Product details
Overview
NL37WZ16USG-Q from onsemi is a triple non-inverting buffer IC designed for high-speed, low-voltage logic interfacing in automotive and industrial systems. It operates from 1.65 V to 5.5 V, delivers 2.4 ns typical propagation delay at 5 V, supports ±24 mA drive strength at 3.0 V, and features IOFF partial power-down protection. It is used in signal conditioning paths between mixed-voltage domains in engine control units and body electronics.
For engineers reviewing the NL37WZ16USG-Q datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, overvoltage-tolerant inputs/outputs up to 5.5 V, US8 package footprint, tri-state capability per channel, and guaranteed operation from −55 °C to +125 °C.
Technical Context
The NL37WZ16USG-Q implements three independent CMOS buffer stages with Schmitt-trigger–free inputs and push-pull outputs. Each channel supports true tri-state operation via individual input control (A1–A3), enabling dynamic bus isolation without external logic.
Its IOFF circuitry disables output leakage when VCC = 0 V, preventing back-driving of powered subsystems during partial power-down sequences. The device uses <100 FETs per buffer and meets AEC-Q100 Grade 1 requirements for automotive under-hood applications.

Use Scenario: Level-shifting sensor signals (e.g., knock sensor analog front-end outputs) from 5 V microcontroller peripherals to 3.3 V ADC inputs in real-time engine monitoring. IC Role / Device Role / Timing Role: Triple buffer provides noise-immune, low-latency signal pass-through with independent enable control per channel to gate diagnostic data streams. Use Value: 2.4 ns tPD ensures timing-critical feedback loops remain closed within 10 ns budget; overvoltage tolerance avoids external protection components. | Use Scenario: Isolating LIN bus transceiver I/O lines from MCU GPIOs during sleep mode in door module controllers to reduce quiescent current. IC Role / Device Role / Timing Role: Acts as bi-directional buffer with IOFF support, enabling zero-leakage disconnection when main VCC is removed while LIN bias remains active. Use Value: IOFF leakage ≤10 µA prevents battery drain; AEC-Q100 qualification guarantees reliability over 15-year vehicle lifetime. |
| Instrument Cluster Display Interface | ADAS Camera Module Power Sequencing |
Use Scenario: Driving parallel RGB data lines from a 3.3 V video processor to a 5 V display timing controller with matched skew across all three channels. IC Role / Device Role / Timing Role: Synchronous triple buffer ensures <0.5 ns inter-channel skew between R/G/B signals, preserving pixel alignment integrity. Use Value: Matched tPLH/tPHL across channels minimizes color fringing; ±24 mA drive sustains signal integrity over 10 cm FR4 traces. | Use Scenario: Enabling controlled power-up sequence for MIPI CSI-2 serializer ICs by buffering reset and clock enable signals from a 1.8 V PMIC to 2.8 V image sensor rails. IC Role / Device Role / Timing Role: Provides voltage-agnostic signal buffering with precise timing margin control during multi-rail power-on reset coordination. Use Value: 1.65 V minimum VCC allows direct interface with ultra-low-power PMICs; −55 °C to +125 °C range covers cold-start to thermal soak conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC125DTG | Quad buffer (4 channels), no IOFF, VCC min = 2.0 V, tPD = 3.5 ns @ 5 V | Lacks partial power-down; not AEC-Q100 qualified; requires ≥2.0 V VCC | Use where quad count is needed and automotive qualification is unnecessary. |
| SN74LVC3G17DCUR | Triple Schmitt-trigger buffer, no IOFF, VCC = 1.65–5.5 V, tPD = 4.2 ns @ 3.3 V | Includes hysteresis for noisy environments but no tri-state or IOFF; not automotive-qualified | Select for EMI-prone industrial sensors where noise rejection outweighs power-down needs. |
Compared with MC74VHC125DTG and SN74LVC3G17DCUR, the NL37WZ16USG-Q uniquely combines AEC-Q100 qualification, IOFF-enabled partial power-down, and sub-2.5 ns propagation delay - making it the only option qualified for automotive power-gating architectures requiring zero-leakage isolation.

FAQ
What is the maximum operating temperature range for the NL37WZ16USG-Q?
The NL37WZ16USG-Q is rated for operation from −55 °C to +125 °C ambient temperature. This full Grade 1 AEC-Q100 range is validated per JESD22-A108 and supports deployment in under-hood automotive locations such as transmission control modules and engine management systems where thermal extremes occur.
Does the NL37WZ16USG-Q support true tri-state operation on each output?
Yes, the NL37WZ16USG-Q supports independent tri-state control per output: Y1 follows A1, Y2 follows A2, and Y3 follows A3. When an input is driven to a logic high or low, the corresponding output drives actively; when the input is left floating or externally gated to high-impedance, the output enters high-Z state - confirmed in the Function Table and AC Characteristics section of the datasheet.
Is the NL37WZ16USG-Q pin-compatible with the standard NL37WZ16USG?
Yes, the NL37WZ16USG-Q shares identical pinout, electrical specifications, and US8 package dimensions with NL37WZ16USG. The "−Q" suffix denotes AEC-Q100 qualification, PPAP capability, and automotive-specific process controls - no physical or functional changes affect pin compatibility or PCB layout.
What is the input voltage tolerance of the NL37WZ16USG-Q when VCC = 1.8 V?
When VCC = 1.8 V, the NL37WZ16USG-Q inputs remain tolerant up to 5.5 V per the Absolute Maximum Ratings table. This overvoltage capability is process-inherent and does not depend on VCC level - enabling safe interfacing with 5 V buses while powered from 1.8 V rails without external protection.
How does the IOFF feature function in the NL37WZ16USG-Q during system sleep mode?
During system sleep mode when VCC = 0 V, the NL37WZ16USG-Q activates its IOFF circuitry, limiting output leakage current to ≤10 µA even if inputs or outputs are biased to 5.5 V. This prevents unintended current flow into unpowered subsystems - a requirement verified in AEC-Q100 stress testing and critical for meeting automotive quiescent current targets.
