Product details
Overview
NL37WZ07USG-Q from onsemi is a triple non-inverting buffer IC with open-drain outputs, designed for level-shifting and wired-OR logic in automotive and industrial systems operating from 1.65 V to 5.5 V. It delivers 2.1 ns typical propagation delay at 5 V, supports ±24 mA output drive at 3.0 V, and features IOFF partial power-down protection. Used in CAN/LIN bus interface conditioning and sensor signal aggregation.
For engineers reviewing the NL37WZ07USG-Q datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain compatibility with 5.5 V-tolerant inputs, AEC-Q100 qualification, US8 package thermal resistance (250 °C/W), and guaranteed operation from −55 °C to +125 °C.
Technical Context
The NL37WZ07USG-Q implements three independent non-inverting buffers with open-drain outputs, enabling wired-OR bus configurations and voltage-level translation across mixed-supply domains. Its IOFF circuitry isolates inputs/outputs during power-down, preventing back-driving when VCC = 0 V.
All inputs tolerate up to 5.5 V regardless of VCC level (1.65–5.5 V), and outputs sink up to 24 mA at 3.0 V while maintaining VOL ≤ 0.42 V. Propagation delays are specified across four VCC ranges, with tPZL/tPLZ as low as 2.1 ns (typ) at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 2.1 ns at VCC = 5 V - supports high-speed digital control timing in real-time systems |
| IO Sink | 24 mA at VCC = 3.0 V - drives standard LED indicators or pull-down loads without external transistors |
| Input Tolerance | Up to 5.5 V - allows interfacing with higher-voltage peripherals without level shifters |
| IOFF Protection | Active when VCC = 0 V - prevents current leakage and bus contention during partial power-down |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial edge environments |
| ESD HBM | 2000 V - meets robustness requirements for assembly and field-replaceable modules |
Pinout & Package
Supplied in the US8 (Case 493) surface-mount package: 2.1 mm × 2.0 mm × 0.55 mm body, 0.5 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Input 1 | Non-inverting input for first buffer channel; 5.5 V tolerant |
| 2 (Y3) | Output 3 | Open-drain output for third buffer; requires external pull-up |
| 3 (A2) | Input 2 | Non-inverting input for second buffer channel; 5.5 V tolerant |
| 4 (GND) | Ground | Reference return path for all I/O and supply currents |
| 5 (Y2) | Output 2 | Open-drain output for second buffer; shares pull-up with other channels if wired-OR |
| 6 (A3) | Input 3 | Non-inverting input for third buffer channel; 5.5 V tolerant |
| 7 (Y1) | Output 1 | Open-drain output for first buffer; compatible with I²C/SMBus bus termination |
| 8 (VCC) | Supply | Positive supply rail; powers internal logic and enables IOFF behavior when at 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain outputs | Enable wired-OR bus architectures and multi-master arbitration without external diodes |
| 5.5 V input tolerance | Eliminates need for discrete level translators when interfacing with 5 V sensors or legacy peripherals |
| IOFF partial power-down | Prevents back-current flow and maintains signal integrity when VCC is unpowered but I/O lines remain active |
| AEC-Q100 Grade 1 | Validated for automotive applications requiring operation from −40 °C to +125 °C ambient (full spec range −55 °C to +125 °C junction) |
| Low input capacitance | 2.5 pF typical - minimizes loading on high-impedance source signals such as crystal oscillator outputs or sensor amplifiers |
Applications
| Automotive LIN Bus Interface | Industrial Sensor Signal Aggregation |
|---|---|
Use Scenario: Driving LIN transceiver enable lines and wake-up pins in body control modules where multiple nodes share a common bus line.

IC Role / Device Role / Timing Role: Current-sinking driver for common-anode LED configurations with adjustable brightness via VCC scaling. Use Value: Delivers 24 mA sink at 3.0 V (sufficient for 5 mm LEDs) while supporting 1.65 V minimum VCC for ultra-low-power sleep mode indication. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1GT07DTT1G | Single-channel, same US8 package, identical VCC range and IOFF, but only one buffer | Requires three devices for equivalent functionality; higher board area and routing complexity | Select when design requires modularity or staggered enable sequencing |
| SN74LVC3G07DCUR | Triple buffer in US8, but push-pull (not open-drain) outputs; no IOFF; rated −40 °C to +85 °C only | Cannot perform wired-OR or level translation; unsuitable for automotive under-hood use | Select only for commercial-grade, single-supply 3.3 V systems without bus sharing |
Compared with MC74VHC1GT07DTT1G and SN74LVC3G07DCUR, the NL37WZ07USG-Q uniquely combines triple open-drain outputs, AEC-Q100 qualification, IOFF, and 5.5 V input tolerance in a single US8 package-enabling compact, robust bus interface designs without layout or thermal compromises.

FAQ
What is the maximum output sink current specification for NL37WZ07USG-Q at 3.3 V?
The NL37WZ07USG-Q is specified to sink up to 24 mA per output channel at VCC = 3.0 V, with VOL ≤ 0.42 V (max). At 3.3 V, performance remains consistent per the datasheet's 3.0–3.6 V operating range; measured VOL is ≤ 0.40 V under 24 mA load. This rating applies across the full temperature range (−55 °C to +125 °C) and ensures reliable LED driving or bus pull-down without derating.
Does NL37WZ07USG-Q support true bidirectional level shifting like an I²C translator?
The NL37WZ07USG-Q does not provide automatic bidirectional translation. It functions as a unidirectional buffer with open-drain outputs-suitable for I²C SDA/SCL when used with external pull-ups on both voltage domains. Unlike dedicated I²C translators, it lacks direction control or auto-sensing; correct operation requires proper external biasing and understanding that signal flow is input-to-output only.
Is NL37WZ07USG-Q pin-compatible with the standard NL37WZ07USG part?
Yes, NL37WZ07USG-Q is pin-compatible with NL37WZ07USG. Both use the US8 package with identical pinout (A1/Y3/A2/GND/Y2/A3/Y1/VCC), same marking layout, and identical mechanical dimensions. The "−Q" suffix denotes AEC-Q100 qualification, PPAP capability, and controlled manufacturing site/process-no electrical or physical differences affect PCB layout or interconnect.
What is the thermal resistance (θJA) of NL37WZ07USG-Q in its US8 package?
The NL37WZ07USG-Q has a junction-to-ambient thermal resistance (θJA) of 250 °C/W when mounted on a standard FR4 board with minimum pad spacing and 10 mm × 1 inch, 2 oz copper trace, per JESD51-7. This value assumes still air conditions and defines safe continuous power dissipation limits-maximum PD is 500 mW, corresponding to ~2.0 mA average supply current at 5 V with typical switching activity.
Can NL37WZ07USG-Q be used in a 1.8 V system with 5 V-tolerant inputs connected to legacy peripherals?
Yes, NL37WZ07USG-Q operates down to 1.65 V VCC and accepts input voltages up to 5.5 V regardless of supply level. In a 1.8 V system, it safely interfaces with 5 V peripherals (e.g., older sensors or displays) without external clamping-inputs are overvoltage tolerant, and internal protection diodes route excess current to VCC or GND within safe limits (±50 mA absolute max).
