Product details
Overview
NL17SZU04DBVT1G from onsemi is a single unbuffered inverter IC designed for low-voltage logic inversion in space-constrained applications, operating from 1.65 V to 5.5 V, delivering 2.1 ns typical propagation delay at 5 V, supporting ±24 mA output drive at 3.0 V, and featuring input overvoltage tolerance up to 5.5 V - used in power management sequencing and level-shifting interfaces in portable instrumentation.
For engineers reviewing the NL17SZU04DBVT1G datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SC-74A), confirmed pin functions, real-world timing and drive capability data, and validated alternative options for logic inversion in industrial and automotive subsystems.
Technical Context
The NL17SZU04DBVT1G implements a single unbuffered CMOS inverter with no internal staging - resulting in minimal propagation delay and reduced capacitive loading. Its IOFF functionality enables partial power-down protection by disabling current flow when VCC = 0 V, while input overvoltage tolerance allows safe interfacing with higher-voltage signals independent of supply rail.
It supports operation across −55 °C to +125 °C, features <100 FET chip complexity, and complies with AEC-Q100 for automotive use when ordered with −Q suffix. The SC-74A package (Case 318BQ) uses a 5-pin configuration with dedicated VCC, GND, input (A), output (Y), and NC terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters |
| tPD (Typ) | 2.1 ns at VCC = 5 V - ensures fast signal inversion critical for clock buffering and timing-critical control paths |
| IOH/IOL | ±24 mA at VCC = 3.0 V - drives moderate fan-out loads such as multiple gate inputs or small LEDs without external buffers |
| Input Overvoltage | Tolerates VIN up to 5.5 V regardless of VCC - permits mixed-supply system interfacing (e.g., 5 V sensor to 3.3 V MCU) |
| IOFF Support | Enables isolation during partial power-down - prevents back-powering and leakage in multi-rail systems during sleep modes |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor controls, and outdoor embedded systems |
Pinout & Package
Package: SC-74A (Case 318BQ), 5-pin surface-mount package measuring 2.0 mm × 2.1 mm × 0.9 mm (max height), RoHS-compliant, Pb-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No-connect - electrically isolated; must be left floating or tied to GND per layout best practice |
| 2 | A | Inverter input - accepts TTL- or CMOS-compatible logic levels; overvoltage tolerant up to 5.5 V |
| 3 | GND | Ground reference - primary return path for output current and internal bias; requires low-impedance PCB connection |
| 4 | Y | Inverted output - active-drive complementary to A; capable of sourcing/sinking up to 24 mA at 3.0 V |
| 5 | VCC | Positive supply - powers internal logic; decoupling capacitor (0.1 µF) required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered architecture | Minimizes propagation delay and dynamic power consumption versus buffered inverters - ideal for high-speed edge-sensitive circuits |
| IOFF partial power-down | Prevents current backflow into powered domains when VCC = 0 V - essential for hot-swap and battery-backed subsystems |
| Input overvoltage tolerance | Accepts 5.5 V inputs even at VCC = 1.65 V - eliminates need for external clamping diodes in mixed-voltage I/O designs |
| Low input capacitance | 2.5 pF typical - reduces loading on driving stage and preserves signal integrity in high-frequency toggle applications |
| AEC-Q100 qualification option | Available with −Q suffix for automotive-grade reliability, PPAP support, and controlled change management |
Applications
| Power Sequencing Control | Level-Shifting Interface |
|---|---|
Use Scenario: Controlling enable/disable timing of multiple voltage rails in FPGA or SoC power-up sequences. IC Role / Device Role / Timing Role: Inverter providing inverted enable signal to secondary regulators or LDOs with active-low EN pins. Use Value: Ensures precise, low-jitter inversion with sub-3 ns delay - avoids race conditions between cascaded power stages. |

Use Scenario: Inverting clock or strobe signals in handheld test equipment where PCB space is limited. IC Role / Device Role / Timing Role: Low-skew inverter placed directly at clock source to drive multiple downstream logic blocks. Use Value: SC-74A footprint (2.0 × 2.1 mm) saves >40% board area vs. SOIC-5 - critical for ultra-compact form factors. |
Use Scenario: Driving LED indicators or small solenoid drivers in door module or lighting control units. IC Role / Device Role / Timing Role: Logic-level translator and current amplifier for MCU GPIO outputs controlling discrete loads. Use Value: ±24 mA drive at 3.0 V supports direct LED drive without external transistor - simplifies schematic and improves MTBF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Higher ICC (up to 10 µA vs. 1 µA typ), slightly slower tPD (3.5 ns @ 3.3 V), same SC-70-5 (SOT-353) footprint but different pinout (VCC/GND swapped) | Not pin-compatible with NL17SZU04DBVT1G; requires PCB redesign due to VCC/GND position mismatch | Select only if existing design uses TI's SC-70-5 layout and tolerates higher quiescent current |
| 74LVC1G04GW,125 | Identical SC-74A package and pinout; tPD = 3.1 ns @ 3.3 V; IOH/IOL = ±32 mA @ 3.3 V; lacks IOFF and input overvoltage tolerance beyond VCC | Suitable for non-power-gated systems where robustness against mixed-voltage faults is not required | Preferred for cost-sensitive industrial applications where enhanced drive strength outweighs overvoltage protection needs |
Compared with SN74LVC1G04DBVR and 74LVC1G04GW,125, the NL17SZU04DBVT1G uniquely combines IOFF, 5.5 V input tolerance, and SC-74A pinout - making it the only choice for partial-power-down mixed-voltage systems requiring zero-layout-change migration from legacy onsemi designs.

FAQ
What is the maximum operating temperature range for NL17SZU04DBVT1G?
The NL17SZU04DBVT1G is rated for operation from −55 °C to +125 °C. This full industrial/automotive temperature range is confirmed in the Recommended Operating Conditions table of the official datasheet (Rev. 14, August 2023). The device maintains specified timing and drive performance across this range, making NL17SZU04DBVT1G suitable for under-hood automotive modules and outdoor industrial controllers.
Does NL17SZU04DBVT1G support partial power-down mode?
Yes, NL17SZU04DBVT1G supports partial power-down via its IOFF feature. When VCC = 0 V, the input and output ports become high-impedance, preventing current backflow between powered and unpowered sections of a system. This behavior is explicitly documented in the Features list and DC Electrical Characteristics section of the NL17SZU04DBVT1G datasheet.
What is the pin 1 marking and orientation for NL17SZU04DBVT1G in SC-74A package?
NL17SZU04DBVT1G in SC-74A package uses "AR" as the top-side marking, with pin 1 located at the bottom-left corner when the marking is read upright. Pin 1 orientation follows Q4 standard (counterclockwise from top-left), matching the pin assignment diagram on page 2 of the datasheet. This matches the SC-74A mechanical drawing (Case 318BQ).
Is NL17SZU04DBVT1G pin-compatible with other TinyLogic inverters in SC-74A?
Yes, NL17SZU04DBVT1G shares identical SC-74A pinout (Pin 1 = NC, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC) with other NL17SZx series devices in the same package, including NL17SZ14 (Schmitt-trigger inverter) and NL17SZ32 (OR gate). This enables functional substitution without PCB modification - provided timing and drive requirements are met.
What is the typical input capacitance of NL17SZU04DBVT1G?
The typical input capacitance (CIN) of NL17SZU04DBVT1G is 2.5 pF, measured at VCC = 5.5 V with VIN = 0 V or VCC. This value is specified in the Capacitive Characteristics table (page 5) of the datasheet and remains consistent across operating voltages - enabling predictable loading on upstream drivers in high-frequency toggle applications.
