Product details
Overview
NLV17SZ14DFT2G from onsemi is a single Schmitt-trigger inverter IC designed for signal conditioning and noise-immune digital logic inversion in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 3.7 ns typical propagation delay at 5 V, supports ±24 mA I/O drive at 3.0 V, and features IOFF partial power-down protection - used in industrial sensor interfaces, automotive body control modules, and portable MCU reset circuits.
For engineers reviewing the NLV17SZ14DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 5-pin SC-88A package, Schmitt-trigger hysteresis (0.48 V typ at 1.65 V), input overvoltage tolerance up to 5.5 V, and AEC-Q100 qualification for automotive use cases requiring robust noise immunity and rail-to-rail compatibility.
Technical Context
The NLV17SZ14DFT2G implements a single CMOS inverter with Schmitt-trigger input thresholds (VT+ = 1.4 V, VT− = 0.5 V at 1.65 V) to reject analog noise on slow or noisy digital signals. Its IOFF circuitry disables I/O leakage when VCC = 0 V, enabling live insertion and hot-swap capability in multi-rail systems.
It supports rail-to-rail operation across 1.65–5.5 V supply range, maintains consistent hysteresis (0.48–1.7 V) and propagation delay (3.1–15.6 ns) across voltage and temperature (−55 °C to +125 °C), and exhibits low input capacitance (2.5 pF) and power dissipation capacitance (9–11 pF) for high-speed, low-power interfacing.
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) | 3.7 ns at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - ensures fast signal inversion for timing-critical edge detection. |
| IOFF Support | Active power-down isolation - prevents back-driving and leakage when VCC is unpowered, critical for system-level hot-swap compliance. |
| Input Hysteresis | 0.48 V (min) at 1.65 V - rejects >480 mV of noise on input transitions, eliminating false triggering in EMI-prone environments. |
| I/O Drive | ±24 mA at VCC = 3.0 V - directly drives LEDs, small relays, or multiple standard-load CMOS inputs without external buffers. |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets industrial and automotive board-level ESD robustness requirements per JEDEC standards. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial control, and extended-temperature embedded applications. |
Pinout & Package
Package: SC-88A (Case 419A), 5-pin surface-mount, 2.1 mm × 1.25 mm × 0.95 mm footprint with 0.65 mm pitch - optimized for high-density PCB layouts in compact consumer and automotive modules.
| 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 | Input (A) | Schmitt-trigger input - accepts 0–5.5 V logic signals regardless of VCC; immune to slow edges and noise. |
| 3 | GND | Ground reference - provides return path for all internal logic and I/O current; requires low-impedance PCB connection. |
| 4 | Output (Y) | Inverted Schmitt output - actively driven high/low with rail-to-rail swing and 24 mA sink/source capability at 3 V. |
| 5 | VCC | Positive supply - powers internal logic; supports IOFF behavior when de-energized; decoupling capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.48–1.7 V hysteresis to eliminate chatter on slow or noisy signals - essential for switch debouncing and analog sensor digitization. |
| IOFF partial power-down | Blocks I/O leakage (<1.0 µA) when VCC = 0 V - enables safe hot-plug operation and prevents bus contention in multi-supply systems. |
| Rail-to-rail I/O tolerance | Accepts and outputs up to 5.5 V independent of VCC - simplifies interfacing with mixed-voltage peripherals and legacy 5 V sensors. |
| Low dynamic power | CPD = 9–11 pF - minimizes switching current (ICC(OPR) = CPD × VCC² × f + ICC), reducing heat and supply ripple at 10 MHz operation. |
| AEC-Q100 qualified | Qualified to Grade 1 (−40 °C to +125 °C) and PPAP-capable - meets automotive electronics reliability and traceability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1GT14DTT1G | Same SC-88A package, 2.0–5.5 V VCC range, 3.5 ns tPD at 5 V, but lacks IOFF and AEC-Q100 qualification. | Not suitable for hot-swap or automotive applications requiring power-down isolation or PPAP documentation. | Select when cost sensitivity outweighs automotive qualification and IOFF requirement; verify system-level power sequencing. |
| SN74LVC1G14DBVR | SC-74A package (larger than SC-88A), 1.65–5.5 V, 4.5 ns tPD at 3.3 V, IOFF supported, but not AEC-Q100 qualified. | Acceptable for industrial use but requires rework for automotive deployment due to missing qualification and different footprint. | Choose if SC-74A is already standardized in design; confirm thermal derating (JA = 320 °C/W vs. NLV17SZ14DFT2G's 377 °C/W). |

FAQ
What is the pin configuration of the NLV17SZ14DFT2G?
The NLV17SZ14DFT2G uses a 5-pin SC-88A package with pinout: Pin 1 = NC, Pin 2 = Input (A), Pin 3 = GND, Pin 4 = Output (Y), Pin 5 = VCC. This configuration is confirmed in Figure 2 and the PIN ASSIGNMENT table of the official datasheet (Rev. 20, January 2026). Pin 1 is internally unconnected and must remain floating or grounded per layout guidelines.
Does the NLV17SZ14DFT2G support partial power-down functionality?
Yes, the NLV17SZ14DFT2G supports IOFF partial power-down protection. When VCC = 0 V, the input and output ports enter a high-impedance state with leakage current limited to ≤10 µA (max), preventing back-driving and bus contention. This feature is explicitly specified in the datasheet Features section and DC Electrical Characteristics table under IOFF parameter.
Is the NLV17SZ14DFT2G qualified for automotive applications?
Yes, the NLV17SZ14DFT2G is AEC-Q100 qualified and PPAP capable. The "−Q" suffix variant (NLV17SZ14DFT2G-Q) is explicitly designated for automotive use, and the base part shares the same qualification. It meets Grade 1 temperature range (−40 °C to +125 °C), ESD (HBM 2000 V), and latch-up (100 mA) requirements defined in the datasheet's Maximum Ratings and Features sections.
What is the typical propagation delay of the NLV17SZ14DFT2G at 3.3 V?
The typical propagation delay (tPLH/tPHL) of the NLV17SZ14DFT2G is 4.4 ns at VCC = 3.3 V, RL = 500 Ω, and CL = 50 pF, as specified in the AC Electrical Characteristics table (page 5). At 3.0 V with RL = 1 MΩ and CL = 15 pF, it is 3.7 ns (typ). These values are measured under defined load conditions and vary with voltage, temperature, and capacitive loading.
Can the NLV17SZ14DFT2G accept 5 V input signals while operating from a 3.3 V supply?
Yes, the NLV17SZ14DFT2G supports input overvoltage tolerance up to 5.5 V regardless of VCC level - meaning it can safely accept 5 V logic inputs while powered from 1.65–5.5 V, including 3.3 V. This is confirmed in the Features list and DC Electrical Characteristics table under VIN specification (0 to 5.5 V), enabling direct interfacing with legacy 5 V peripherals.
