Product details
Overview
NL17SZ06DBVT1G from onsemi is a single CMOS inverter with open-drain output, designed for level-shifting and wired-OR logic interfacing in low-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers 2.1 ns propagation delay at 5 V, supports 24 mA sink current at 3.0 V, and features input/output overvoltage tolerance up to 5.5 V - enabling robust interface between mixed-supply domains such as 1.8 V logic driving 3.3 V or 5 V bus lines.
For engineers reviewing the NL17SZ06DBVT1G datasheet, pinout, applications, or equivalent options, key selection considerations include open-drain drive capability, partial power-down (IOFF) support, wide VCC range compatibility, and SC-74A package footprint for space-constrained PCB layouts.
Technical Context
The NL17SZ06DBVT1G implements a single inverting buffer stage with an open-drain NMOS output stage, requiring an external pull-up resistor to define high-level logic voltage. Its IOFF feature disables input/output leakage during partial power-down, preventing back-driving of powered rails when VCC = 0 V.
It supports rail-to-rail input operation up to 5.5 V independent of VCC, and maintains guaranteed switching thresholds across 1.65–5.5 V supply range - VIH = 0.70×VCC (min) and VIL = 0.30×VCC (max) for VCC ≥ 2.3 V - ensuring reliable noise margins in mixed-voltage signal translation.
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 |
| tPD (Typ) | 2.1 ns at VCC = 5 V - supports >200 MHz toggle rates in non-critical timing paths |
| IOL (Max) | 24 mA at VCC = 3.0 V - drives standard TTL loads or multiple CMOS inputs via pull-up |
| Input Overvoltage | Up to 5.5 V regardless of VCC - allows safe interfacing to higher-voltage buses without clamping diodes |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents current injection into unpowered sections during system sleep modes |
| Package | SC-74A (SOT-23-5) - 3.0 mm × 1.5 mm footprint compatible with automated SMT assembly |
Pinout & Package
SC-74A (Case 318BQ) is a 5-pin surface-mount package with gull-wing leads, 0.95 mm height, and 0.65 mm pitch. Pin 1 is marked by a notch or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No-connect terminal | Internally unconnected - must remain floating; no PCB trace or component attachment |
| 2 (A) | Inverter input | CMOS-compatible digital input accepting 0–5.5 V; no internal pull-up/down |
| 3 (GND) | Ground reference | Return path for output sink current and internal bias; must be low-impedance |
| 4 (Y) | Open-drain output | NMOS drain terminal - requires external pull-up to define VOH; sinks up to 24 mA |
| 5 (VCC) | Positive supply | Power rail for internal logic; decoupling capacitor (0.1 µF) recommended within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operation | 1.65–5.5 V supply range enables drop-in use across legacy and modern low-voltage systems |
| IOFF partial power-down | Blocks I/O leakage when VCC = 0 V - essential for hot-swap and multi-rail power sequencing |
| Overvoltage-tolerant inputs/outputs | Withstands 5.5 V signals regardless of VCC - eliminates need for external level-shifters in mixed-supply interfaces |
| Low propagation delay | 2.1 ns typical tPD at 5 V supports fast edge-sensitive applications like clock enable gating |
| Pb-free, RoHS-compliant | Meets J-STD-609 Category 1 moisture sensitivity (MSL 1) and UL 94 V-0 flammability rating |
Applications
| Level-Shifting Interface | Wired-OR Bus Driver |
|---|---|
Use Scenario: Translating 1.8 V GPIO output to control a 3.3 V I²C bus pull-up rail. IC Role / Device Role / Timing Role: Open-drain inverter provides bidirectional voltage translation without direction control logic. Use Value: Eliminates discrete MOSFET level shifters; leverages built-in overvoltage tolerance to safely interface sub-2 V logic to 3.3 V domain. |
Use Scenario: Driving shared interrupt line (INT#) from multiple microcontrollers with active-low assertion. IC Role / Device Role / Timing Role: Inverts local interrupt signal and outputs open-drain to enable wired-OR summation on common bus. Use Value: Ensures clean bus arbitration with no contention; IOFF prevents leakage when one controller powers down while others remain active. |
| Power Sequencing Monitor | Reset Signal Inversion |
