Product details
Overview
NLV68SZ126MN2TWG from onsemi is a 6-channel non-inverting 3-state buffer IC designed for level-shifting and bus isolation in automotive and industrial control systems, operating from 1.65 V to 5.5 V, delivering 3.4 ns propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and over-voltage tolerant inputs/outputs up to 5.5 V.
For engineers reviewing the NLV68SZ126MN2TWG datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (QFN20, 2.5 mm × 3.5 mm), validated channel-level enable control logic, IOFF partial power-down support, AEC-Q100 qualification status, and real-world timing behavior under 15 pF load conditions.
Technical Context
The NLV68SZ126MN2TWG implements six independent non-inverting buffer channels, each with dedicated active-high output-enable (OE) inputs enabling per-channel tri-state control. Its architecture supports mixed-voltage system interfacing via over-voltage tolerant I/Os that operate safely up to 5.5 V regardless of VCC level.
It features IOFF circuitry that disables current flow between powered and unpowered domains during partial power-down, preventing back-driving and latch-up. Propagation delay varies with supply voltage and load: 3.4 ns (typ) at 5 V/15 pF, scaling to 13.0 ns (typ) at 1.65–1.95 V/15 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 without level shifters. |
| tPD (Typ) | 3.4 ns at 5 V, RL = 1 MΩ, CL = 15 pF - Supports high-speed data routing in automotive CAN/LIN interface buffers and sensor signal conditioning paths. |
| I/O Voltage Tolerance | Up to 5.5 V - Allows safe connection to legacy 5 V buses while powered from lower VCC, eliminating external clamping diodes. |
| IOFF Support | Active when VCC = 0 V - Prevents current leakage and back-powering in hot-swap or modular subsystems during power sequencing. |
| Drive Strength | ±24 mA at 3.0 V - Sufficient to drive multiple CMOS loads or short PCB traces without signal degradation. |
| Operating Temp | −55 °C to +125 °C - Qualified for under-hood automotive applications and industrial motor control environments. |
| AEC-Q100 Grade | Grade 1 - Certified for automotive use with full PPAP documentation and controlled manufacturing site requirements (NLV prefix). |

Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operation | 1.65 V to 5.5 V - Eliminates need for separate voltage translators in multi-rail automotive ECUs. |
| Per-channel OE control | Six independent OE pins - Enables fine-grained bus arbitration and selective channel isolation in distributed sensor networks. |
| IOFF partial power-down | Zero current flow when VCC = 0 V - Critical for fail-safe behavior in battery-disconnected modules or sleep-mode subsystems. |
| Over-voltage tolerant I/O | 5.5 V max on all pins - Simplifies design in mixed-voltage clusters (e.g., 3.3 V MCU interfacing to 5 V analog front-ends). |
| AEC-Q100 qualified | Grade 1, NLV prefix - Guarantees automotive-grade reliability, traceable lot control, and PPAP-ready documentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC126DTG | 4-channel, SOIC-14, no IOFF, −40 °C to +85 °C industrial grade | Lacks AEC-Q100 qualification and partial power-down; limited to non-automotive environments | Select only for cost-sensitive industrial prototypes where extended temperature and automotive compliance are not required. |
| SN74LVC126APWR | 4-channel, TSSOP-14, 1.65–3.6 V VCC, no over-voltage tolerance beyond VCC | Cannot interface directly with 5 V buses; requires external protection for mixed-voltage use cases | Choose when system operates strictly within 3.3 V domain and board space permits larger TSSOP footprint. |

FAQ
What is the maximum operating temperature for NLV68SZ126MN2TWG?
The NLV68SZ126MN2TWG is rated for continuous operation from −55 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all six channels and applies under full load conditions with proper PCB thermal design, including connection of the exposed thermal pad to a solid ground plane. The NLV68SZ126MN2TWG junction temperature must not exceed +150 °C under bias.
Does NLV68SZ126MN2TWG support partial power-down mode?
Yes, the NLV68SZ126MN2TWG supports partial power-down via its IOFF feature: when VCC = 0 V, all I/O terminals enter high-impedance state with leakage current limited to ≤10 µA (max), preventing back-current flow between powered and unpowered subsystems. This behavior is explicitly characterized in the datasheet's DC Electrical Characteristics table under IOFF parameter and applies to all 20 pins of the NLV68SZ126MN2TWG.
What package type does NLV68SZ126MN2TWG use?
The NLV68SZ126MN2TWG uses a QFN20 package (Case 485CB) measuring 2.5 mm × 3.5 mm with 0.4 mm pitch and an exposed thermal pad. Pin 1 is marked by a dot; the top-through view matches Figure 3 in the official datasheet. This package is distinct from the TSSOP-20 variant (NLV68SZ126DTR2G) and is optimized for space-constrained automotive modules requiring superior thermal performance.
Is NLV68SZ126MN2TWG compatible with 5 V logic systems?
Yes, the NLV68SZ126MN2TWG supports 5 V logic compatibility through two key features: inputs and outputs are over-voltage tolerant up to 5.5 V regardless of VCC setting, and it operates with VCC as high as 5.5 V. When powered at 5.0 V, the NLV68SZ126MN2TWG delivers 3.4 ns typical propagation delay and ±24 mA drive strength-fully meeting standard 5 V TTL/CMOS interface requirements without external level shifters.
What is the function of the OE pins on NLV68SZ126MN2TWG?
The NLV68SZ126MN2TWG has six independent active-high output-enable (OE) pins-OE1 through OE6-each controlling one of the six buffer channels. When an OE pin is low, the corresponding Yn output enters high-impedance (tri-state) mode; when high, the Yn output follows the An input non-invertingly. This per-channel control enables dynamic bus segmentation, reducing contention in multi-master systems and supporting flexible signal routing in automotive domain controllers.
