Product details
Overview
NL17SG34AMUTCG from onsemi is a single high-speed CMOS buffer IC in ultra-small UDFN6 (1.45 mm × 1.0 mm) package, operating from 0.9 V to 3.6 V supply, delivering 2.3 ns typical propagation delay at 3.0 V/15 pF, with 4.6 V overvoltage-tolerant inputs and ±20 mA output drive-used for level-shifting and signal conditioning in space-constrained portable logic interfaces.
For engineers reviewing the NL17SG34AMUTCG datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, validated UDFN6 pin mapping, real-world use cases in battery-powered logic interfacing, and two confirmed alternative buffers with documented functional and packaging differences.
Technical Context
The NL17SG34AMUTCG implements a non-inverting digital buffer with rail-to-rail input tolerance up to 4.6 V independent of VCC, enabling mixed-voltage domain interfacing (e.g., 1.8 V logic driving 3.3 V systems). Its CMOS output stage supports ±20 mA sink/source capability across −55°C to +125°C.
Propagation delay varies predictably with VCC and load: 3.9 ns max at 2.3–2.7 V/30 pF, tightening to 3.1 ns max at 3.0–3.6 V/15 pF. Input leakage remains ≤1.0 µA across 0–3.6 V input range, supporting low-power always-on monitoring paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without level shifters |
| tPD (Typ) | 2.3 ns at VCC = 3.0 V, CL = 15 pF - supports >200 MHz signal integrity in short-trace board routing |
| Input Voltage Tolerance | −0.5 V to +4.6 V - allows safe connection to higher-voltage signals (e.g., 3.3 V or 4.2 V battery rails) without external clamping |
| IOUT (Max) | ±20 mA - drives multiple 74LVC inputs or small capacitive loads (<30 pF) without buffering |
| ICC (Max) | 10.0 µA at VCC = 3.6 V - supports ultra-low-quiescent-current sleep modes in IoT sensor nodes |
| Operating Temp | −55°C to +125°C - qualified for under-hood automotive, industrial control, and extended-temperature embedded applications |
| CIN | 3 pF - minimizes capacitive loading on upstream drivers, preserving edge rate in fanout-1 configurations |
Pinout & Package
Package: UDFN6 (1.45 mm × 1.0 mm, 0.5 mm pitch), wettable flank, Pb-free, halide-free - optimized for automated optical inspection (AOI) and high-density PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function |
| 2 | IN A | Digital input node tolerant to −0.5 V to +4.6 V - accepts logic-high thresholds as low as 0.65×VCC |
| 3 | GND | Primary ground reference for both input and output stages - requires low-inductance local decoupling |
| 4 | NC | No Connect (NC); electrically isolated - no internal connection, may be used for thermal pad anchoring |
| 5 | OUT Y | CMOS push-pull output with rail-to-rail swing - sources/sinks ±20 mA while maintaining VOH ≥ VCC−0.45 V / VOL ≤ 0.4 V |
| 6 | VCC | Single positive supply input - powers both input protection circuitry and output driver; bypass capacitor required within 2 mm |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-Tolerant Inputs | 4.6 V absolute max input voltage - eliminates need for external series resistors or clamp diodes when interfacing legacy 3.3 V or battery-sensed signals |
| Ultra-Small UDFN6 Footprint | 1.45 mm × 1.0 mm area - reduces PCB real estate by >50% vs. SC-88A, critical for wearables and hearing aids |
| Wide-Voltage Operation | 0.9 V minimum VCC - supports direct integration with energy-harvesting PMIC outputs and sub-1 V microcontroller I/O |
| Low Dynamic Power | CPD = 4 pF - limits switching power to <15 µW at 10 MHz/3.3 V, extending battery life in always-on wake-up circuits |
| Extended Temperature Range | −55°C to +125°C operation - meets AEC-Q200 stress test requirements for automotive body electronics |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DBVR | SC-70-5 package (2.0 mm × 1.25 mm); 3.6 V max VCC; no 4.6 V OVT input | Requires external clamping for >3.6 V inputs; larger footprint increases trace inductance | Select when board space permits larger package and input voltage stays ≤3.6 V |
| 74LVC1G17GW,125 | SC-88A package (2.2 mm × 1.35 mm); Schmitt-trigger input; 3.6 V max VCC | Provides hysteresis for noisy environments but lacks overvoltage tolerance and has slower 3.7 ns tPD | Prefer for debouncing mechanical switches; avoid where 4.6 V transient immunity is required |
Compared with SN74LVC1G34DBVR and 74LVC1G17GW,125, the NL17SG34AMUTCG uniquely combines 4.6 V input tolerance, UDFN6 miniaturization, and sub-3 ns speed - making it the only choice for space-constrained, mixed-voltage, high-reliability signal conditioning where transient robustness is mandatory.

FAQ
What is the maximum input voltage the NL17SG34AMUTCG can tolerate?
The NL17SG34AMUTCG supports DC input voltages from −0.5 V to +4.6 V, independent of VCC level. This overvoltage tolerance allows safe interfacing with higher-voltage domains such as 3.3 V I/O or 4.2 V battery rails without external protection components. The specification is validated per JEDEC JESD78 latch-up testing and appears in the Maximum Ratings table of the official datasheet.
Does the NL17SG34AMUTCG require external pull-up or pull-down resistors on its inputs?
No, the NL17SG34AMUTCG does not require external pull-up or pull-down resistors on IN A. Its CMOS input structure has negligible leakage (≤1.0 µA) and defined VIH/VIL thresholds across the full 0.9–3.6 V VCC range. Pull resistors are only needed if the driving source is high-impedance or open-drain - which is not typical for standard logic drivers interfacing with NL17SG34AMUTCG.
Can the NL17SG34AMUTCG operate at 0.9 V supply and still meet timing specifications?
Yes, the NL17SG34AMUTCG is fully specified down to 0.9 V VCC. At this voltage, AC Electrical Characteristics show tPLH/tPHL ≤19.0 ns (max) with CL = 10 pF. While propagation delay increases versus higher VCC, all recommended operating conditions-including VIH, VIL, VOH, and VOL-are guaranteed across the full 0.9–3.6 V range, enabling reliable sub-1 V system integration.
What is the thermal pad configuration for the UDFN6 package of NL17SG34AMUTCG?
The NL17SG34AMUTCG in UDFN6 (Case 517AQ) has no exposed thermal pad. Pins 1 and 4 are No Connect (NC), and the bottom surface consists solely of molded compound. Thermal dissipation relies on copper traces connected to pins 3 (GND) and 6 (VCC). Layout guidelines recommend ≥25 mm² of 1 oz copper connected to GND via ≥4 thermal vias for optimal junction temperature control.
Is the NL17SG34AMUTCG pin-compatible with other variants in the NL17SG34 family?
No, the NL17SG34AMUTCG is not pin-compatible with SOT-953 or SC-88A variants. It uses a 6-pin UDFN6 layout (1-NC, 2-IN A, 3-GND, 4-NC, 5-OUT Y, 6-VCC), whereas SOT-953 and SC-88A use 5-pin topologies with different pin assignments (e.g., SC-88A: 1-NC, 2-IN A, 3-GND, 4-VCC, 5-OUT Y). PCB redesign is required when substituting between packages.
