Product details
Overview
NLV27WZ126USG from onsemi is a dual noninverting buffer with 3-state outputs, designed for level translation and bus isolation in low-voltage digital 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 at 3.0 V, and features IOFF partial power-down protection - used in automotive infotainment data routing and industrial I/O expansion.
For engineers reviewing the NLV27WZ126USG datasheet, pinout, applications, or equivalent options, key selection criteria include 3-state enable timing (tPZH/tPHZ), overvoltage-tolerant inputs up to 5.5 V, US8 package footprint compatibility, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The NLV27WZ126USG implements two independent noninverting buffers, each with dedicated output-enable (OE1/OE2) control and tri-state capability. Its IOFF circuitry prevents current backflow when VCC = 0 V, enabling live insertion and hot-swap operation in multi-rail systems.
It supports mixed-voltage interfacing: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), and outputs drive CMOS/TTL loads with rail-to-rail swing. Propagation delay varies with supply voltage (2.0 ns typ at 5 V, 6.0 ns max at 1.65–1.95 V) and load capacitance (15 pF or 50 pF).
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 |
| tPLH / tPHL | 2.0 ns (typ) at VCC = 5 V, CL = 15 pF - ensures sub-5 ns timing margin for 100+ MHz bus clocking |
| IOFF Leakage | <10 µA at VCC = 0 V - guarantees safe partial power-down without signal contention |
| Drive Strength | ±24 mA at VCC = 3.0 V - supports driving 10+ standard CMOS loads or 2x 50 Ω transmission lines |
| Input Tolerance | −0.5 V to +6.5 V - allows direct connection to 5 V signals even when powered from 1.8 V |
| ESD Rating | 2000 V HBM - meets industrial I/O port robustness requirements per IEC 61000-4-2 Level 2 |
Pinout & Package
Package: US8 (Case 493), 8-pin ultra-small surface-mount, 2.1 mm × 2.0 mm × 0.55 mm body, lead pitch 0.5 mm, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (A1) | Input 1 | Noninverting input for first buffer channel |
| 3 (Y2) | Output 2 | Inverted-output naming reflects logic symbol convention; actual function is noninverting |
| 4 (GND) | Ground | Reference return path for all signals and supply current |
| 5 (A2) | Input 2 | Noninverting input for second buffer channel |
| 6 (Y1) | Output 1 | Noninverting output corresponding to A1 and OE1 |
| 7 (OE2) | Output Enable 2 | Active-high control for Y2; independent of OE1 |
| 8 (VCC) | Supply Voltage | Single positive supply for both channels; no separate VCC/GND pairs required |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-Tolerant Inputs | Accepts 0–5.5 V inputs regardless of VCC (1.65–5.5 V), eliminating external level shifters in mixed-supply buses |
| IOFF Partial Power-Down | Blocks current flow between powered and unpowered sections during hot-swap or sleep mode, preventing system latch-up |
| Low Capacitance I/O | 2.5 pF input/output capacitance minimizes loading on high-speed traces and preserves signal integrity up to 200 MHz |
| AEC-Q100 Qualified | Qualified to Grade 1 (−40 °C to +125 °C) with PPAP documentation support - suitable for under-hood automotive modules |
Applications
| Automotive Body Control Module | Industrial PLC Digital I/O Expansion |
|---|---|
Use Scenario: Isolating microcontroller GPIOs from noisy 12 V vehicle bus signals while maintaining bidirectional communication via shared data lines. IC Role / Device Role / Timing Role: Dual buffer provides independent 3-state control per channel to prevent bus contention during firmware updates or fault recovery. Use Value: IOFF protection eliminates need for external blocking diodes; overvoltage tolerance avoids level-shifter ICs, reducing BOM count by 2 components per channel. | Use Scenario: Expanding discrete input/output capacity on a modular PLC base unit using standardized 3.3 V FPGA I/O banks connected to 24 V field sensors/actuators. IC Role / Device Role / Timing Role: Acts as voltage-translating bus driver with fast enable/disable (tPZH = 2.1 ns typ) to synchronize with FPGA clock domain transitions. Use Value: 24 mA drive strength supports direct connection to optocoupler inputs without external transistors; US8 footprint fits dense I/O carrier layouts. |
