Product details
Overview
NLV17SZ126DFT2G from onsemi is a single non-inverting 3-state buffer IC designed for voltage-level translation and bus isolation in space-constrained systems. It operates from 1.65 V to 5.5 V, delivers 2.3 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 low-power portable logic interfaces and mixed-voltage I/O bridging.
For engineers reviewing the NLV17SZ126DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include its SC-88A package footprint, tri-state enable timing (tPZH/tPHZ ≤ 5.8 ns), overvoltage-tolerant inputs/outputs up to 5.5 V, and AEC-Q100 qualification for automotive-grade designs.
Technical Context
The NLV17SZ126DFT2G implements a single-channel non-inverting buffer with active-high 3-state enable (OE), enabling bidirectional bus control without signal inversion. Its IOFF circuitry blocks current flow when VCC = 0 V, preventing back-driving of powered subsystems during partial power-down sequences.
It supports mixed-voltage operation across 1.65–5.5 V supply rails, with input thresholds scaled to VCC (VIH = 0.70×VCC above 2.3 V) and output drive capability maintained across the full range - including 24 mA sink/source at 3.0 V and sub-5 ns propagation delay at 5 V with 15 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability between 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 fast signal pass-through for high-speed digital control paths |
| IOFF Leakage | ≤10 µA at VCC = 0 V - guarantees safe isolation during system sleep or hot-swap events |
| Output Drive | ±24 mA at VCC = 3.0 V - drives multiple standard CMOS loads without external buffering |
| Input Tolerance | Inputs/outputs rated to 5.5 V regardless of VCC - allows interfacing with higher-voltage peripherals |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets industrial robustness requirements for board-level handling |
| Operating Temp | −55 °C to +125 °C - supports extended-temperature applications including under-hood automotive |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (A) | Buffer Input | Accepts logic-level signals; tolerant to 5.5 V regardless of VCC setting |
| 3 (GND) | Ground Reference | Primary return path for all internal logic and output current; must be low-impedance |
| 4 (Y) | Buffer Output | Non-inverted replica of A when OE = high; high-Z when OE = low; 5.5 V tolerant |
| 5 (VCC) | Supply Voltage | Power rail for internal logic and output stage; supports 1.65–5.5 V operation |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65 V to 5.5 V operation - eliminates need for level shifters in multi-rail systems |
| Fast Propagation Delay | 2.0 ns typical at 5 V - preserves timing margins in high-frequency control loops |
| IOFF Partial Power-Down | Blocks current flow when VCC = 0 V - prevents back-powering and data corruption during power sequencing |
| Overvoltage-Tolerant I/O | 5.5 V tolerance on A, Y, and OE pins - enables direct connection to 5 V buses even at 1.8 V VCC |
| AEC-Q100 Qualified | Qualified per AEC-Q100 Rev G Grade 1 (−40 °C to +125 °C) - certified for automotive infotainment and body electronics |

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 |
|---|---|---|---|
| SN74LVC1G126DBVR | Same SC-70-5 (SC-88A) package; 1.65–5.5 V; 3.7 ns tPD at 3.3 V; no AEC-Q100 rating | Targeted at commercial/industrial use only; lacks automotive qualification and extended temperature support | Select when AEC-Q100 compliance is not required and lower cost is prioritized over automotive reliability assurance |
| 74LVC1G126GW,125 | SOT-353 (SC-88A) package; 1.65–5.5 V; 3.2 ns tPD at 3.3 V; IOFF supported; RoHS compliant | No AEC-Q100 qualification; specified only to +85 °C ambient; slightly slower timing | Choose for consumer or industrial applications where −40 °C to +125 °C operation is unnecessary |
Compared with SN74LVC1G126DBVR and 74LVC1G126GW,125, the NLV17SZ126DFT2G offers tighter propagation delay (2.0 ns vs ≥3.2 ns), guaranteed operation to +125 °C, and formal AEC-Q100 Grade 1 qualification - making it the only option suitable for automotive under-hood and safety-critical embedded control.

FAQ
What is the maximum operating temperature range for the NLV17SZ126DFT2G?
The NLV17SZ126DFT2G is rated for operation from −55 °C to +125 °C, meeting AEC-Q100 Grade 1 requirements. This extended range supports deployment in under-hood automotive environments and industrial control cabinets exposed to wide ambient fluctuations. The NLV17SZ126DFT2G maintains full electrical performance across this entire span without derating.
Does the NLV17SZ126DFT2G support partial power-down functionality?
Yes, the NLV17SZ126DFT2G includes IOFF circuitry that actively disables input and output paths when VCC = 0 V, limiting leakage current to ≤10 µA. This feature prevents back-driving of powered subsystems during power sequencing or hot-swap events - a critical capability confirmed in the datasheet's DC Electrical Characteristics table for the NLV17SZ126DFT2G.
What package type is used for the NLV17SZ126DFT2G?
The NLV17SZ126DFT2G uses the SC-88A package (also known as SC-70-5 or SOT-353), a 5-pin surface-mount outline measuring 2.00 mm × 1.25 mm × 0.95 mm with 0.65 mm lead pitch. This compact footprint is explicitly listed in the Device Ordering Information section of the NLV17SZ126DFT2G datasheet under "Packages".
Can the NLV17SZ126DFT2G interface between 1.8 V and 5 V logic domains?
Yes, the NLV17SZ126DFT2G supports seamless 1.8 V to 5 V interfacing: its VCC can be set to 1.8 V while its inputs (A, OE) and output (Y) tolerate up to 5.5 V. This overvoltage tolerance - verified in the Maximum Ratings and DC Electrical Characteristics tables - allows direct connection to 5 V buses without external clamping or level-shifting components for the NLV17SZ126DFT2G.
Is the NLV17SZ126DFT2G pin-compatible with other SC-88A logic buffers?
No - the NLV17SZ126DFT2G has a unique pinout (OE/A/GND/Y/VCC) that differs from industry-standard SC-88A buffers like the SN74LVC1G125 (which places GND at Pin 3 but VCC at Pin 5). Pin compatibility cannot be assumed; the NLV17SZ126DFT2G pin assignment is defined in Figure 2 and the PIN ASSIGNMENT table of its official datasheet.
