Product details
Overview
NL17SZ07XV5T2G-L22087 from onsemi is a single non-inverting buffer with open-drain output, designed for level-shifting and wired-OR logic in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 2.1 ns propagation delay at 5 V, sinks up to 24 mA at 3.0 V, tolerates input/output voltages up to 5.5 V, and supports partial power-down via IOFF.
For engineers reviewing the NL17SZ07XV5T2G-L22087 datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain drive capability, overvoltage tolerance, low quiescent current (≤10 µA), and compatibility with mixed-voltage I²C, SMBus, and GPIO interfacing across industrial, computing, and portable electronics.
Technical Context
The NL17SZ07XV5T2G-L22087 implements a CMOS-based non-inverting buffer stage with an open-drain output stage enabling bidirectional bus driving and voltage-level translation without external pull-ups required on the output side. Its IOFF circuitry actively isolates inputs and outputs during power-down, preventing back-drive current when VCC = 0 V.
It features input/output overvoltage tolerance up to 5.5 V independent of VCC, allowing safe interfacing with higher-voltage systems even when powered at 1.65 V. The device uses <100 FETs and is qualified per AEC-Q100 for automotive use when ordered with −Q suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. |
| tPD (typ) | 2.1 ns at VCC = 5 V - Supports high-speed digital control signaling up to ~200 MHz toggle rate. |
| IOL (max) | 24 mA at VCC = 3.0 V - Drives standard LED loads or multiple 10 kΩ pull-up resistors on I²C buses. |
| VIH/VIL | 0.70 × VCC / 0.30 × VCC (VCC ≥ 2.3 V) - Ensures robust noise margin and TTL/CMOS-compatible thresholds. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - Prevents signal corruption and power loss in hot-swap or partial-power-down systems. |
| Overvoltage Tolerance | 5.5 V on inputs and outputs - Allows direct connection to 5 V buses while operating at 1.8 V without level shifters. |
| CIN / COUT | 2.5 pF / 4.0 pF - Minimizes capacitive loading on source and load nodes for clean signal integrity. |
Pinout & Package
NL17SZ07XV5T2G-L22087 is packaged in SOT-553 (Case 463B), a 5-pin, 1.60 mm × 1.20 mm × 0.55 mm surface-mount package with 0.50 mm pitch and Q4 pin 1 orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Positive supply rail - Must be decoupled locally; powers internal logic and output driver. |
| 2 | NC | No connect - Internally unconnected; no external tie required. |
| 3 | A | Non-inverting input - Accepts CMOS/TTL logic levels; overvoltage tolerant to 5.5 V. |
| 4 | Y | Open-drain output - Requires external pull-up; sinks current only; enables wired-AND logic. |
| 5 | GND | Ground reference - Shared return path for supply and signal integrity; must be low-impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Supports single-supply operation across legacy and modern logic families without voltage translation ICs. |
| Input/output overvoltage tolerance (5.5 V) | Eliminates need for external clamping diodes when interfacing with 5 V peripherals while running at 1.8 V. |
| IOFF partial power-down protection | Prevents back-current flow into powered subsystems during sleep or hot-plug events, enhancing system reliability. |
| Low ICC (≤10 µA at 5.5 V) | Reduces static power consumption in battery-powered IoT sensors and always-on monitoring circuits. |
| Small-footprint SOT-553 package | Enables high-density PCB layouts in wearables, medical patches, and compact industrial controllers. |
Applications
| I²C Bus Level Shifting | SMBus Interface Buffering |
|---|---|
Use Scenario: Interfacing a 1.8 V microcontroller I²C master with a 3.3 V sensor slave on shared SDA/SCL lines. IC Role / Device Role / Timing Role: Open-drain buffer placed on SDA line to translate logic levels bidirectionally while preserving timing compliance. Use Value: Eliminates discrete MOSFET translators; maintains tBUF and tHD:DAT specifications due to sub-3 ns propagation delay and low capacitance. | Use Scenario: Isolating SMBus alert lines between a 5 V baseboard management controller and 3.3 V daughterboard peripherals. IC Role / Device Role / Timing Role: Non-inverting open-drain repeater that aggregates multiple ALRT# signals onto one shared interrupt bus. Use Value: IOFF prevents leakage-induced false interrupts during board power sequencing; 24 mA sink drives long traces with heavy capacitive loading. |
