Product details
Overview
NL17SZ02DFT2G-L22038 from onsemi is a single 2-input NOR gate logic IC in SC-88A (SOT-353) package, designed for low-voltage operation from 1.65 V to 5.5 V, delivering 2.4 ns typical propagation delay at 5 V, overvoltage-tolerant inputs/outputs up to 5.5 V, and ±24 mA drive capability at 3.0 V - used in level-shifting, signal inversion, and enable/disable control in portable power management and interface logic circuits.
For engineers reviewing the NL17SZ02DFT2G-L22038 datasheet, pinout, applications, or equivalent options, this page provides verified pin assignments, real-world timing behavior across voltage ranges, IOFF partial power-down support, and validated alternatives for space-constrained 5-pin logic designs.
Technical Context
The NL17SZ02DFT2G-L22038 implements complementary CMOS logic with <100 FETs complexity, supporting rail-to-rail input operation and active-drive output stages capable of sourcing/sinking 24 mA at 3.0 V. Its IOFF feature enables safe bus hold during partial power-down by disabling current flow when VCC = 0 V.
Propagation delay varies with supply voltage and load: 5.3 ns (min) at 1.65–1.95 V, 2.3 ns (typ) at 3.0–3.6 V, and 1.9 ns (typ) at 4.5–5.5 V under 15 pF load; input/output capacitance is 2.5 pF each, and power dissipation capacitance is 9 pF at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| tPD (typ) | 2.4 ns at VCC = 5 V, CL = 15 pF - enables high-speed enable/disable sequencing in clock gating and reset distribution. |
| IOFF Support | Active when VCC = 0 V - prevents back-powering and signal contention in hot-swap or multi-rail systems. |
| Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive LED indicators, small MOSFET gates, or multiple 74LVC inputs. |
| Input Tolerance | Inputs tolerant to 5.5 V regardless of VCC - allows mixed-supply system integration where input signals exceed local rail. |
| Package | SC-88A (SOT-353), 5-pin, 2.00 × 1.25 × 0.95 mm - fits high-density PCB layouts with 0.65 mm pitch and JEDEC-compliant footprint. |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets industrial reliability requirements without external protection diodes. |
Pinout & Package
SC-88A (Case 419A) package: 5-pin, surface-mount, 2.00 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | First logic input - accepts 0 V to 5.5 V independent of VCC; compatible with 1.8 V/3.3 V/5 V drivers. |
| 2 | B | Second logic input - identical electrical behavior to Pin 1; both inputs share same VIH/VIL thresholds. |
| 3 | GND | Ground reference - must be connected before VCC to ensure proper power-up sequencing and latchup immunity. |
| 4 | Y | Output - active-drive NOR function (Y = A + B); sinks up to 32 mA or sources up to 24 mA at 3.0 V. |
| 5 | VCC | Positive supply - powers internal circuitry; IOFF activates automatically if disconnected while inputs remain asserted. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Accepts 0–5.5 V inputs at any VCC from 1.65–5.5 V - eliminates need for external clamping or translation in mixed-voltage systems. |
| Partial power-down (IOFF) | Blocks >99% leakage between inputs/outputs when VCC = 0 V - critical for battery-backed subsystems and hot-plug interfaces. |
| Low dynamic power | CPD = 9 pF at 3.3 V - reduces switching current consumption in high-frequency enable/disable paths (e.g., sensor wake-up control). |
| High-speed performance | Sub-3 ns tPD at 3.3 V and 4.5–5.5 V - supports >200 MHz toggle rates in clock-enable trees and state-machine control paths. |
| Small-footprint packaging | SC-88A footprint occupies only 2.5 mm² PCB area - ideal for wearables, IoT edge nodes, and compact power sequencers. |
Applications
| Power Sequencing Control | Level-Shifting Interface |
|---|---|
|
Use Scenario: Controlling startup order of multiple DC-DC converters in FPGA or SoC power domains. IC Role / Device Role / Timing Role: NOR gate configured as active-low OR function to assert global reset only after all rails stabilize.

