Product details
Overview
NL17SZ14DFT2G-L22038 from onsemi is a single Schmitt-trigger inverter IC in SC-88A (SOT-353) package, operating from 1.65 V to 5.5 V supply, delivering 3.7 ns propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and input overvoltage tolerance up to 5.5 V - used for noise-immune signal conditioning in low-power sensor interfaces and digital logic level translation.
For engineers reviewing the NL17SZ14DFT2G-L22038 datasheet, pinout, applications, or equivalent options, key selection considerations include hysteresis voltage (0.48 V typ at 1.65 V), IOFF partial power-down support, VCC/GND/NC/A/Y pin assignment, and compatibility with 1.65–5.5 V mixed-voltage systems.
Technical Context
The NL17SZ14DFT2G-L22038 implements a single CMOS inverter with Schmitt-trigger input thresholds (VT+ = 1.4 V, VT− = 0.5 V at VCC = 1.65 V), providing 0.9 V hysteresis to reject analog noise on slow-rising or noisy digital signals. Its IOFF feature enables bidirectional isolation during partial power-down states, preventing current backflow when VCC = 0 V.
It supports rail-to-rail input operation up to 5.5 V independent of VCC, and delivers VOH ≥ VCC − 0.1 V and VOL ≤ 0.28 V at IOL = 12 mA (VCC = 3.0 V), ensuring robust interfacing with legacy 3.3 V and 5 V logic families while maintaining low dynamic power via CPD = 9 pF at 3.3 V.
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 domains without level shifters |
| tPD (typ) | 3.7 ns at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - supports >100 MHz signal edge rates in timing-critical paths |
| Input Hysteresis | 0.48 V (min) at VCC = 1.65 V - rejects up to ±240 mV of superimposed noise on input transitions |
| IOFF Leakage | ≤10 μA at VCC = 0 V - prevents bus contention and power loss during system sleep modes |
| Output Drive | ±24 mA at VCC = 3.0 V - drives multiple 74LVC inputs or small capacitive loads (≤50 pF) without buffering |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets industrial-grade ESD immunity requirements without external protection |
| Operating Temp | −55 °C to +125 °C - qualified for extended-temperature automotive and industrial control environments |
Pinout & Package
SC-88A (Case 419A) package: 5-pin, 2.0 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch, moisture sensitivity level 1, Pb-free and RoHS compliant.
| 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 signals regardless of VCC; immune to slow edges and noise |
| 3 | GND | Ground reference - return path for all internal currents; requires low-impedance PCB connection |
| 4 | Output (Y) | Inverted output - actively driven high/low; supports IOFF tri-state behavior when VCC = 0 V |
| 5 | VCC | Positive supply - powers internal logic; decoupling capacitor (0.1 μF) required within 2 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.48–1.7 V hysteresis across VCC range - eliminates chatter on slow or noisy switch inputs |
| IOFF partial power-down | Blocks current flow between A and Y when VCC = 0 V - enables hot-plug and multi-rail power sequencing |
| Overvoltage-tolerant I/O | Accepts 0–5.5 V inputs and outputs even at VCC = 1.65 V - simplifies mixed-voltage interconnect design |
| Low dynamic power | CPD = 9 pF at 3.3 V - reduces switching current by >30% vs. standard inverters at 10 MHz operation |
| Small-footprint packaging | SC-88A (2.0 × 1.25 mm) - saves >60% board area vs. SOIC-5 while maintaining hand-solderability |
Applications
| Industrial Sensor Interface | Automotive Body Control |
|---|---|
Use Scenario: Conditioning output of mechanical switches, reed relays, or resistive position sensors exposed to EMI in factory automation panels. IC Role / Device Role / Timing Role: Schmitt-trigger inverter acting as noise-filtering buffer and logic-level translator between 5 V sensor output and 3.3 V microcontroller GPIO. Use Value: Eliminates false triggers caused by contact bounce or 50/60 Hz pickup; operates reliably across −40 °C to +85 °C ambient. |