| GPIO Expansion Interface | LED Driver Enable Stage |
Use Scenario: Extending GPIO count from an MCU to control multiple 5 V logic-level enable inputs on PMICs or analog switches. IC Role / Device Role / Timing Role: Logic buffer with overvoltage-tolerant input accepting MCU GPIO, driving 5 V loads via open-drain output. Use Value: Input tolerance allows direct 5 V-safe connection without series resistors; NC pin simplifies layout by eliminating unused terminal routing. | Use Scenario: Driving common-anode LEDs from a 3.3 V microcontroller GPIO where cathode-side switching is preferred. IC Role / Device Role / Timing Role: Open-drain output stage sinking LED current (up to 24 mA at 3.0 V) with non-inverting control logic. Use Value: Eliminates need for external N-channel MOSFET; built-in overvoltage tolerance protects against LED string transients up to 5.5 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Same function, 5-pin SOT-23 package; slightly higher ICC (20 µA max); no IOFF feature. | Lacks partial power-down protection; unsuitable for hot-swap or multi-rail power-gated systems. | Select when footprint compatibility with legacy SOT-23 layouts is required and IOFF is not needed. |
| 74LVC1G07GW,125 | 5-pin TSSOP package; identical electrical specs including IOFF and overvoltage tolerance; RoHS-compliant. | Larger 2.1 mm × 1.25 mm footprint; less suitable for ultra-dense portable designs. | Select when board assembly prefers TSSOP handling or requires JEDEC-standard marking and traceability. |
Compared with NL17SZ07XV5T2G-L22087, SN74LVC1G07DBVR offers pin-compatible SOT-23 placement but sacrifices IOFF protection, while 74LVC1G07GW,125 matches all key specs but trades the ultra-compact SOT-553 size for broader manufacturability and test access.

FAQ
What is the maximum sink current capability of the NL17SZ07XV5T2G-L22087 at 3.0 V supply?
The NL17SZ07XV5T2G-L22087 can sink up to 24 mA at VCC = 3.0 V, as specified in the DC Electrical Characteristics table under IOL conditions. This rating ensures reliable driving of standard logic inputs, LEDs, or multiple parallel pull-up resistors on open-drain buses like I²C without exceeding output voltage limits (VOL ≤ 0.4 V).
Does the NL17SZ07XV5T2G-L22087 support partial power-down functionality?
Yes, the NL17SZ07XV5T2G-L22087 supports partial power-down via its IOFF feature, which actively disables input and output paths when VCC = 0 V. This prevents back-current flow and signal corruption in systems with mixed power domains, and is confirmed in the Features section and DC Electrical Characteristics (IOFF ≤ 10 µA).
What package type is used for the NL17SZ07XV5T2G-L22087?
The NL17SZ07XV5T2G-L22087 uses the SOT-553 package (Case 463B), a 5-pin, 1.60 mm × 1.20 mm × 0.55 mm surface-mount outline with 0.50 mm pitch and Q4 pin 1 orientation, as documented in the Device Ordering Information table and Package Dimensions section.
Can the NL17SZ07XV5T2G-L22087 tolerate 5 V inputs while operating at 1.8 V VCC?
Yes, the NL17SZ07XV5T2G-L22087 supports input and output overvoltage tolerance up to 5.5 V regardless of VCC level, enabling safe 5 V signal interfacing even when powered at 1.65 V. This is explicitly stated in the Features list and verified in the Maximum Ratings (VIN = −0.5 V to +6.5 V) and Recommended Operating Conditions tables.
Is the NL17SZ07XV5T2G-L22087 qualified for automotive applications?
The base NL17SZ07XV5T2G-L22087 is not automotive-qualified; however, the −Q suffix variant (e.g., NL17SZ07XV5T2G−Q) is AEC-Q100 qualified and PPAP capable. The datasheet confirms this distinction in the Features section and DEVICE ORDERING INFORMATION footnote, specifying that −Q denotes automotive and other applications requiring unique site and control change requirements.
