Product details
Overview
NL17SZ05DBVT1G from onsemi is a single CMOS inverter with open-drain output, designed for level-shifting, wired-OR logic, and I²C bus interface applications. It operates from 1.65 V to 5.5 V, delivers 2.4 ns typical propagation delay at 5 V, supports 24 mA output sink current at 3.0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V.
For engineers reviewing the NL17SZ05DBVT1G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain compatibility with mixed-voltage systems, IOFF partial power-down protection, ±50 mA absolute maximum output current rating, and SC−74A (SOT−23−5) package footprint constraints.
Technical Context
The NL17SZ05DBVT1G implements a single-stage CMOS inverter topology with an unbuffered open-drain N-channel MOSFET output stage, enabling bidirectional voltage translation without external pull-ups in I²C mode. Its input structure includes overvoltage tolerance circuitry allowing safe operation with VIN up to 5.5 V independent of VCC.
IOFF functionality disables both input and output leakage paths when VCC = 0 V, preventing back-powering of powered-down rails. The device exhibits rail-to-rail input switching thresholds (VIH = 0.7×VCC, VIL = 0.3×VCC) and maintains guaranteed VOL ≤ 0.42 V at IOL = 24 mA and VCC = 3.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interfacing across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 2.4 ns at VCC = 5 V - enables high-speed signal inversion in timing-critical control paths |
| IOL Max | 24 mA at VCC = 3.0 V - drives standard I²C bus loads and discrete LEDs without external buffer |
| Input Overvoltage | Up to 5.5 V - allows safe connection to higher-voltage buses while VCC remains at 1.8 V or 2.5 V |
| IOFF Support | Active at VCC = 0 V - prevents current leakage into powered-down subsystems during partial shutdown |
| Package | SC−74A (SOT−23−5) - 2.9 mm × 1.6 mm footprint compatible with high-density PCB layouts |
| ESD Rating | HBM 2000 V - meets industrial-grade robustness requirements for board-level handling and assembly |
Pinout & Package
SC−74A (SOT−23−5) package: 2.9 mm × 1.6 mm body, 0.95 mm pitch, 5-terminal surface-mount construction with gull-wing leads. Pin 1 marked by dot; pin 1 orientation is Q4 per tape-and-reel specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No-connect terminal | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 2 (A) | Inverter input | CMOS-compatible digital input accepting 0–5.5 V; VIH/VIL thresholds scale with VCC |
| 3 (GND) | Ground reference | Primary return path for output sink current and internal bias networks |
| 4 (Y) | Open-drain output | N-channel MOSFET drain; requires external pull-up for HIGH state; sinks up to 24 mA |
| 5 (VCC) | Positive supply | Power rail for internal logic; powers input buffers and output driver; range 1.65–5.5 V |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operating range | 1.65 V to 5.5 V enables single part to replace multiple voltage-specific inverters in multi-rail systems |
| Open-drain output architecture | Supports wired-AND logic, I²C/SMBus compatibility, and level translation without direction control pins |
| IOFF partial power-down | Blocks >99% of input/output leakage when VCC = 0 V, critical for battery-backed or hot-swap subsystems |
| Overvoltage-tolerant inputs | Accepts 5.5 V signals regardless of VCC setting - eliminates need for external clamping diodes |
| Low dynamic power consumption | CPD = 9–11 pF enables <1 µW no-load power at 1 MHz, suitable for ultra-low-power sensor nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter-with-open-drain-output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G05DBVR | TI part uses same SC−74A package but specifies only 1.65–5.5 V VCC and lacks explicit IOFF support in datasheet | Not qualified for partial power-down use cases requiring guaranteed zero leakage at VCC = 0 V | Select NL17SZ05DBVT1G when IOFF functionality is required for hot-swap or battery backup systems |
| 74LVC1G05GW,125 | Nexperia part in SC−74A offers identical VCC range and open-drain output but specifies max IOL = 32 mA at 3.3 V vs. 24 mA at 3.0 V | Better suited for higher-current load driving; however, input overvoltage tolerance capped at VCC + 0.3 V, not 5.5 V | Choose NL17SZ05DBVT1G for mixed-voltage interfaces where inputs may exceed VCC by >0.3 V |
Compared with SN74LVC1G05DBVR and 74LVC1G05GW,125, the NL17SZ05DBVT1G uniquely combines 5.5 V input overvoltage tolerance with verified IOFF behavior and industrial temperature range (−55°C to +125°C), making it optimal for ruggedized, multi-rail embedded control designs.

FAQ
What is the maximum output sink current supported by NL17SZ05DBVT1G at 3.0 V supply?
The NL17SZ05DBVT1G supports up to 24 mA output sink current at VCC = 3.0 V, as specified in the DC Electrical Characteristics table under VOL test conditions. This value is guaranteed across the full operating temperature range (−55°C to +125°C) and ensures reliable drive capability for standard I²C bus loads and indicator LEDs without external buffering.
Does NL17SZ05DBVT1G support partial power-down (IOFF) functionality?
Yes, NL17SZ05DBVT1G explicitly supports IOFF functionality, which disables input and output leakage paths when VCC = 0 V. Per the datasheet, IOFF leakage is limited to 1.0 µA (typ) and 10 µA (max), preventing back-powering of powered-down subsystems - a critical feature for hot-swap and battery-backed applications.
Can NL17SZ05DBVT1G accept 5 V input signals while operating at 1.8 V VCC?
Yes, NL17SZ05DBVT1G features overvoltage-tolerant inputs rated up to 5.5 V regardless of VCC level. When VCC = 1.8 V, the device safely accepts 5 V logic signals on pin A without damage or functional degradation, eliminating the need for external level-shifting components in mixed-voltage interfaces.
What package type is used for NL17SZ05DBVT1G?
NL17SZ05DBVT1G is packaged in SC−74A (also known as SOT−23−5), a 5-pin surface-mount package measuring 2.9 mm × 1.6 mm with 0.95 mm lead pitch. Pin 1 is marked by a dot and oriented in Q4 position per tape-and-reel packaging specifications.
Is NL17SZ05DBVT1G suitable for automotive applications?
The NL17SZ05DBVT1G itself is not automotive-qualified; however, its automotive-grade variant NLV17SZ05DBVT1G (with NLV prefix) is AEC−Q100 qualified and PPAP capable. Standard NL17SZ05DBVT1G is rated for −55°C to +125°C operation and meets industrial reliability requirements but lacks formal automotive certification.
