Product details
Overview
NL17SG14DFT2G-Q from onsemi is a single-channel Schmitt-trigger inverter IC designed for ultra-low-voltage digital signal conditioning in space-constrained applications. It operates from 0.9 V to 3.6 V, delivers 2.4 ns typical propagation delay at 3.0 V/15 pF, supports input/output overvoltage tolerance up to 3.6 V, features IOFF partial power-down protection, and is qualified to AEC-Q100 Grade 1 for automotive use.
For engineers reviewing the NL17SG14DFT2G-Q datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SC-88A package mapping, confirmed Schmitt-trigger hysteresis values across supply range, real-world timing performance at multiple VCC/CL conditions, and two technically documented alternative parts with precise differentiation.
Technical Context
The NL17SG14DFT2G-Q implements a single CMOS inverter with hysteresis-based Schmitt-trigger inputs to reject noise on slow-rising or noisy digital signals. Its input threshold voltages (VT+ = 0.75–2.24 V, VT− = 0.15–1.13 V) and hysteresis (VH = 0.27–1.1 V) are fully specified across 0.9–3.6 V supply and −55°C to +125°C temperature range.
It supports tri-state-compatible operation via IOFF leakage control (<10 µA at VCC = 0 V), enables mixed-voltage interfacing with 3.6 V tolerant I/O pins independent of VCC, and maintains guaranteed switching performance down to 0.9 V supply-critical for battery-powered and multi-rail systems.
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 domains without level shifters. |
| tPLH/tPHL (Typ) | 2.4 ns at VCC = 3.0 V, CL = 15 pF - Supports >200 MHz signal edge rates in clean digital paths. |
| Input Hysteresis (VH) | 0.49 V min at VCC = 3.0 V - Provides robust noise immunity against ≥500 mV peak-to-peak interference. |
| IOFF Leakage | <10 µA at VCC = 0 V - Prevents back-driving and signal corruption during partial power-down sequences. |
| I/O Voltage Tolerance | Up to 3.6 V - Allows safe connection to higher-voltage buses even when VCC = 0.9 V. |
| Operating Temp | −55°C to +125°C - Validated for under-hood automotive, industrial control, and extended-environment deployments. |
| ESD Rating | HBM 2000 V, CDM 1000 V - Meets standard handling requirements for automated SMT assembly lines. |
Pinout & Package
The NL17SG14DFT2G-Q is supplied in the SC-88A (SOT-353) 5-pin surface-mount package, measuring 2.1 mm × 1.25 mm × 0.95 mm, with lead-free (Pb-free) finish and moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC (No Connect) | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 | Input (A) | Schmitt-trigger input accepting 0–3.6 V logic levels; hysteresis ensures stable transition despite slow edges or noise. |
| 3 | GND | Dedicated ground reference for both input threshold generation and output driver return path. |
| 4 | VCC | Single positive supply rail (0.9–3.6 V); powers internal logic and output stage; IOFF active when VCC = 0 V. |
| 5 | Output (Y) | Inverted Schmitt-trigger output; drives CMOS loads up to ±20 mA; compatible with 1.2–3.3 V logic families. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low-Voltage Operation | Functional down to 0.9 V supply - enables integration into energy-harvesting and coin-cell-powered sensor nodes. |
| Input Overvoltage Tolerance | Withstands 3.6 V inputs regardless of VCC setting - eliminates need for external clamping diodes in mixed-supply systems. |
| IOFF Partial Power-Down | Blocks current flow between powered and unpowered sections - essential for hot-swap and modular system architectures. |
| AEC-Q100 Qualified | Grade 1 (−40°C to +125°C ambient) qualification with PPAP capability - meets automotive electronics reliability and traceability requirements. |
| Small Footprint Packaging | SC-88A package occupies only 2.6 mm² board area - ideal for wearables, TWS earbuds, and compact IoT modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G14DTT1G | Wider VCC range (2.0–5.5 V); no sub-1.0 V operation; higher propagation delay (4.5 ns typ @ 3.3 V) | Not suitable for 0.9–1.2 V systems; requires minimum 2.0 V supply | Select only if operating above 2.0 V and legacy footprint compatibility with SOIC-5 or SC-70 is required. |
| SN74LVC1G14DBVR | Same 1.65–5.5 V VCC range; IOFF not supported; lower hysteresis (0.2 V typ @ 3.3 V) | Lacks partial power-down protection; reduced noise margin in high-noise environments | Prefer for cost-sensitive non-automotive applications where full power-down isolation is unnecessary. |
Compared with MC74VHC1G14DTT1G and SN74LVC1G14DBVR, the NL17SG14DFT2G-Q uniquely supports 0.9 V operation, delivers faster timing at low voltage, includes IOFF for system-level power sequencing, and carries AEC-Q100 qualification - making it the only choice for automotive-grade, ultra-low-voltage Schmitt inverter applications.

FAQ
What is the minimum supply voltage at which NL17SG14DFT2G-Q guarantees correct Schmitt-trigger operation?
The NL17SG14DFT2G-Q guarantees full functional operation-including specified input thresholds, hysteresis, and propagation delay-from VCC = 0.9 V to 3.6 V, as confirmed in Table 2 (Recommended Operating Conditions) and Table 3 (DC Electrical Characteristics) of the official onsemi datasheet. Below 0.9 V, behavior is not characterized or guaranteed. The NL17SG14DFT2G-Q is explicitly designed for sub-1.0 V compatibility in modern ultra-low-power systems.
Does NL17SG14DFT2G-Q support true tri-state output functionality?
No, the NL17SG14DFT2G-Q does not provide tri-state output control. It is a fixed-function inverter with push-pull CMOS output. However, it features IOFF (power-off isolation), which disables current conduction between input and output when VCC = 0 V-preventing back-driving in partial power-down scenarios. This is distinct from active tri-state control but serves a related system-level isolation purpose.
What is the pin 1 marking orientation for NL17SG14DFT2G-Q in SC-88A packaging?
Per the onsemi ordering information table (page 6), the NL17SG14DFT2G-Q in SC-88A package uses marking "AR" and has pin 1 located in quadrant 3 of the tape-and-reel carrier. On the physical device, pin 1 is identified by a dot or notch adjacent to the terminal at the top-left corner when the marking side faces up and the leads point downward.
Is NL17SG14DFT2G-Q compatible with reflow soldering processes for lead-free assembly?
Yes, the NL17SG14DFT2G-Q is Pb-free and RoHS-compliant, with a maximum lead temperature rating of 260°C for 10 seconds (Table 1, Maximum Ratings). Its SC-88A package is qualified for standard lead-free reflow profiles including J-STD-020, and the device carries MSL Level 1 rating-meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly.
How does the hysteresis of NL17SG14DFT2G-Q vary with supply voltage?
The NL17SG14DFT2G-Q hysteresis (VH) increases with VCC: it is 0.27 V typical at 0.9 V, 0.49 V at 3.0 V, and up to 1.1 V maximum at 3.6 V (Table 3). This voltage-scaling behavior ensures consistent noise margin percentage-wise across its full operating range-e.g., ~30% of VCC at mid-range supplies-making it adaptable to diverse rail voltages without recalibration.
