Product details
Overview
NL37WZ17USG-Q from onsemi is a triple noninverting Schmitt-trigger buffer IC designed for noise-immune signal conditioning in automotive and industrial logic interfaces, operating from 1.65 V to 5.5 V, delivering 3.2 ns typical propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and overvoltage-tolerant inputs/outputs up to 5.5 V.
For engineers reviewing the NL37WZ17USG-Q datasheet, pinout, applications, or equivalent options, key selection considerations include Schmitt-trigger hysteresis (0.7 V typ at 5.5 V), AEC-Q100 qualification, US8 package thermal resistance (250 °C/W), and IOFF-enabled partial power-down protection in mixed-voltage systems.
Technical Context
The NL37WZ17USG-Q implements three independent noninverting buffers, each with Schmitt-trigger input thresholds (VT+ = 3.6 V, VT− = 1.9 V at VCC = 5.5 V) and 0.7 V hysteresis, enabling robust noise rejection in noisy environments. It supports tri-state operation and features IOFF circuitry that disables I/O leakage when VCC = 0 V.
Designed for wide-supply operation (1.65–5.5 V), it maintains consistent DC performance across temperature (−55 °C to +125 °C) and offers rail-to-rail output swing with VOH ≥ VCC − 0.1 V and VOL ≤ 0.55 V at 24 mA sink, while meeting AEC-Q100 Grade 1 requirements for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| tPD (Typ) | 3.2 ns at VCC = 5 V - Supports high-speed digital interface timing in real-time control loops and sensor preprocessing. |
| IOFF Support | Active at VCC = 0 V - Prevents back-powering and bus contention during partial power-down in multi-rail systems. |
| Drive Strength | ±24 mA at 3.0 V - Sufficient to directly drive multiple CMOS loads or small capacitive traces without buffering. |
| Input Hysteresis | 0.7 V at VCC = 5.5 V - Rejects >700 mV of noise on slow or noisy signals (e.g., mechanical switch inputs, analog sensor outputs). |
| ESD Rating | HBM: 2000 V - Meets automotive ESD robustness requirements per ISO 10605 and AEC-Q100. |
| Operating Temp | −55 °C to +125 °C - Qualified for under-hood and industrial control cabinet deployment. |

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 ECUs and industrial PLC modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Input Channel 1 | Schmitt-trigger input for first buffer; tolerant to 5.5 V regardless of VCC. |
| 2 (Y3) | Output Channel 3 | Noninverting buffered output corresponding to A3; supports tri-state when enabled. |
| 3 (A2) | Input Channel 2 | Schmitt-trigger input for second buffer; shares same hysteresis and threshold specs as A1/A3. |
| 4 (GND) | Ground Reference | Primary return path for supply current and logic reference; must be low-impedance for noise immunity. |
| 5 (Y2) | Output Channel 2 | Noninverting buffered output corresponding to A2; IOFF active when VCC = 0 V. |
| 6 (A3) | Input Channel 3 | Schmitt-trigger input for third buffer; electrically identical to A1 and A2. |
| 7 (Y1) | Output Channel 1 | Noninverting buffered output corresponding to A1; full drive strength available across VCC range. |
| 8 (VCC) | Positive Supply | Single supply input powering all three buffers; IOFF disables I/O leakage when unpowered. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.7 V hysteresis at 5.5 V to eliminate chatter on slow-rising signals like thermistor-based temperature sensing or limit switches. |
| Overvoltage-tolerant I/O | Accepts and drives up to 5.5 V regardless of VCC setting - enables safe interfacing with legacy 5 V sensors in 3.3 V systems. |
| IOFF partial power-down | Blocks I/O leakage paths when VCC = 0 V - critical for hot-plug and sleep-mode integrity in battery-powered modules. |
| AEC-Q100 qualified | Meets Grade 1 stress test requirements (−40 °C to +125 °C ambient) and PPAP documentation readiness for automotive Tier-1 sourcing. |
| Low dynamic power | CPD = 11 pF at 5.5 V enables <1 mW no-load power at 10 MHz - suitable for always-on diagnostic circuits. |

FAQ
What is the primary function of the NL37WZ17USG-Q?
The NL37WZ17USG-Q is a triple noninverting Schmitt-trigger buffer IC used to condition noisy digital signals-such as those from mechanical switches or analog sensors-by providing hysteresis-based noise immunity and rail-to-rail output drive. Its design ensures reliable logic-level translation across 1.65 V to 5.5 V supply rails, and it is explicitly qualified for automotive applications under AEC-Q100 Grade 1.
Does the NL37WZ17USG-Q support partial power-down operation?
Yes, the NL37WZ17USG-Q includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. This feature prevents back-powering and bus contention in multi-rail systems where some sections remain powered while others are shut down-a critical capability in automotive domain controllers and industrial PLCs using staggered power sequencing.
What is the input hysteresis voltage of the NL37WZ17USG-Q at 5.5 V supply?
At VCC = 5.5 V, the NL37WZ17USG-Q exhibits a typical input hysteresis voltage (VH) of 0.7 V, calculated as VT+ − VT− = 3.6 V − 2.9 V. This value is confirmed in the DC Electrical Characteristics table and enables robust rejection of noise spikes exceeding 700 mV on slow-rising or EMI-prone signals-key for reliable switch debouncing and analog threshold detection.
Is the NL37WZ17USG-Q pin-compatible with standard US8-packaged logic devices?
The NL37WZ17USG-Q uses the standard US8 (Case 493) package with 0.5 mm pitch and defined pin 1 orientation (Q4 marking), matching industry-standard footprint dimensions. However, pin assignment (A1/Y3/A2/GND/Y2/A3/Y1/VCC) is specific to this device and not interchangeable with generic US8 logic ICs-PCB layout must follow the exact pinout shown in Figure 2 of the NL37WZ17USG-Q datasheet.
What automotive qualification does the NL37WZ17USG-Q hold?
The NL37WZ17USG-Q is AEC-Q100 qualified and PPAP capable, specifically meeting Grade 1 requirements (operating ambient temperature range −40 °C to +125 °C) and passing stress tests including HTOL, TCT, and ESD per JESD22 standards. The "−Q" suffix denotes dedicated automotive process controls, site-specific change management, and full traceability required by Tier-1 automotive suppliers.
