin assignment or electrical behavior.
