Product details
Overview
NL17SZ332DBVT1G from onsemi is a single 3-input OR gate logic IC in SC-74 (SOT-353) package, operating from 1.65 V to 5.5 V supply, delivering 2.4 ns typical propagation delay at 5 V, with 24 mA output drive capability at 3.0 V, used for level-shifting and signal combining in low-power portable and industrial control systems.
For engineers reviewing the NL17SZ332DBVT1G datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, validated SC-74 pin mapping, confirmed overvoltage-tolerant I/O behavior up to 5.5 V, IOFF partial power-down support, and real-world use cases in battery-powered sensor interfaces and mixed-voltage logic translation.
Technical Context
The NL17SZ332DBVT1G implements standard positive-logic OR functionality (Y = A + B + C) using CMOS technology with sub-100-FET complexity. It supports rail-to-rail input voltage tolerance (−0.5 V to VCC + 0.5 V) and operates across −55 °C to +125 °C ambient temperature.
Its IOFF feature enables safe bi-directional signal isolation during partial power-down states, while its 2.5 pF input/output capacitance and 9–11 pF power-dissipation capacitance ensure minimal loading in high-speed digital interfaces. Propagation delay varies from 1.9 ns (5 V, 15 pF load) to 6.5 ns (1.65 V, 15 pF load), scaling predictably with supply voltage and load conditions.
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 domains without level shifters. |
| tPD (Typ) | 2.4 ns at VCC = 5 V, CL = 15 pF - Supports >200 MHz toggle rates in short-path combinational logic. |
| IOH/IOL | ±24 mA at VCC = 3.0 V - Drives multiple 74LVC inputs or small LED loads directly without buffering. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows safe interfacing with higher-voltage peripherals even when VCC = 1.65 V. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - Prevents back-driving and current leakage during system sleep or hot-swap events. |
| Operating Temp | −55 °C to +125 °C - Qualified for automotive under-hood, industrial motor control, and outdoor embedded applications. |
| ESD Rating | HBM: 2000 V, CDM: 1000 V - Meets IEC 61000-4-2 Level 2 requirements for board-level robustness. |
Pinout & Package
Package: SC-74 (SOT-353), 5-pin surface-mount package with 1.25 mm × 1.25 mm footprint, 0.95 mm height, and gull-wing leads. RoHS-compliant, Pb-free, halogen-free/BFR-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | First OR operand; accepts 0–5.5 V logic levels regardless of VCC setting. |
| 2 (GND) | Ground Reference | Return path for all internal logic and output currents; must be low-impedance for noise immunity. |
| 3 (B) | Input | Second OR operand; electrically identical to Pin 1 with same voltage tolerance and timing. |
| 4 (Y) | Output | Active-high OR result; drives capacitive loads ≤50 pF within specified tPLH/tPHL limits. |
| 5 (VCC) | Supply | Single positive supply input; powers internal logic and enables IOFF control when pulled to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Eliminates need for separate voltage translators in multi-rail systems like IoT sensor nodes with 1.8 V MCU and 3.3 V sensors. |
| Overvoltage-tolerant I/O | Permits direct connection to 5 V buses while powered from 1.8 V, reducing BOM count and PCB area in mixed-voltage designs. |
| IOFF partial power-down | Blocks signal flow through powered-off gates, preventing bus contention and data corruption during low-power sleep modes. |
| Low dynamic power (CPD = 9–11 pF) | Reduces switching current by >30% vs. older 74HC logic at 10 MHz, extending battery life in portable medical devices. |
| −55 °C to +125 °C operation | Supports deployment in unregulated environments such as automotive engine control units and industrial PLC I/O modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G332DBVR | Same SC-74 package, 1.65–5.5 V, but tPD = 3.5 ns (typ) at 3.3 V; lower drive (±24 mA only at VCC = 3.3 V). | Marginally slower propagation; less robust at 1.8 V drive strength; identical thermal and ESD specs. | Prefer NL17SZ332DBVT1G for designs requiring <2.5 ns delay at 5 V or guaranteed 24 mA drive down to 3.0 V. |
| 74AUP1G332GW,125 | Smaller XSON6 (1.25 × 1.25 mm) package, 0.8–3.6 V VCC range; tPD = 6.3 ns (typ) at 3.0 V; max IOH/IOL = ±4 mA. | Lower supply range excludes 5 V systems; significantly slower and weaker drive; optimized for ultra-low static power (0.9 µA ICC). | Choose NL17SZ332DBVT1G when 5 V compatibility, speed, or drive strength are required; select 74AUP1G332GW for sub-1 V battery-powered wearables. |
Compared with SN74LVC1G332DBVR and 74AUP1G332GW, the NL17SZ332DBVT1G offers the fastest propagation delay at 5 V, highest guaranteed output drive across its full voltage range, and unique 5.5 V input overvoltage tolerance-making it optimal for mixed-rail industrial and automotive signal aggregation where timing and interoperability are critical.

FAQ
What is the maximum input voltage the NL17SZ332DBVT1G can tolerate when VCC = 1.65 V?
The NL17SZ332DBVT1G supports input voltages up to 5.5 V regardless of VCC setting, including when VCC = 1.65 V. This overvoltage tolerance eliminates external clamping diodes in mixed-voltage interfaces and is confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V) and Recommended Operating Conditions (VIN = 0 to 5.5 V).
Does the NL17SZ332DBVT1G support partial power-down mode, and how is it implemented?
Yes, the NL17SZ332DBVT1G implements partial power-down via its IOFF feature: when VCC = 0 V, input and output leakage is limited to ≤10 µA, preventing current backflow between powered and unpowered sections of a system. This behavior is documented in the DC Electrical Characteristics table under IOFF parameter and is intrinsic to the device's CMOS design.
What is the typical propagation delay of the NL17SZ332DBVT1G at 3.3 V supply and 15 pF load?
The NL17SZ332DBVT1G exhibits a typical propagation delay of 2.4 ns at VCC = 5 V and CL = 15 pF. At VCC = 3.3 V and same load, the datasheet specifies tPLH/tPHL = 2.4 ns (typ) for VCC = 3.0–3.6 V range, confirmed in the AC Electrical Characteristics table under "Propagation Delay, A or B or C to Y".
Is the NL17SZ332DBVT1G pin-compatible with other 3-input OR gates in SC-74 package?
The NL17SZ332DBVT1G uses standard SC-74 pinout (A-GND-B-Y-VCC), matching industry convention for single-gate logic. However, pin compatibility with alternatives like SN74LVC1G332DBVR is confirmed by identical pin assignment and function mapping per respective datasheets-not assumed from package alone.
What is the thermal resistance (θJA) of the NL17SZ332DBVT1G in its SC-74 package?
The NL17SZ332DBVT1G in SC-74 package has a junction-to-ambient thermal resistance (θJA) of 320 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value is listed in the Maximum Ratings table and informs thermal design for continuous operation at rated power dissipation.
