Product details
Overview
NLV37WZ16USG from onsemi is a high-performance triple non-inverting buffer IC operating from 1.65 V to 5.5 V, delivering 2.4 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 - used in level-shifting and signal fanout within automotive body control modules.
For engineers reviewing the NLV37WZ16USG datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, US8 package layout, AEC-Q100 qualification context, and validated alternative options for automotive-grade logic interfacing.
Technical Context
The NLV37WZ16USG implements three independent CMOS buffer stages with rail-to-rail input voltage tolerance (−0.5 V to VCC + 0.5 V) and IOFF partial power-down protection. Each buffer supports tri-state operation via individual inputs and maintains defined output states during VCC = 0 V conditions.
It operates across −55 °C to +125 °C with guaranteed timing performance at 1.65–5.5 V supply, including 3.6 ns max tPLH/tPHL at 3.3 V/50 pF load and 4.2 ns max under same conditions at 5.0 V - meeting AEC-Q100 Grade 1 requirements for automotive electronics.
Key Specifications

|---|---|
Use Scenario: Signal buffering between 3.3 V microcontroller GPIOs and 5 V solenoid drivers in door module ECUs. IC Role / Device Role / Timing Role: Triple buffer isolates MCU pins from inductive kickback, provides level-shifted fanout, and ensures deterministic 2.4 ns propagation for timing-critical window lift commands. Use Value: Eliminates need for discrete level shifters and reduces BOM count by three components while maintaining AEC-Q100 compliance. | Use Scenario: Driving multiple optocoupler inputs from a single FPGA bank in modular I/O terminal blocks. IC Role / Device Role / Timing Role: Fanout buffer distributes clock or enable signals across eight isolated channels with matched skew <0.5 ns between Y1/Y2/Y3 outputs. Use Value: Enables deterministic signal distribution without added trace-length matching; ±24 mA drive sustains 10 mA per optocoupler LED at 3.3 V. |
| Automotive Infotainment Display Interface | Medical Diagnostic Equipment Data Bus |
Use Scenario: Level translation between 1.8 V display controller and 5 V backlight PWM driver in head-unit LCD assemblies. IC Role / Device Role / Timing Role: Non-inverting buffer translates logic levels bidirectionally (due to overvoltage tolerance) while preserving edge integrity for 100 kHz PWM dimming signals. Use Value: Supports seamless integration without external voltage translators; 5.5 V I/O tolerance accommodates transient overshoot on backlight lines. | Use Scenario: Isolating and buffering serial communication lines (UART TX/RX/CTS) between low-power ARM core and legacy RS-232 transceivers in portable ultrasound devices. IC Role / Device Role / Timing Role: Signal conditioner providing ESD-hardened, low-skew buffering with guaranteed timing at 125 °C junction temperature during extended imaging sessions. Use Value: Maintains data integrity under thermal stress; 2000 V HBM rating exceeds IEC 61000-4-2 Level 4 requirements for handheld medical equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC126DTG | Quad buffer (4 channels), 3.5 ns tPD at 5 V, 2.0 V min VCC, no IOFF | Higher channel count but lacks partial power-down; not AEC-Q100 qualified | Select when needing four buffers and operating strictly above 2.0 V; verify thermal margin without IOFF in power-gated systems |
| SN74LVC1G17DBVR | Single Schmitt-trigger buffer, 5 ns tPD at 3.3 V, 1.65–5.5 V VCC, no tri-state | Single-channel only; no output enable or tri-state; different logic behavior (hysteresis) | Use only for noise-immune single-signal conditioning; not a functional substitute for triple non-inverting buffering with tri-state |
Compared with MC74VHC126DTG and SN74LVC1G17DBVR, the NLV37WZ16USG uniquely combines triple buffering, IOFF-enabled power sequencing, AEC-Q100 qualification, and 2.4 ns speed - making it the only drop-in solution for automotive signal fanout requiring simultaneous low-VCC operation and fail-safe shutdown behavior.

FAQ
What is the maximum operating temperature for NLV37WZ16USG?
The NLV37WZ16USG is rated for operation from −55 °C to +125 °C junction temperature and is AEC-Q100 Grade 1 qualified. Its thermal resistance (θJA) is 250 °C/W in the US8 package, so proper PCB copper area and airflow must be maintained to avoid exceeding TJ(max) = +150 °C under full load. Derating curves in the official datasheet confirm stable operation at +125 °C ambient with appropriate layout.
Does NLV37WZ16USG support tri-state operation?
Yes, NLV37WZ16USG supports tri-state operation on all three outputs (Y1, Y2, Y3). Each output enters high-impedance mode when its corresponding input (A1, A2, A3) is held at a valid logic low or high level - no dedicated OE pin is required. The device uses standard CMOS buffer architecture where output state follows input state, and tri-state is achieved by controlling input logic levels in conjunction with system-level enable sequencing.
Is NLV37WZ16USG pin-compatible with NL37WZ16USG?
Yes, NLV37WZ16USG and NL37WZ16USG share identical US8 pinout, electrical specifications, and functional behavior. The "V" prefix denotes enhanced automotive qualification (including stricter screening and PPAP support), while both parts use the same die and packaging. No PCB changes are required when upgrading from NL37WZ16USG to NLV37WZ16USG in AEC-Q100-compliant designs.
What is the input voltage range relative to VCC for NLV37WZ16USG?
The NLV37WZ16USG features overvoltage-tolerant inputs that accept DC voltages from −0.5 V to +5.5 V regardless of VCC value (1.65–5.5 V). This means inputs remain functional and non-damaging even when driven by 5 V signals while VCC = 1.8 V - eliminating external level-shifting circuitry in mixed-supply systems. VIH/VIL thresholds scale with VCC per datasheet tables.
Can NLV37WZ16USG drive a 50 Ω transmission line directly?
Yes, NLV37WZ16USG can drive a 50 Ω transmission line directly when VCC ≥ 3.0 V. At VCC = 3.0 V, it sources/sinks ±24 mA, enabling a clean 3.0 V swing into 50 Ω (60 mA peak current required for full swing). Measured tPLH/tPHL remains within spec (≤3.6 ns at 3.3 V/50 pF), and output impedance matches typical CMOS drivers (~10–15 Ω), allowing controlled-edge signaling without external series termination in short-line applications.
