Product details
Overview
NL17SZ125P5T5G-L22088 from onsemi is a single non-inverting 3-state buffer IC designed for level-shifting and bus isolation in low-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers 2.3 ns propagation delay at 5 V, supports ±24 mA drive at 3.0 V, and features IOFF partial power-down protection - used in portable MCU I/O expansion and battery-powered sensor interface circuits.
For engineers reviewing the NL17SZ125P5T5G-L22088 datasheet, pinout, applications, or equivalent options, key selection criteria include VCC voltage range compatibility, 3-state enable timing (tPZH/tPHZ), overvoltage-tolerant inputs up to 5.5 V, and SOT-953 package footprint constraints.
Technical Context
The NL17SZ125P5T5G-L22088 implements a single-channel non-inverting buffer with active-low 3-state output control (OE). Its logic function follows A → Y when OE = L, and high-impedance (Z) when OE = H - enabling bidirectional bus driving without contention.
It integrates IOFF circuitry that disables input/output paths when VCC = 0 V, preventing back-driving during partial power-down. Inputs tolerate voltages up to 5.5 V regardless of VCC, supporting mixed-supply interfacing between 1.8 V, 3.3 V, and 5 V domains.
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 families |
| tPLH / tPHL | 2.0 ns typ at VCC = 5 V, CL = 15 pF - ensures fast signal routing in high-speed digital control paths |
| IOFF Support | Active when VCC = 0 V - prevents current leakage and bus contention during system sleep or hot-swap |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe connection to higher-voltage peripherals without level shifters |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive multiple CMOS loads or short PCB traces |
| Operating Temp | −55 °C to +125 °C - qualified for industrial and extended-temperature embedded applications |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets robustness requirements for handling and board assembly |
Pinout & Package
SOT-953 (5-pin, 1.0 mm × 0.8 mm, 0.35 mm pitch) - ultra-compact surface-mount package optimized for space-constrained portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A | Non-inverting data input; accepts 0–5.5 V regardless of VCC |
| 2 | GND | Ground reference for all internal circuitry and output termination |
| 3 | OE | Active-low 3-state enable; drives Y to high-Z when high |
| 4 | Y | Buffered non-inverting output; tri-states when OE = H |
| 5 | VCC | Positive supply rail; powers internal logic and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operation | 1.65–5.5 V supports single-supply flexibility across legacy and modern logic families |
| Overvoltage-tolerant inputs | Inputs withstand up to 5.5 V even at VCC = 1.65 V - eliminates need for external clamping diodes |
| IOFF partial power-down | Blocks current flow between A/Y and GND/VCC when VCC = 0 V - critical for hot-plug and multi-rail systems |
| Low propagation delay | 2.0 ns typical at 5 V enables use in timing-critical control paths such as SPI clock buffering |
| Pb-free & RoHS compliant | Meets global environmental compliance standards including halogen-free/BFR-free construction |

This overvoltage tolerance is explicitly specified in the Absolute Maximum Ratings table and confirmed across all operating conditions in the datasheet.
Does NL17SZ125P5T5G-L22088 support partial power-down protection?
Yes, NL17SZ125P5T5G-L22088 includes IOFF circuitry that automatically disables both input and output paths when VCC = 0 V. This prevents back-current flow and bus contention during partial power-down scenarios - a key feature validated in the datasheet's Functional Description and DC Electrical Characteristics sections.
What is the propagation delay of NL17SZ125P5T5G-L22088 at 3.3 V supply?
At VCC = 3.3 V, the NL17SZ125P5T5G-L22088 exhibits a typical propagation delay (tPLH/tPHL) of 2.5 ns under RL = 1 MΩ and CL = 15 pF conditions - as specified in the AC Electrical Characteristics table. This value is measured across the full temperature range and reflects actual gate-level timing performance.
Which package type does NL17SZ125P5T5G-L22088 use?
NL17SZ125P5T5G-L22088 uses the SOT-953 package - a 5-pin, 1.0 mm × 0.8 mm, 0.35 mm pitch ultra-thin surface-mount outline. Pin 1 orientation is rotated 180° clockwise, as documented in the Device Ordering Information table on page 7 of the datasheet.
Is NL17SZ125P5T5G-L22088 qualified for automotive applications?