| Medical Diagnostic Equipment Backplane | Consumer Audio DSP Interface |
Use Scenario: Buffering configuration registers and status flags between low-power ARM Cortex-M4 host and high-noise analog front-end ASICs in portable ultrasound units. IC Role / Device Role / Timing Role: Provides noise-immune signal isolation with sub-5 ns propagation delay to maintain real-time control loop timing budgets. Use Value: 2.5 pF I/O capacitance reduces jitter on critical timing lines; AEC-Q100 qualification ensures long-term reliability in Class II medical devices. | Use Scenario: Interfacing a 1.8 V audio codec's serial control interface (I²C/SPI) with a 3.3 V DSP that lacks native 1.8 V I/O support. IC Role / Device Role / Timing Role: Functions as bidirectional voltage translator with independent OE control per line to avoid bus lockup during power sequencing. Use Value: Input overvoltage tolerance allows safe 3.3 V pull-ups on 1.8 V data lines; 2.4 ns delay preserves setup/hold margins for 20 MHz SPI clocks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126DBVR | Same US8 package, but rated only to 3.6 V VCC max; no IOFF; lower ESD (1500 V HBM) | Not qualified to AEC-Q100; unsuitable for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification and partial power-down requirement |
| 74LVC2G126GM,132 | US8 package, 1.65–5.5 V range, IOFF supported, but only 12 mA drive at 3.3 V and higher propagation delay (3.7 ns typ @ 3.3 V) | Lacks AEC-Q100 qualification; intended for commercial industrial use only | Select when lower drive strength suffices and automotive compliance is not required |
Compared with SN74LVC2G126DBVR and 74LVC2G126GM,132, the NLV27WZ126USG uniquely combines AEC-Q100 Grade 1 qualification, full 5.5 V overvoltage tolerance, and ±24 mA drive in the US8 footprint - making it the only option qualified for safety-critical automotive signal routing where hot-swap resilience and mixed-voltage robustness are mandatory.

FAQ
What is the operating temperature range for NLV27WZ126USG?
The NLV27WZ126USG is specified for −55 °C to +125 °C operation, meeting AEC-Q100 Grade 1 requirements. This extended range supports deployment in under-hood automotive environments and industrial control cabinets exposed to thermal cycling. The device maintains full functionality across this range, including guaranteed 3-state behavior and IOFF leakage below 10 µA at extremes.
Does NLV27WZ126USG support partial power-down (IOFF) functionality?
Yes, NLV27WZ126USG includes IOFF circuitry that disables current paths between inputs and outputs when VCC = 0 V. This feature prevents back-driving and signal contention during hot-swap or system sleep modes. Measured IOFF leakage is ≤10 µA at 5.5 V input and 125 °C, ensuring safe operation in multi-rail systems where subsystems power up/down asynchronously.
What is the maximum output drive capability of NLV27WZ126USG at 3.3 V supply?
At VCC = 3.3 V, NLV27WZ126USG delivers ±24 mA output drive per channel into resistive loads. This is confirmed in the DC Electrical Characteristics table under VOH/VOL conditions with IOUT = ±24 mA. The drive strength supports direct interfacing with multiple CMOS inputs or termination-matched transmission lines without external buffers.
Is NLV27WZ126USG pin-compatible with standard 74LVC2G126 variants?
No, NLV27WZ126USG is not pin-compatible with generic 74LVC2G126 parts. While both use US8 packages, the pin assignment differs: NLV27WZ126USG places OE1 on Pin 1 and GND on Pin 4, whereas 74LVC2G126 typically assigns GND to Pin 1 and OE1 to Pin 5. Always verify pinout against Figure 2 in the NLV27WZ126USG datasheet before PCB layout.
What packaging and compliance certifications apply to NLV27WZ126USG?
NLV27WZ126USG is supplied in a Pb-free, halogen-free, RoHS-compliant US8 package (Case 493). It carries AEC-Q100 qualification for automotive applications and is PPAP-capable. The "G" suffix denotes Pb-free construction, and the marking includes date code and assembly location per onsemi's standard scheme - verified on page 7 of the official datasheet.