Use Scenario: Translating 1.8 V GPIO outputs to 3.3 V logic levels for MCU peripheral enable lines. IC Role / Device Role / Timing Role: Level translator using VCC = 3.3 V and 1.8 V input signals - leveraging input overvoltage tolerance. Use Value: Eliminates discrete resistor-divider or dedicated level shifter ICs, reducing BOM count and layout area by 40%. |
| LED Driver Enable Logic | Hot-Swap Bus Isolation |
|
Use Scenario: Enabling high-brightness LEDs in portable medical devices via microcontroller PWM signals. IC Role / Device Role / Timing Role: Inverting driver stage that combines two MCU control lines to activate LED current sink only when both are high. Use Value: ±24 mA drive at 3.0 V directly switches LED strings up to 20 mA without external transistor buffering. |
Use Scenario: Isolating I²C or UART lines during live insertion of modular sensor boards into base stations. IC Role / Device Role / Timing Role: Signal gate that blocks communication until power stabilization is confirmed via IOFF-enabled isolation. Use Value: Prevents bus contention and data corruption during hot-swap events by cutting off signal paths before VCC ramps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Same SC-70-5 (SC-74A) package; 3.3 V optimized (1.65–5.5 V), 3.7 ns tPD at 3.3 V, no IOFF support. | Lacks partial power-down protection - unsuitable for systems requiring VCC-independent input blocking. | Select when cost sensitivity outweighs IOFF requirement and layout allows SC-74A footprint. |
| MC74VHC1G02DTT1G | SOT-23-5 package; 2–5.5 V range, 7.5 ns tPD at 3.3 V, IOFF supported, but larger 2.92 × 1.62 mm footprint. | Slower propagation and larger size limit use in ultra-compact, high-speed designs. | Choose when legacy SOT-23 compatibility is required and board space permits 2.5× larger footprint. |
Compared with SN74LVC1G02DBVR and MC74VHC1G02DTT1G, NL17SZ02DFT2G-L22038 delivers the fastest propagation (2.4 ns), smallest SC-88A footprint, and guaranteed IOFF - making it optimal for miniaturized, multi-rail systems needing deterministic power-down behavior.

FAQ
What is the maximum operating temperature range for NL17SZ02DFT2G-L22038?
The NL17SZ02DFT2G-L22038 is rated for operation from −55 °C to +125 °C per its Recommended Operating Conditions table. This extended range supports deployment in under-hood automotive modules, industrial motor drives, and outdoor wireless infrastructure where ambient temperatures exceed standard commercial limits. The device maintains full functionality and timing specifications across this full range without derating.
Does NL17SZ02DFT2G-L22038 support true bidirectional signal translation?
No, NL17SZ02DFT2G-L22038 is a unidirectional 2-input NOR gate with defined input (Pins 1 and 2) and output (Pin 4) terminals. While its inputs tolerate voltages up to 5.5 V regardless of VCC, it does not provide automatic direction sensing or bus arbitration. For bidirectional level shifting, dedicated translators like the NTS0102 or PCA9306 are required instead of NL17SZ02DFT2G-L22038.
Can NL17SZ02DFT2G-L22038 be used with a 1.8 V supply and 3.3 V input signals?
Yes, NL17SZ02DFT2G-L22038 supports this configuration: set VCC = 1.8 V and apply 3.3 V signals to Pins 1 or 2. Its inputs are overvoltage tolerant up to 5.5 V, and VIH is specified as 0.65 × VCC (1.17 V min) at 1.65–1.95 V, ensuring reliable recognition of 3.3 V as a valid HIGH. Output swing will be rail-to-rail relative to 1.8 V, so downstream devices must accept 1.8 V logic levels.
Is NL17SZ02DFT2G-L22038 pin-compatible with other TinyLogic® NOR gates in SC-88A?
Yes, NL17SZ02DFT2G-L22038 shares identical SC-88A pinout (A-B-GND-Y-VCC) with other single-gate TinyLogic® devices in the same package, including NL17SZ04 (inverter), NL17SZ08 (AND), and NL17SZ32 (OR). This enables drop-in functional substitution in existing layouts without PCB revision - provided timing and drive requirements are met for the new logic function.
What is the quiescent supply current (ICC) of NL17SZ02DFT2G-L22038 at 5.5 V?
At VCC = 5.5 V and TA = 25 °C, the NL17SZ02DFT2G-L22038 draws a maximum quiescent supply current (ICC) of 10 µA, with typical value near 1.0 µA. This ultra-low static power enables use in always-on monitoring circuits, such as tamper-detection logic or battery-backed real-time clock enable paths, where sub-microamp standby current is critical for multi-year operation.
