Product details
Overview
MC74LVX02DR2 from onsemi is a quad 2-input NOR gate IC designed for level-shifting logic interfacing between 3.0 V and 5.0 V systems. It features 5 V-tolerant inputs (up to 6.5 V), 4.5 ns typical propagation delay at VCC = 3.3 V, ±25 mA output drive, and operates across −40°C to +85°C. It is used in mixed-voltage digital control subsystems such as industrial PLC I/O modules.
For engineers reviewing the MC74LVX02DR2 datasheet, pinout, applications, or equivalent options, key selection considerations include input voltage tolerance, propagation delay matching across gates, output drive capability under 3.3 V supply, and SOIC-14 NB package compatibility with legacy 0.150" wide footprints.
Technical Context
The MC74LVX02DR2 implements four independent CMOS NOR gates in a single SOIC-14 NB package, each with symmetrical input structure enabling bidirectional 3.3 V/5 V interface. Its 5 V-tolerant inputs use clamped protection diodes without internal pull-ups, allowing direct connection to 5 V buses while powered from 3.3 V.
Propagation delays are balanced across all four gates (tPLH/tPHL skew ≤1.5 ns), and dynamic noise parameters-VOLP ≤0.5 V and VIHD ≥2.0 V-are specified under 3.3 V operation with 50 pF load, supporting clean signal integrity in noise-sensitive control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - Enables operation in modern low-voltage digital systems while maintaining compatibility with 3.3 V rails. |
| Input Voltage Tolerance | −0.5 V to +6.5 V - Allows safe interfacing with 5 V logic without external level shifters or resistive dividers. |
| tPD (Typ) | 4.5 ns at VCC = 3.3 V, CL = 15 pF - Supports >100 MHz toggle rates in synchronous control paths. |
| IOUT (Max) | ±25 mA per output - Drives standard TTL loads or multiple 74LVC inputs without buffering. |
| VIH/VIL Thresholds | VIH = 2.4 V (min), VIL = 0.8 V (max) at VCC = 3.6 V - Ensures robust noise margin (>0.7 V) against ground bounce in industrial environments. |
| ICC (Max) | 20 µA at TA = −40°C to +85°C - Enables low-quiescent-power operation in always-on monitoring circuits. |
| ESD Rating | HBM > 2000 V - Provides built-in handling robustness during board assembly and field service. |
Pinout & Package
MC74LVX02DR2 uses the SOIC-14 NB (Case 751A) package: 14-pin, 0.150" wide body, 1.27 mm pitch, Pb-free, RoHS compliant. Pin 1 is top-left corner with notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Outputs (O0–O3) | Active-low NOR outputs; each capable of sourcing/sinking ±25 mA into standard logic loads. |
| 2, 3, 5, 6, 8, 9, 11, 12 | Inputs (A0/B0–A3/B3) | 5 V-tolerant CMOS inputs; accept 0–6.5 V signals regardless of VCC setting. |
| 7 | GND | Ground reference for all logic thresholds and output drivers; must be low-impedance for noise control. |
| 14 | VCC | Primary power supply (2.0–3.6 V); powers internal logic and output stages; bypassing required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant inputs | Enables direct connection to legacy 5 V microcontrollers or sensors without external level translation circuitry. |
| Balanced propagation delays | Ensures deterministic timing across all four NOR gates-critical for synchronous enable/disable sequencing in motor control logic. |
| Low dynamic noise (VOLP ≤ 0.5 V) | Reduces crosstalk risk in dense PCB layouts where multiple MC74LVX02DR2 devices share supply or ground planes. |
| Power-down input protection | Prevents back-driving current flow when VCC = 0 V, protecting upstream drivers during hot-swap or partial-power-down scenarios. |
| Latch-up immunity > 300 mA | Guarantees robust operation under transient overvoltage or ESD events without destructive latch-up. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC02APWR | Lower VCC range (1.65–3.6 V); no 5 V input tolerance; 3.7 ns tPD (typ) at 3.3 V. | Requires external clamping for 5 V inputs; suited for pure 3.3 V systems only. | Select when cost sensitivity outweighs mixed-voltage interface needs and layout space permits clamping diodes. |
| 74AUP1G02GW,125 | Single-gate variant in SC-70; VCC = 0.8–3.6 V; 6.0 ns tPD (typ); 5 V-tolerant inputs supported. | Requires four separate packages for quad functionality; higher assembly cost and board area. | Choose for ultra-low-power designs (<0.5 µA ICC) where gate-level modularity justifies footprint and sourcing overhead. |
Compared with SN74LVC02APWR and 74AUP1G02GW,125, the MC74LVX02DR2 uniquely delivers quad-gate integration, guaranteed 5 V input tolerance, and sub-7 ns propagation delay in a standard SOIC-14 footprint-making it optimal for retrofitting legacy 5 V systems with modern low-voltage controllers.

FAQ
What is the maximum input voltage rating for MC74LVX02DR2?
The MC74LVX02DR2 supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This 5 V-tolerant feature allows direct connection to 5 V buses while operating from a 3.3 V supply, eliminating external level-shifting components. The specification is validated across the full temperature range (−40°C to +85°C) and is not dependent on output loading conditions.
Does MC74LVX02DR2 support mixed-voltage operation in both directions?
Yes, the MC74LVX02DR2 enables bidirectional interfacing: its inputs accept up to 6.5 V regardless of VCC (2.0–3.6 V), and its outputs swing rail-to-rail within the VCC range. When VCC = 3.3 V, outputs drive to ≈0 V and ≈3.3 V, while inputs safely receive 5 V logic levels-making it ideal for bridging legacy 5 V peripherals to modern 3.3 V controllers.
What is the guaranteed propagation delay variation between gates in MC74LVX02DR2?
The MC74LVX02DR2 guarantees output-to-output skew (tOSHL/tOSLH) ≤1.5 ns under VCC = 3.3 V and CL = 50 pF, measured across any two outputs switching in the same direction. This tight matching ensures deterministic timing in applications like parallel enable generation or synchronized reset distribution, where gate-to-gate delay mismatch could cause race conditions.
Can MC74LVX02DR2 be used with VCC = 2.5 V?
Yes, MC74LVX02DR2 is fully specified for VCC = 2.0 V to 3.6 V. At 2.5 V, VIH is guaranteed ≥1.7 V and VIL ≤0.8 V, providing >0.9 V noise margin. Propagation delay increases to 7.0 ns (typ) at CL = 15 pF, and output drive remains ±25 mA-supporting reliable operation in battery-powered or low-power industrial nodes.
Is MC74LVX02DR2 pin-compatible with standard 74-series NOR gates?
The MC74LVX02DR2 is functionally and pin-compatible with industry-standard quad 2-input NOR gates in SOIC-14 packages-including the 74HC02 and 74HCT02-but differs in key electrical behavior: it lacks HCT's TTL-compatible inputs and instead offers 5 V-tolerant CMOS inputs. Its pinout matches the standard 14-pin NOR gate layout (GND at pin 7, VCC at pin 14), enabling drop-in replacement where voltage tolerance is required.
