Product details
Overview
NL17SZ126P5T5G-L22088 from onsemi is a single non-inverting 3-state buffer IC designed for level translation and bus isolation in low-voltage digital 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, tolerates input/output voltages up to 5.5 V independent of VCC, and features IOFF partial power-down protection. It is used in portable logic interfacing, I²C bus buffering, and mixed-voltage signal routing.
For engineers reviewing the NL17SZ126P5T5G-L22088 datasheet, pinout, applications, or equivalent options, key selection criteria include VCC operating range compatibility, tri-state enable timing (tPZH/tPHZ), output drive strength at target supply voltage, overvoltage tolerance for mixed-rail environments, and SOT-953 footprint constraints in space-constrained PCB layouts.
Technical Context
The NL17SZ126P5T5G-L22088 implements a single-channel non-inverting buffer with active-high output enable (OE) controlling high-impedance state. Its CMOS design enables rail-to-rail input switching thresholds (VIH/VIL scaling with VCC) and supports hot-swap capability via IOFF, which disables leakage paths when VCC = 0 V. The device maintains defined logic states across −55 °C to +125 °C.
It exhibits low capacitive loading (CIN/COUT = 2.5 pF typ) and low dynamic power consumption (CPD = 11 pF at 5.5 V), making it suitable for high-speed, low-noise signal conditioning in battery-powered and thermally constrained applications. Propagation delay varies with VCC and load: 2.0 ns typ (4.5–5.5 V, RL = 1 MΩ, CL = 15 pF) to 6.0 ns max (1.65–1.95 V).
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 without level shifters. |
| tPLH / tPHL | 2.0 ns typ at 5 V - Supports >200 MHz data rates in short-trace, low-capacitance interconnects. |
| IOH / IOL | ±24 mA at 3.0 V - Drives multiple standard CMOS inputs or small capacitive loads without external buffers. |
| Input/Output Overvoltage | Up to 5.5 V - Allows safe interface with higher-voltage peripherals even when VCC is 1.65 V. |
| IOFF Leakage | 1.0 µA max at 0 V VCC - Prevents back-powering and signal contention during partial system power-down. |
| Operating Temp | −55 °C to +125 °C - Qualified for extended industrial and automotive under-hood environments. |
| Package | SOT-953 (1.00 × 0.80 × 0.37 mm) - Ultra-compact 5-pin footprint for ultra-dense portable PCBs. |
Pinout & Package
SOT-953 is a 5-pin ultra-thin leadless package (1.00 mm × 0.80 mm × 0.37 mm, 0.35 mm pitch) with exposed pad for thermal enhancement. Pin 1 orientation is rotated 180° clockwise per onsemi ordering information.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A | Data input; accepts 0–5.5 V signals regardless of VCC value. |
| 2 | GND | Ground reference for all internal circuitry and output return path. |
| 3 | OE | Active-high output enable; drives Y high-impedance when low. |
| 4 | Y | Non-inverting buffered output; tri-statable, overvoltage-tolerant. |
| 5 | VCC | Positive supply; powers internal logic and defines VIH/VIL thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operation | 1.65–5.5 V enables single-buffer reuse across multiple voltage rails in multi-supply systems. |
| Overvoltage-tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC, eliminating need for external clamping diodes. |
| IOFF partial power-down | Blocks current flow between powered and unpowered sections during sleep mode, preventing system-level latch-up. |
| Low propagation delay | 2.0 ns typ at 5 V ensures minimal timing skew in clock distribution or data path buffering. |
| Ultra-small SOT-953 | 1.00 × 0.80 mm footprint saves >60% board area vs. SC-74A-5, critical for wearables and hearing aids. |
Applications

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 |
|---|---|---|---|

FAQ
What is the pin 1 marking and orientation for NL17SZ126P5T5G-L22088?
The NL17SZ126P5T5G-L22088 uses the SOT-953 package with pin 1 oriented rotated 180° clockwise relative to standard orientation, as confirmed in the onsemi ordering information table. Marking consists of a single letter code (R) followed by a date code; the "G" suffix indicates Pb-free and RoHS compliance. Physical identification requires magnification due to 0.35 mm pitch.
Does NL17SZ126P5T5G-L22088 support true 5 V tolerant inputs when operated at 1.8 V VCC?
Yes. The NL17SZ126P5T5G-L22088 guarantees input and output overvoltage tolerance up to 5.5 V independent of VCC level, including at 1.65 V minimum. This is explicitly specified in the Absolute Maximum Ratings table (VIN, VOUT = −0.5 to +6.5 V) and confirmed in the Features list - enabling direct connection to 5 V buses without level shifters or clamping diodes.
What is the maximum output drive capability of NL17SZ126P5T5G-L22088 at 3.3 V VCC?
At VCC = 3.3 V, the NL17SZ126P5T5G-L22088 sources and sinks up to ±24 mA, as specified in the DC Electrical Characteristics table under VOH/VOL conditions. This drive strength supports fan-out to ≥10 standard CMOS loads (assuming 2.4 mA per load) or direct driving of small LEDs and logic inputs in portable systems.
Is NL17SZ126P5T5G-L22088 qualified for automotive applications?
The base NL17SZ126P5T5G is not automotive-qualified; however, the automotive-grade variant NL17SZ126P5T5G-Q (with -Q suffix) is AEC-Q100 qualified and PPAP capable. The -L22088 suffix denotes a specific tape-and-reel shipment lot identifier and does not imply automotive qualification - always verify the full part number suffix against onsemi's automotive product matrix.
How does the IOFF feature function in NL17SZ126P5T5G-L22088 during system power-down?
When VCC = 0 V, the NL17SZ126P5T5G-L22088 activates its IOFF circuitry, limiting input/output leakage current to ≤10 µA (max) even with 5.5 V applied to A, Y, or OE pins. This prevents back-powering of the VCC rail and eliminates signal contention between powered and unpowered subsystems - a critical requirement for partial power-down architectures in modern embedded systems.
