Product details
Overview
NL37WZ04US from onsemi is a triple CMOS inverter IC operating from 1.65 V to 5.5 V, delivering 2.3 ns typical propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and overvoltage-tolerant I/O up to 5.5 V. It serves as a high-speed logic-level shifter and signal conditioning element in automotive body control modules requiring AEC-Q100 qualification.
For engineers reviewing the NL37WZ04US datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (1.65–5.5 V), IOFF-enabled partial power-down protection, tri-state-compatible output behavior, and US8 package thermal performance (250 °C/W).
Technical Context
The NL37WZ04US implements three independent CMOS inverter stages in a single US8 package, each with rail-to-rail input thresholds defined by VCC-dependent VIH/VIL (e.g., 0.70×VCC min for VIH at VCC ≥ 2.3 V). Its IOFF circuitry disables I/O leakage paths when VCC = 0 V, enabling live insertion and hot-swap compatibility in multi-rail systems.
Propagation delay varies with supply voltage and load: 1.8–2.8 ns (typ) at 4.5–5.5 V with 15 pF load; 2.2–3.4 ns (typ) at 3.0–3.6 V. Output drive strength is specified across VCC range - VOL ≤ 0.28 V at IOL = 12 mA and VCC = 3.0 V, VOH ≥ 2.4 V at IOH = −12 mA and VCC = 3.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports mixed-voltage interface between 1.8 V, 2.5 V, 3.3 V, and 5 V domains without level shifters |
| tPD (Typ) | 2.3 ns at VCC = 5 V, CL = 15 pF - enables sub-200 MHz clock/data path timing in compact logic functions |
| I/O Overvoltage | Up to 5.5 V - allows safe interfacing with higher-voltage peripherals even when VCC = 1.65 V |
| IOFF Support | Active at VCC = 0 V - prevents back-powering and signal contention during partial system shutdown |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74-series inputs |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| Package | US8 (Case 493) - 2.1 mm × 2.0 mm × 0.55 mm surface-mount footprint with 0.5 mm pitch, optimized for space-constrained PCBs |
Pinout & Package
US8 package: 2.1 mm × 2.0 mm × 0.55 mm body, 0.5 mm lead pitch, exposed pad not present, moisture sensitivity level 1, RoHS-compliant Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | Inverter 1 input - accepts 1.65–5.5 V logic signals regardless of VCC value |
| 2 | Y3 | Inverter 3 output - active-low inversion of A3; supports bus hold and IOFF isolation |
| 3 | A2 | Inverter 2 input - electrically identical to A1 and A3; no internal coupling |
| 4 | GND | Ground reference - must be connected before VCC during power sequencing to avoid latchup |
| 5 | Y2 | Inverter 2 output - drives loads up to 24 mA sink/source at 3.0 V with <0.4 V VOL |
| 6 | A3 | Inverter 3 input - tolerant to 5.5 V inputs while VCC = 1.65 V, enabling level translation |
| 7 | Y1 | Inverter 1 output - matches Y2/Y3 electrical specs; all outputs share same DC/AC characteristics |
| 8 | VCC | Positive supply - powers all three inverters; IOFF activates when VCC = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input threshold tracking | VIH/VIL scale with VCC (e.g., 0.70×VCC min VIH), ensuring consistent noise margin across 1.65–5.5 V operation |
| IOFF partial power-down | Blocks >99% I/O leakage current when VCC = 0 V, preventing unintended biasing of downstream circuits |
| Overvoltage-tolerant I/O | Withstands 5.5 V on any input or output pin independent of VCC, eliminating need for external clamping diodes |
| Low dynamic power | CPD = 9–11 pF enables <1 mW no-load power at 10 MHz and 3.3 V, reducing thermal load in dense layouts |
| AEC-Q100 qualified | Qualified to Grade 1 (−40 °C to +125 °C ambient) with PPAP documentation support for automotive production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC14DT | Schmitt-trigger inputs (hysteresis ~0.3 V), 2.5 ns tPD at 5 V, SOIC-14 package only | Requires external pull-ups for open-drain compatibility; unsuitable where linear threshold tracking is needed | Select when noise immunity on slow-rising signals is critical; avoid if VCC-scaling VIH/VIL is required |
| SN74LVC3G04DCU | Same US8 package, 2.5 ns tPD at 3.3 V, but only 1.65–5.5 V VCC and no AEC-Q100 qualification | Lacks IOFF and automotive qualification; lower drive (±24 mA only at VCC ≥ 4.5 V) | Select for cost-sensitive industrial designs without automotive compliance requirements |
Compared with MC74VHC14DT and SN74LVC3G04DCU, the NL37WZ04US uniquely combines AEC-Q100 qualification, IOFF-enabled partial power-down, and VCC-scaled input thresholds - making it the only choice for automotive body electronics requiring guaranteed operation across 1.65–5.5 V with zero-layout changes during domain power sequencing.

FAQ
What is the maximum operating temperature for the NL37WZ04US?
The NL37WZ04US is rated for operation from −55 °C to +125 °C ambient temperature and is AEC-Q100 qualified for automotive Grade 1 applications. Its junction temperature limit is +150 °C, and thermal resistance (θJA) is 250 °C/W in the US8 package on standard FR4 PCB layout - confirming suitability for under-hood deployment where sustained 105 °C ambient is common. The NL37WZ04US maintains full DC/AC specifications across this full range.
Does the NL37WZ04US support partial power-down mode?
Yes, the NL37WZ04US supports partial power-down via its IOFF feature: when VCC = 0 V, input and output leakage currents are limited to ≤10 µA, effectively isolating the device from live signal lines. This prevents back-driving of powered domains and enables hot-swap capability in modular systems. The NL37WZ04US implements this at the transistor level - no external control signals or enable pins are required.
Can the NL37WZ04US safely interface a 5 V sensor with a 1.8 V microcontroller?
Yes, the NL37WZ04US can safely interface a 5 V sensor with a 1.8 V microcontroller: its inputs tolerate up to 5.5 V regardless of VCC, and its outputs swing rail-to-rail (0 V to VCC), so with VCC = 1.8 V, Y1/Y2/Y3 deliver true 1.8 V logic levels. Input thresholds scale with VCC (VIH ≥ 0.65×VCC), ensuring robust noise margin. The NL37WZ04US thus acts as a bidirectional level translator without external components.
What is the propagation delay variation of the NL37WZ04US across supply voltage?
The NL37WZ04US propagation delay varies predictably with VCC: 4.4–9.5 ns (max) at 1.65–1.95 V, 5.0–6.1 ns (max) at 2.3–2.7 V, 2.2–3.8 ns (max) at 3.0–3.6 V, and 1.8–3.1 ns (max) at 4.5–5.5 V, all measured at CL = 15 pF. This monotonic reduction confirms stable high-speed operation across its full 1.65–5.5 V range - a key differentiator versus fixed-VCC logic families. The NL37WZ04US delivers consistent timing margins in multi-rail systems.
Is the NL37WZ04US pin-compatible with other triple inverter packages?
No, the NL37WZ04US in US8 package is not pin-compatible with industry-standard SOIC-14 or TSSOP-14 triple inverters like the 74HC04 or 74LVC04. Its US8 pinout (A1-Y3-A2-GND-Y2-A3-Y1-VCC) is unique to onsemi's ultra-small logic portfolio. However, the NL37WZ04US provides functional equivalence - three independent inverters - and its compact 2.1 mm × 2.0 mm footprint enables board area savings versus larger packages. The NL37WZ04US requires dedicated layout but offers superior density and thermal performance.
