Product details
Overview
NL37WZ14US from onsemi is a triple Schmitt-trigger inverter IC designed for noise-immune signal conditioning in low-voltage digital systems, operating from 1.65 V to 5.5 V, delivering 2.6 ns typical propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and IOFF-enabled partial power-down protection - used in automotive sensor interface circuits, industrial control logic, and battery-powered microcontroller reset conditioning.
For engineers reviewing the NL37WZ14US datasheet, pinout, applications, or equivalent options, key selection criteria include Schmitt-trigger hysteresis (0.25–1.7 V), overvoltage-tolerant inputs/outputs (up to 5.5 V), AEC-Q100 qualification, US8 package thermal resistance (250 °C/W), and tri-state-compatible output behavior under power-down conditions.
Technical Context
The NL37WZ14US implements three independent Schmitt-trigger inverters in a single US8 package, each with asymmetric input thresholds (e.g., VT+ = 1.9 V / VT− = 1.5 V at VCC = 3.0 V) and 0.4 V minimum hysteresis, enabling robust noise rejection in slow-rising or noisy signal environments such as mechanical switch debouncing or analog sensor threshold detection.
It supports mixed-voltage system interfacing via overvoltage-tolerant I/O (up to 5.5 V regardless of VCC), features IOFF circuitry that disables current flow when VCC = 0 V, and maintains functional integrity across −55 °C to +125 °C - meeting automotive-grade reliability requirements per AEC-Q100 Grade 1.
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) | 2.6 ns at VCC = 5 V - supports high-speed timing-critical inversion in clock distribution or pulse shaping paths. |
| IOH/IOL | ±24 mA at VCC = 3.0 V - drives multiple standard CMOS loads or small LEDs without external buffers. |
| VIN/VOUT Tolerance | Up to 5.5 V - allows safe connection to higher-voltage buses or legacy peripherals even during brown-out conditions. |
| Hysteresis (VH) | 0.25–1.7 V depending on VCC - provides configurable noise margin for reliable edge detection in unclean signal environments. |
| IOFF Leakage | ≤10 µA - prevents back-powering or signal contention when VCC is off, critical for hot-swap and power-gated subsystems. |
Pinout & Package
Supplied in the US8 (Case 493) surface-mount package - 2.1 mm × 2.0 mm footprint, 0.5 mm pitch, 0.55 mm max height - optimized for space-constrained automotive and portable electronics PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Inverter 1 Input | Schmitt-trigger input for first inverter stage; accepts 0–5.5 V signals independent of VCC. |
| 2 (Y3) | Inverter 3 Output | Active-drive output of third inverter; sinks or sources up to 24 mA at 3.0 V. |
| 3 (A2) | Inverter 2 Input | Noise-immune input for second inverter; enables independent signal conditioning path. |
| 4 (GND) | Ground Reference | Common return path for all three inverters and internal bias networks; must be low-impedance. |
| 5 (Y2) | Inverter 2 Output | Output with identical drive strength and hysteresis as Y1/Y3; supports parallel load sharing. |
| 6 (A3) | Inverter 3 Input | Third Schmitt-trigger input; allows simultaneous triple-threshold signal processing. |
| 7 (Y1) | Inverter 1 Output | Primary output with full 24 mA drive; compatible with 74LVC-level fanout requirements. |
| 8 (VCC) | Positive Supply | Single supply rail powering all three inverters; IOFF activates automatically when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent hysteresis-controlled inverters enable simultaneous noise filtering of multiple asynchronous signals (e.g., encoder A/B/Z, pushbutton inputs, sensor alerts). |
| AEC-Q100 qualified (Grade 1) | Validated for automotive applications across −40 °C to +125 °C ambient, including PPAP-capable manufacturing traceability and stress testing. |
| Overvoltage-tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC setting - eliminates need for external clamping diodes in mixed-supply systems. |
| IOFF partial power-down | Input/output leakage drops to ≤10 µA when VCC = 0 V - prevents back-driving powered subsystems during sleep or fault states. |
| Pb-free, Halogen-free, RoHS-compliant | Meets global environmental compliance mandates without performance trade-offs; suitable for consumer, industrial, and automotive end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC14APWR | Higher drive (±24 mA at 3.3 V), but only rated to 3.6 V VCC max; no IOFF; not AEC-Q100 qualified. | Suitable for commercial-grade 3.3 V systems only; lacks automotive temperature range and power-down safety. | Select when cost sensitivity outweighs automotive qualification and mixed-voltage tolerance requirements. |
| MC74VHC14DR2G | Wider VCC range (2.0–5.5 V); lower hysteresis (0.1–0.3 V typ); no IOFF; not AEC-Q100 qualified. | Acceptable for industrial 5 V logic, but insufficient noise immunity for noisy automotive or sensor interfaces. | Choose only if legacy 5 V design compatibility is mandatory and hysteresis >0.4 V is not required. |
Compared with SN74LVC14APWR and MC74VHC14DR2G, the NL37WZ14US uniquely combines AEC-Q100 qualification, 1.65–5.5 V operation, IOFF, and ≥0.4 V hysteresis - making it the only option among the three validated for automotive body electronics requiring robustness across voltage brown-out, hot-swap, and EMI-prone environments.

FAQ
What is the minimum operating voltage for the NL37WZ14US?
The NL37WZ14US operates down to 1.65 V VCC, enabling compatibility with modern ultra-low-power microcontrollers and battery-backed systems during brown-out conditions. This specification is guaranteed across the full −55 °C to +125 °C temperature range and verified per onsemi's Recommended Operating Conditions table.
Does the NL37WZ14US support partial power-down functionality?
Yes, the NL37WZ14US includes IOFF circuitry that disables input and output current paths when VCC = 0 V, limiting leakage to ≤10 µA. This feature prevents back-powering of upstream or downstream circuitry - a critical requirement for hot-swap and power-gated architectures where the NL37WZ14US may remain connected while its supply is inactive.
Is the NL37WZ14US qualified for automotive applications?
Yes, the NL37WZ14US−Q variant is AEC-Q100 qualified (Grade 1) and PPAP capable. The "−Q" suffix denotes automotive-specific process controls, extended temperature validation (−40 °C to +125 °C), and enhanced traceability - confirming its suitability for use in body control modules, lighting controllers, and other non-safety-critical automotive ECUs.
What is the input hysteresis voltage of the NL37WZ14US at 3.3 V supply?
At VCC = 3.3 V, the NL37WZ14US exhibits a typical input hysteresis (VH) of 0.93 V, with a minimum of 0.75 V and maximum of 1.15 V across temperature. This wide hysteresis band ensures reliable switching in presence of noise up to ±465 mV, making the NL37WZ14US especially effective for mechanical switch debouncing and analog comparator output conditioning.
Can the NL37WZ14US interface with 5 V logic while powered from 3.3 V?
Yes, the NL37WZ14US features overvoltage-tolerant inputs and outputs rated to 5.5 V regardless of VCC level. When powered from 3.3 V, it safely accepts 5 V input signals and drives 5 V-tolerant loads without damage or level-shifting components - a key advantage over standard LVC or HC logic families that require external protection.
