Product details
Overview
NLV74HC03ADR2G from onsemi is a quad 2-input NAND gate with open-drain outputs, designed for wired-AND logic and sinking-current applications such as LED driving and level translation. It operates from 2.0 V to 6.0 V, delivers up to 25 mA sink current per output, supports −55 °C to +125 °C industrial temperature range, and features 10 LSTTL load drive capability with external pullup resistors.
For engineers reviewing the NLV74HC03ADR2G datasheet, pinout, applications, or equivalent options, this device is selected for robust open-drain interfacing in mixed-voltage systems, bus arbitration, and active-low signal conditioning where high noise immunity and CMOS/TTL compatibility are required.
Technical Context
The NLV74HC03ADR2G implements four independent NAND gates, each with an N-channel open-drain output stage capable of sinking up to 25 mA. Its inputs are compatible with both standard CMOS and LSTTL logic families when used with appropriate pullup resistors.
Propagation delay is specified at 20 ns (max) at VCC = 6.0 V, and output transition time is 13 ns (max) under same conditions. Input leakage remains ≤ ±1.0 µA across full temperature range, and quiescent supply current is ≤ 40 µA at VCC = 6.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND with open-drain outputs - enables wired-AND bus structures and flexible voltage-level interfacing. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports operation across 3.3 V and 5 V systems without level shifters. |
| Output Sink Current | ±25 mA per pin - sufficient to directly drive LEDs or interface with TTL loads using external pullups. |
| Propagation Delay | 20 ns max at VCC = 6.0 V - ensures timing predictability in high-speed digital control paths. |
| Operating Temperature | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments. |
| Input Leakage Current | ≤ ±1.0 µA at TA = +125 °C - minimizes unintended biasing in high-impedance or battery-powered nodes. |
| ESD Rating | >2000 V HBM - provides robust handling during PCB assembly and system integration. |
Pinout & Package
Package: SOIC-14 (Case 751A), 8.75 mm × 3.90 mm body, 1.27 mm pitch, Pb-free, RoHS compliant.

| 2, 5, 10, 13 | Input B | Second input of NAND gate 1–4; identical electrical behavior to Pin A group. |
| 3, 6, 8, 11 | Output Y* | Open-drain output - requires external pullup; sinks current only; no active high drive. |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry. |
| 14 | VCC | Positive supply rail; powers all four gates; must be decoupled locally. |
Key Features

| AEC-Q100 qualification | Automotive-grade variant available (NLV74HC03ADR2G−Q); this part shares same die and process flow. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Adding discrete open-drain outputs to extend PLC rack I/O for sinking-type sensors and actuators. IC Role / Device Role / Timing Role: Logic-level translator and current sink for 24 V DC field devices via external pullup to 24 V. Use Value: Eliminates need for discrete transistors or optocouplers; reduces BOM count while maintaining galvanic isolation via external resistor network. | Use Scenario: Driving low-side LED indicators and diagnostic lamps in door modules and junction boxes. IC Role / Device Role / Timing Role: NAND gate configured as inverter (one input tied high) to enable/disable LED current path with active-low control. Use Value: Delivers 25 mA sink per channel at 12 V supply - sufficient for high-brightness status LEDs without external drivers. |
| Legacy System Bus Arbitration | Multi-Voltage Level Translation |
Use Scenario: Implementing shared interrupt lines across multiple microcontrollers operating at different supply voltages. IC Role / Device Role / Timing Role: Wired-AND bus driver - each MCU pulls its NLV74HC03ADR2G output low to assert shared IRQ line. Use Value: Ensures deterministic bus contention resolution with no shoot-through risk; supports mixed 3.3 V/5 V controller domains. | Use Scenario: Translating 1.8 V GPIO signals to 5 V logic thresholds in sensor interface boards. IC Role / Device Role / Timing Role: Level-shifting buffer - input accepts 1.8 V CMOS levels; output pulled to 5 V rail sinks current to generate valid 5 V logic LOW. Use Value: Achieves bidirectional voltage translation without direction control pins or complex ICs - simplifies layout and firmware. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC03APWR | 3.3 V only (1.65–3.6 V), lower propagation delay (11 ns), higher speed but narrower voltage range. | Suitable for modern low-voltage digital systems only; not interoperable with 5 V buses or 24 V field wiring. | Select when system operates exclusively at 3.3 V and timing budget is tight; avoid if 5 V compatibility or industrial voltage margins are needed. |
| MC74HC03ADTR2G | TSSOP-14 package (4.4 mm × 5.0 mm), identical electrical specs and pinout; same die, different footprint. | Used where board space is constrained and fine-pitch reflow is supported; requires updated stencil and placement setup. | Choose for compact designs with automated SMT capability; no logic or performance trade-off versus NLV74HC03ADR2G. |
Compared with SN74LVC03APWR and MC74HC03ADTR2G, the NLV74HC03ADR2G uniquely balances wide supply range (2–6 V), industrial temperature rating, and SOIC-14 manufacturability - making it optimal for legacy upgrades, multi-rail interfaces, and cost-sensitive industrial controls where voltage flexibility and reliability outweigh ultra-high speed.

FAQ
What is the maximum sink current per output of the NLV74HC03ADR2G?
The NLV74HC03ADR2G specifies a maximum DC output sink current of ±25 mA per pin, measured at VCC = 6.0 V and TA = +25 °C. This value is validated across the full operating temperature range and supports direct LED driving and LSTTL load interfacing when used with appropriate external pullup resistors. The NLV74HC03ADR2G maintains this rating without derating up to +125 °C ambient.
Does the NLV74HC03ADR2G support wired-AND configurations?
Yes, the NLV74HC03ADR2G supports wired-AND configurations due to its open-drain outputs. Multiple NLV74HC03ADR2G outputs can be connected to a single pullup resistor to form a shared bus, where the logical AND of all outputs determines the bus state. This functionality is explicitly documented in Figure 6 of the onsemi datasheet and is commonly used for interrupt arbitration and bus signaling in mixed-voltage systems.
What is the operating temperature range of the NLV74HC03ADR2G?
The NLV74HC03ADR2G is rated for operation from −55 °C to +125 °C, meeting extended industrial and automotive under-hood requirements. This range is confirmed in the Recommended Operating Conditions table of the datasheet and applies to the standard part (non-Q suffix). The automotive-qualified variant NLV74HC03ADR2G−Q shares identical thermal specifications and adds AEC-Q100 qualification.
Can the NLV74HC03ADR2G interface directly with TTL logic inputs?
Yes, the NLV74HC03ADR2G can interface directly with TTL logic inputs when used with a suitable pullup resistor. Its outputs are compatible with LSTTL loads (up to 10 units), and its inputs accept LSTTL voltage levels when pulled up externally. This dual compatibility is explicitly stated in the datasheet's "Features" section and verified by VIH/VIL thresholds that meet TTL logic thresholds across the full 2.0–6.0 V supply range.
Is the NLV74HC03ADR2G RoHS compliant and lead-free?
Yes, the NLV74HC03ADR2G is RoHS compliant and lead-free, as indicated by the "G" suffix in its part number and confirmed in the "Ordering Information" and "Features" sections of the onsemi datasheet. It meets JEDEC Std. No. 7A, contains no intentionally added lead, brominated flame retardants, or halogens, and is certified Pb-free per J-STD-609.