Use Scenario: Monitoring 5 V power rail status using a 3.3 V microcontroller ADC input. IC Role / Device Role / Timing Role: Configured as active-low detector: VCC = 3.3 V, input tied to 5 V rail via resistive divider, output pulled to 3.3 V. Use Value: Provides rail-agnostic monitoring - input tolerates 5 V directly, eliminating divider and protection diode. |
Use Scenario: Inverting active-high reset signal from PMIC to match active-low reset requirement of FPGA. IC Role / Device Role / Timing Role: Single-stage inversion with open-drain output pulled to FPGA VCCO (2.5 V or 3.3 V). Use Value: Delivers sub-5 ns delay and guaranteed logic thresholds across full VCC range - ensures deterministic reset timing margin. |
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 |
|---|---|---|---|
| SN74LVC1G06DBVR | Same SC-70-5 (SC-74A) package; 1.65–5.5 V VCC; 3.5 ns tPD (typ) at 3.3 V; no IOFF | Lacks partial power-down protection - unsuitable for systems with asymmetric power sequencing | Select when IOFF is not required and slightly relaxed timing is acceptable |
| 74LX1G06GW,125 | SC-88A (SOT-353) package; 1.65–5.5 V VCC; 3.0 ns tPD (typ) at 5 V; includes IOFF | Smaller 2.1 mm × 1.25 mm footprint but different pinout - requires PCB layout change | Select when board area is critical and re-layout is feasible |
Compared with SN74LVC1G06DBVR and 74LX1G06GW,125, the NL17SZ06DBVT1G uniquely combines SC-74A packaging, sub-2.5 ns speed at 5 V, and IOFF - making it optimal for compact, multi-rail embedded systems requiring guaranteed power-down isolation.

FAQ
What is the maximum sink current capability of the NL17SZ06DBVT1G at 3.3 V supply?
The NL17SZ06DBVT1G guarantees a maximum output low voltage (VOL) of 0.4 V when sinking 24 mA at VCC = 3.0 V, and 0.55 V at 24 mA when VCC = 4.5 V. At 3.3 V, interpolation from datasheet curves confirms sustained 24 mA sink capability with VOL ≤ 0.45 V - sufficient to drive standard TTL loads or up to 10x 74LVC inputs with appropriate pull-up sizing. This performance is validated across −55 °C to +125 °C.
Does the NL17SZ06DBVT1G support true bidirectional level shifting?
No - the NL17SZ06DBVT1G is a unidirectional inverter with open-drain output and does not provide automatic bidirectional translation. It can translate low-to-high voltage levels (e.g., 1.8 V input → 3.3 V output via pull-up), but cannot pass signals from high-voltage side to low-voltage side without additional circuitry. Its overvoltage-tolerant input allows safe connection to higher-voltage nodes, but logic flow remains strictly input A → output Y.
Can the NC pin (Pin 1) on the NL17SZ06DBVT1G be used as a thermal pad or grounded for improved thermal performance?
No - Pin 1 of the NL17SZ06DBVT1G is explicitly designated as "NC" (no connect) in the datasheet pin assignment table and functional diagram. It is internally unconnected and must remain electrically floating. Connecting it to GND, VCC, or a thermal pad violates the device's qualified SC-74A mechanical construction and may cause parametric shifts or reliability issues. Thermal dissipation relies solely on the standard leadframe path through Pins 3 (GND) and 5 (VCC).
Is the NL17SZ06DBVT1G qualified for automotive applications?
The NL17SZ06DBVT1G itself is not automotive-qualified; however, the NL17SZ06DFT2G−Q variant (SC-88A package) carries the −Q suffix and is AEC-Q100 qualified and PPAP capable. The NL17SZ06DBVT1G uses the same die but is packaged in SC-74A and rated for industrial temperature range (−55 °C to +125 °C). For automotive use, engineers must select the −Q qualified version and verify compliance with their Tier 1's specific PPAP documentation requirements.
How does the IOFF feature of the NL17SZ06DBVT1G behave during power-down sequences?
When VCC = 0 V, the NL17SZ06DBVT1G activates its IOFF circuitry to limit both input and output leakage current to ≤10 µA (max), effectively isolating the device from powered circuitry connected to pins A and Y. This prevents back-powering of unpowered sections and avoids false triggering in multi-rail systems - for example, when a 3.3 V domain remains active while the 1.8 V domain shuts down. The feature is intrinsic to the silicon design and requires no external control signals.
