Product details
Overview
NL17SZ00DFT2 from onsemi is a single 2-input NAND gate logic IC in SC-88A (SOT-353) package, designed for low-voltage digital signal inversion and control in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 2.4 ns typical propagation delay at 5 V, supports 24 mA IO drive at 3.0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V - enabling interoperability with mixed-supply systems such as USB-powered sensor interfaces.
For engineers reviewing the NL17SZ00DFT2 datasheet, pinout, applications, or equivalent options, key selection considerations include its AEC-Q100 qualified −Q automotive variant, IOFF partial power-down capability, and compatibility with 1.8 V/2.5 V/3.3 V/5 V logic families in portable instrumentation, automotive body control modules, and industrial I/O conditioning circuits.
Technical Context
The NL17SZ00DFT2 implements standard TTL-compatible NAND logic using CMOS technology with rail-to-rail input voltage tolerance and active pull-up/pull-down output stages. Its IOFF feature disables current flow between powered and unpowered sections during partial power-down, preventing back-drive damage in hot-swap or modular subsystems.
Propagation delay varies with supply voltage and load: 2.0 ns (typ) at 5 V with 50 Ω/50 pF, 2.4 ns (typ) at 3.0 V with 1 MΩ/15 pF, and 5.4 ns (typ) at 1.65 V under same AC conditions - confirming robust performance across wide VCC range while maintaining sub-10 ns timing at minimum operating voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V microcontrollers, 3.3 V FPGAs, and legacy 5 V logic without level shifters. |
| tPD (typ) | 2.4 ns at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - supports >200 MHz toggle rates in low-capacitance signal paths. |
| IO Drive | ±24 mA at VCC = 3.0 V - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74LVC inputs without buffering. |
| Input Tolerance | −0.5 V to +6.5 V - allows safe connection to 5 V signals even when VCC = 1.8 V, eliminating external clamping diodes. |
| IOFF Leakage | ≤10 µA at VIN = 5.5 V, VCC = 0 V - prevents signal corruption and power loss in powered-down subsystems. |
| Operating Temp | −55 °C to +125 °C - certified for under-hood automotive, industrial motor control, and outdoor embedded systems. |
Pinout & Package
Package: SC-88A (SOT-353), 5-pin, 2.00 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch, Pb-free, RoHS compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B (Input) | Second logic input; accepts 0–5.5 V regardless of VCC; internally terminated to VCC/GND via ESD protection diodes. |
| 2 | A (Input) | Primary logic input; identical electrical behavior to Pin 1; both inputs share same VIH/VIL thresholds scaled to VCC. |
| 3 | GND | Ground reference for all internal circuitry and output stage; must be connected before applying VCC or inputs. |
| 4 | Y (Output) | Active-low NAND output; drives high to VCC − 0.1 V at −100 µA, low to ≤0.1 V at 100 µA (VCC = 1.65 V). |
| 5 | VCC | Positive supply; powers internal logic and output stage; IOFF function activates automatically when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC Range | Operates from 1.65 V to 5.5 V - eliminates need for separate voltage regulators in multi-rail systems. |
| Overvoltage-Tolerant I/O | Inputs and outputs withstand −0.5 V to +6.5 V - enables safe interfacing with higher-voltage peripherals without external protection. |
| IOFF Partial Power-Down | Blocks current flow between powered/unpowered domains - critical for hot-plug I/O expansion and battery-backed subsystems. |
| Low Propagation Delay | 2.0 ns (typ) at 5 V - supports high-speed control loops in motor drivers and real-time sensor fusion nodes. |
| AEC-Q100 Qualified | Qualified per AEC-Q100 Rev G Grade 1 (−40 °C to +125 °C) - meets automotive electronics reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DBVR | Same SC-70-5 package, 1.65–5.5 V VCC, but tPD = 3.7 ns (typ) at 3.3 V; no IOFF support. | Lacks partial power-down protection; unsuitable for hot-swap or battery-backed systems requiring isolation. | Select when cost sensitivity outweighs IOFF requirement and timing margin ≥1.3 ns is acceptable. |
| 74AUP1G00GW,125 | SC-88A package, lower static current (ICC = 0.9 µA max), but VCC = 0.8–3.6 V only; not 5 V tolerant. | Cannot interface with 5 V peripherals; requires external level shifting in mixed-voltage designs. | Prefer for ultra-low-power 1.8 V/2.5 V IoT edge nodes where 5 V compatibility is unnecessary. |
Compared with SN74LVC1G00DBVR and 74AUP1G00GW,125, the NL17SZ00DFT2 uniquely combines 5 V overvoltage tolerance, IOFF-enabled partial power-down, and 2.4 ns propagation delay in SC-88A - making it the only option among the three qualified for AEC-Q100 automotive applications requiring robust mixed-supply interoperability.

FAQ
What is the maximum operating temperature for NL17SZ00DFT2?
The NL17SZ00DFT2 is rated for continuous operation from −55 °C to +125 °C, meeting AEC-Q100 Grade 1 requirements. This specification is validated per the manufacturer's Recommended Operating Conditions table and applies to the NL17SZ00DFT2 variant with −Q suffix, which is explicitly qualified for automotive use cases including engine bay and transmission control environments.
Does NL17SZ00DFT2 support partial power-down functionality?
Yes, the NL17SZ00DFT2 implements IOFF circuitry that automatically disables current flow through inputs and outputs when VCC = 0 V. Per the datasheet's DC Electrical Characteristics table, IOFF leakage is guaranteed ≤10 µA at VIN = 5.5 V and VCC = 0 V, ensuring signal integrity and power savings in partially powered systems such as hot-swappable I/O cards or battery-backed memory modules.
What package type is used for NL17SZ00DFT2?
The NL17SZ00DFT2 uses the SC-88A (also known as SOT-353) package: a 5-pin surface-mount outline measuring 2.00 mm × 1.25 mm × 0.95 mm with 0.65 mm lead pitch. This is confirmed by the Device Ordering Information table, which lists "NL17SZ00DFT2G" and "NL17SZ00DFT2G−Q*" specifically under the SC−88A column with "DF" suffix and Case 419A designation.
Can NL17SZ00DFT2 interface directly with 5 V logic while powered from 1.8 V?
Yes, the NL17SZ00DFT2 supports input voltages from −0.5 V to +6.5 V independent of VCC, allowing direct connection of 5 V signals even when VCC = 1.8 V. This overvoltage tolerance is specified in the Maximum Ratings table and verified in the DC Electrical Characteristics section, where VIH and VIL thresholds scale with VCC while input structure remains robust up to 6.5 V.
Is NL17SZ00DFT2 RoHS compliant and halogen-free?
Yes, the NL17SZ00DFT2 is explicitly stated as Pb-free, halogen-free/BFR-free, and RoHS compliant in the datasheet's Features section. The "G" suffix in the ordering part number (e.g., NL17SZ00DFT2G) denotes Pb-free packaging, and the device meets JEDEC J-STD-609A Class 1 moisture sensitivity level with UL 94 V-0 flammability rating.
