Product details
Overview
NL17SG126DFT2G from onsemi is a single-channel, 3-state bus buffer IC designed for low-voltage logic level translation and signal isolation in space-constrained digital systems. It operates across 0.9 V to 3.6 V supply, delivers 2.4 ns typical propagation delay at 3.0 V/15 pF, supports ±20 mA output drive, and features 4.6 V overvoltage-tolerant inputs - enabling robust interfacing between mixed-supply domains in portable and industrial control applications.
For engineers reviewing the NL17SG126DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include its ultra-small SC-88A (SOT-353) 5-pin package, rail-to-rail input tolerance, sub-3 ns timing performance at 3.0 V, and guaranteed operation down to −55°C - critical for battery-powered IoT nodes, sensor hubs, and automotive body electronics.
Technical Context
The NL17SG126DFT2G implements a single non-inverting buffer with active-low 3-state enable (OE), supporting bidirectional bus isolation in point-to-point or stubbed topologies. Its CMOS input structure enables 4.6 V overvoltage tolerance independent of VCC, while the output stage provides symmetrical sourcing/sinking capability up to ±20 mA under all valid supply conditions.
Timing behavior is characterized across five VCC ranges (0.9 V to 3.6 V) with load-dependent propagation delays (e.g., 2.4 ns typ @ 3.0 V/15 pF) and disable times as low as 5.4 ns (typ). Input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC), ensuring noise margin preservation across voltage scaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without level shifters. |
| tPLH/tPHL | 2.4 ns typical @ VCC = 3.0 V, CL = 15 pF - supports >300 MHz data rates in short-trace applications. |
| IOUT | ±20 mA - drives standard 50 Ω transmission lines or multiple 10 kΩ pull-up loads without external buffering. |
| VIN Max | 4.6 V - allows safe connection to higher-voltage peripherals (e.g., 5 V sensors) while powered from 1.8 V or 2.5 V rails. |
| ICC (Quiescent) | 1.0 µA max @ VCC = 3.6 V - minimizes standby power in always-on subsystems like wake-on-event controllers. |
| Operating Temp | −55°C to +125°C - qualified for under-hood automotive, industrial motor drives, and outdoor infrastructure equipment. |
| Package | SC-88A (SOT-353), 5-pin - 1.25 mm × 1.65 mm footprint ideal for high-density PCB layouts in wearables and compact modules. |
Pinout & Package
SC-88A (SOT-353) package: 1.25 mm × 1.65 mm × 0.95 mm body, 0.65 mm pitch, Pb-free and halide-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low Output Enable | Drives output Y to high-impedance state when logic high; enables bus sharing and hot-swap isolation. |
| 2 (IN A) | Buffer Input | Accepts 0.9–4.6 V logic signals; threshold scales with VCC for consistent noise immunity across supply voltages. |
| 3 (GND) | Ground Reference | Primary return path for I/O and supply currents; requires low-inductance connection to minimize ground bounce. |
| 4 (VCC) | Positive Supply | Supplies core logic and output drivers; bypass capacitor (0.1 µF) required within 2 mm for stable high-speed operation. |
| 5 (OUT Y) | Buffered Output | Non-inverted replica of IN A when OE is low; sinks or sources up to ±20 mA with <0.4 V VOL / >2.75 V VOH @ 3.3 V. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA max); no OVT inputs (max VIN = VCC + 0.5 V). | Suitable for 5 V systems but requires external clamping for 4.6 V inputs; less optimal for sub-1.8 V operation. | Select when interfacing native 5 V logic and board space permits larger SOT-23-5 package. |
| 74LVC1G17GW,125 | Same SC-88A package; Schmitt-trigger inputs (not OVT); VIH/VIL fixed thresholds, not VCC-scaled. | Better noise immunity in high-EMI environments but incompatible with mixed-voltage signaling where input exceeds VCC. | Prefer for noisy industrial sensor lines where hysteresis improves reliability, but avoid when interfacing 4.6 V sources. |
Compared with SN74LVC1G125DBVR and 74LVC1G17GW,125, the NL17SG126DFT2G uniquely combines 4.6 V overvoltage tolerance, sub-1 µA quiescent current, and guaranteed −55°C operation - making it the only option qualified for ultra-low-power, mixed-voltage, wide-temperature embedded interfaces without external protection components.

FAQ
What is the maximum input voltage rating for NL17SG126DFT2G?
The NL17SG126DFT2G supports DC input voltages up to 4.6 V on all input pins (IN A and OE), regardless of VCC level. This overvoltage tolerance is specified in the Absolute Maximum Ratings table and verified per JEDEC standards - enabling direct connection to 5 V peripherals without external clamping diodes. The NL17SG126DFT2G maintains this rating across its full operating temperature range (−55°C to +125°C).
Does NL17SG126DFT2G support operation below 1.0 V?
Yes, the NL17SG126DFT2G is fully specified down to 0.9 V VCC, with AC and DC parameters validated at that minimum supply. At 0.9 V, propagation delay increases to 11.3 ns (typ) with 10 pF load, and output drive capability remains functional at ±20 mA. This makes the NL17SG126DFT2G suitable for ultra-low-power applications powered by single-cell LiFePO4 or NiMH batteries.
What is the thermal performance of NL17SG126DFT2G in SC-88A package?
The NL17SG126DFT2G in SC-88A (SOT-353) package has a junction-to-ambient thermal resistance (RθJA) of 270°C/W on a standard 2-layer FR-4 board with minimal copper. Its maximum junction temperature is +150°C, and it is rated for continuous operation from −55°C to +125°C ambient. Derating is not required below +100°C ambient when dissipating ≤1.5 mW - typical for most logic-level buffering tasks.
Can NL17SG126DFT2G be used as a level shifter between 1.8 V and 3.3 V domains?
Yes, the NL17SG126DFT2G functions as a unidirectional level shifter: its 4.6 V OVT inputs accept 3.3 V logic while powered from 1.8 V, and its output swings rail-to-rail (0 V to 1.8 V) compatible with downstream 1.8 V receivers. However, it does not translate in the reverse direction (1.8 V out → 3.3 V in) without external pull-ups, as the output cannot exceed VCC. The NL17SG126DFT2G is optimized for source-domain voltage translation only.
Is NL17SG126DFT2G pin-compatible with other MiniGate™ buffers?
No - the NL17SG126DFT2G uses a dedicated 5-pin SC-88A pinout (OE, IN A, GND, VCC, OUT Y) that differs from other MiniGate™ variants like the dual-channel NL17SG125 or inverting NL17SG04. While all share the same package outline, pin assignments are function-specific and not interchangeable. Board layout must match the exact NL17SG126DFT2G pin mapping shown in Figure 2 of the datasheet.
