Product details
Overview
NLV74HC02ADR2G from onsemi is a quad 2-input NOR gate IC in SOIC-14 package, operating across 2.0–6.0 V supply, delivering 10 LSTTL load drive capability and supporting −55 °C to +125 °C industrial temperature range - used in digital logic control, reset generation, and enable/disable signal conditioning in embedded power management systems.
For engineers reviewing the NLV74HC02ADR2G datasheet, pinout, applications, or equivalent options, this page provides verified pin functions, real-world timing specs (e.g., 13 ns max propagation delay at 6.0 V), JEDEC-compliant noise immunity, and direct alternatives for automotive-grade logic replacement.
Technical Context
The NLV74HC02ADR2G implements four independent CMOS NOR gates with high-noise-immunity inputs compatible with both standard CMOS and LSTTL outputs (with pullup resistors). Its silicon-gate architecture ensures low static current (≤1.0 µA) and rail-to-rail output swing.
It operates under JEDEC Std. No. 7.0A compliance, supports AEC-Q100 qualification (via −Q suffix variants), and features 40 FETs per device (10 equivalent gates) - enabling deterministic combinational logic synthesis without external level-shifting in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - each gate performs Y = NOT(A OR B); enables compact implementation of active-low enable, reset, or inhibit logic. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5.0 V microcontrollers, battery-powered sensors, and legacy TTL systems. |
| Propagation Delay (tPLH/tPHL) | 13 ns max at VCC = 6.0 V - ensures sub-20 ns timing margin for 25 MHz synchronous control loops. |
| Output Drive | ±25 mA DC per pin - drives 10 LSTTL loads directly; eliminates need for buffer stages in fanout-critical nodes. |
| Input Leakage Current | ±1.0 µA max at VCC = 6.0 V - enables reliable operation with high-impedance pullups/pulldowns and low-power wake-up detection. |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor IoT edge nodes. |
| ESD Rating | Human Body Model > 2000 V - withstands handling in non-EPA environments without additional protection circuitry. |
Pinout & Package
Package: SOIC-14 (Case 751A), Pb-free, RoHS compliant, moisture sensitivity level 1. Dimensions: 8.75 mm × 3.90 mm × 1.75 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Input A of Gate 1–4 | Active-high logic input; accepts 0–VCC voltage; requires tie-to-rail if unused (per datasheet Note 3). |
| 2, 6, 10, 12 | Input B of Gate 1–4 | Second active-high input per gate; identical electrical behavior to Pin A terminals. |
| 3, 4, 8, 11 | Output Y of Gate 1–4 | CMOS push-pull output; rail-to-rail swing; capable of sourcing/sinking ±25 mA. |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance connection. |
| 14 | VCC | Positive supply rail; bypass capacitor (0.1 µF) recommended within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| High noise immunity | CMOS input threshold ratios (VIH/VIL) maintained across full VCC and temperature range - rejects >400 mV noise spikes in industrial EMI environments. |
| LSTTL/CMOS interoperability | Inputs accept LSTTL logic levels when pulled up; outputs directly drive CMOS, NMOS, and TTL loads - eliminates level translators in mixed-technology boards. |
| Low quiescent current | ICC ≤ 10 µA at VCC = 6.0 V and TA = 25 °C - reduces standby power in always-on sensor nodes and battery-backed controllers. |
| JEDEC Std. 7.0A compliance | Meets standardized AC/DC parametric limits for high-speed CMOS - simplifies qualification for aerospace and medical subsystems requiring traceable standards alignment. |
| Pb-free & RoHS | Halogen-free construction with "G" suffix marking - satisfies EU RoHS Directive 2011/65/EU and IPC-1752A material declaration requirements. |
Applications
| Industrial Motor Control | Automotive Body Controller |

Use Value: Low input leakage (≤1.0 µA) prevents unintended enable state drift during long-term storage or brownout conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC02DR | Same logic function, SOIC-14, but rated only to +85 °C ambient; no AEC-Q100 qualification. | Suitable for commercial-grade consumer electronics; not approved for automotive under-hood use. | Select when cost is prioritized over extended temperature or automotive qualification. |
| MC74HC02ADTR2G | TSSOP-14 package (4.5 mm × 5.1 mm), identical electrical specs and −55 °C to +125 °C rating. | Enables higher board density in space-constrained designs; requires rework of PCB footprint and solder profile. | Select when miniaturization outweighs SOIC-14 layout reuse; same die, different package. |
Compared with SN74HC02DR and MC74HC02ADTR2G, the NLV74HC02ADR2G uniquely combines automotive-grade temperature range, SOIC-14 compatibility, and onsemi's validated AEC-Q100 process - making it the preferred choice where drop-in replacement in legacy industrial layouts is required alongside extended thermal robustness.

FAQ
What is the maximum operating temperature for NLV74HC02ADR2G?
The NLV74HC02ADR2G is rated for operation from −55 °C to +125 °C ambient temperature. This extended range is validated per JEDEC standards and aligns with AEC-Q100 Grade 1 requirements, making NLV74HC02ADR2G suitable for under-hood automotive and high-temperature industrial deployments where standard HC devices (e.g., SN74HC02DR) would fail.
Does NLV74HC02ADR2G require external pull-up resistors on inputs?
NLV74HC02ADR2G inputs are CMOS-compatible and do not require pull-ups for standard CMOS driving. However, when interfacing with LSTTL outputs, external pull-up resistors (typically 4.7 kΩ to VCC) are needed to ensure VIH exceeds minimum thresholds - as specified in the NLV74HC02ADR2G datasheet Figure 1 and Recommended Operating Conditions table.
Can NLV74HC02ADR2G drive LEDs directly?
Yes - each output of NLV74HC02ADR2G can sink or source up to ±25 mA, sufficient to drive standard 2 mA–20 mA indicator LEDs. For a typical red LED (2.0 V VF, 10 mA), use a 330 Ω series resistor with VCC = 5.0 V. Always verify VOL and VOH margins under load using NLV74HC02ADR2G's DC Electrical Characteristics table.
Is NLV74HC02ADR2G pin-compatible with older 74LS02 devices?
Yes - NLV74HC02ADR2G is explicitly designed as a pinout-identical replacement for 74LS02 in SOIC-14 packaging. The NLV74HC02ADR2G maintains identical pin assignments (e.g., Pin 1 = A1, Pin 2 = B1, Pin 3 = Y1, Pin 7 = GND, Pin 14 = VCC), enabling drop-in upgrades from bipolar LS logic to low-power, high-noise-immunity CMOS without PCB changes.
What is the meaning of the 'NLV' prefix in NLV74HC02ADR2G?
The 'NLV' prefix denotes onsemi's "Non-Standard Logic Voltage" series - indicating enhanced performance for extended temperature and automotive applications. In NLV74HC02ADR2G, this translates to guaranteed operation from −55 °C to +125 °C, tighter AC timing specs, and qualification to AEC-Q100 stress tests - distinguishing it from standard 74HC02A variants limited to commercial temperature ranges.