Use Scenario: Debouncing door latch, hood, or trunk switch signals before feeding to body control module (BCM). IC Role / Device Role / Timing Role: Single inverter with IOFF isolating switch input from BCM during ignition-off sleep mode (VCC = 0 V). Use Value: Prevents battery drain via leakage through unpowered MCU pins; AEC-Q100 qualified version available (NL17SZ14DFT2G-Q). |
| Portable Medical Device | IoT Edge Node |
Use Scenario: Signal conditioning for low-power pulse oximeter LED driver enable lines subject to ESD and thermal drift. IC Role / Device Role / Timing Role: Inverting logic gate converting MCU active-low enable to active-high LED driver input with noise margin. Use Value: 1.65 V minimum VCC allows direct use with coin-cell-powered MCUs; 125 °C max junction temp supports sterilization cycles. |
Use Scenario: Level-shifting wake-up signals from ultra-low-power environmental sensors (e.g., humidity ICs) to 3.3 V host MCU. IC Role / Device Role / Timing Role: Voltage-tolerant inverter translating 1.8 V sensor interrupt to 3.3 V-compatible active-low wake signal. Use Value: No external level shifter needed; IOFF blocks reverse current when sensor sleeps but MCU remains powered. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Same SC-70-5 (SC-74A) footprint; 3.5 ns tPD at 3.3 V; no IOFF; max VCC = 5.5 V; hysteresis 0.3 V min | Lacks IOFF - unsuitable for partial power-down systems; lower hysteresis reduces noise margin in EMI-heavy environments | Select when cost is primary and full power sequencing is guaranteed; verify noise immunity in final layout |
| MC74VHC1G14DTT1G | SC-70-5 package; 7.5 ns tPD at 5 V; IOFF supported; VCC range 2.0–5.5 V; hysteresis 0.4 V min at 5 V | Narrower VCC min (2.0 V) excludes 1.8 V operation; slower propagation limits high-speed edge detection | Choose for legacy VHC compatibility or where higher drive strength (±50 mA) outweighs speed penalty |
Compared with SN74LVC1G14DBVR and MC74VHC1G14DTT1G, the NL17SZ14DFT2G-L22038 uniquely combines 1.65 V operation, 3.7 ns speed, and IOFF in SC-88A - making it optimal for space-constrained, mixed-voltage, and low-power-sleep designs where noise rejection and power-domain isolation are critical.

FAQ
What is the pin 1 orientation and marking for NL17SZ14DFT2G-L22038?
NL17SZ14DFT2G-L22038 uses SC-88A (Case 419A) packaging with pin 1 identified by a dot or beveled edge on the top surface. Marking consists of "LA" device code followed by date code (e.g., "LAXX"); the "G" suffix confirms Pb-free and RoHS compliance. Pin 1 is located at the bottom-left corner when the marking is read upright.
Does NL17SZ14DFT2G-L22038 support true tri-state operation?
No, NL17SZ14DFT2G-L22038 does not provide active tri-state control. It features IOFF (power-off isolation), which disables conduction between input and output only when VCC = 0 V - useful for partial power-down, but not for bus-sharing applications requiring dynamic high-impedance output control.
Can NL17SZ14DFT2G-L22038 interface directly with 5 V TTL logic while powered from 3.3 V?
Yes, NL17SZ14DFT2G-L22038 supports input overvoltage tolerance up to 5.5 V independent of VCC. When powered from 3.3 V, it safely accepts 5 V TTL inputs and produces 3.3 V-compatible outputs (VOH ≥ 3.2 V, VOL ≤ 0.28 V at 12 mA), eliminating need for external level shifters.
What is the maximum capacitive load NL17SZ14DFT2G-L22038 can drive while maintaining 3.7 ns propagation delay?
The 3.7 ns typical propagation delay for NL17SZ14DFT2G-L22038 is specified with CL = 15 pF and RL = 1 MΩ. Driving >30 pF increases tPD nonlinearly; for loads above 50 pF, delay exceeds 7.2 ns. For heavy loads, add series termination or buffer stage to preserve timing integrity.
Is NL17SZ14DFT2G-L22038 qualified for automotive applications?
The base NL17SZ14DFT2G-L22038 is not AEC-Q100 qualified. However, its automotive-grade variant NL17SZ14DFT2G-Q (same SC-88A package, "Q" suffix) is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C) and PPAP capable - recommended for body electronics, lighting, and infotainment subsystems.
