Product details
Overview
74LVX02MX from onsemi is a low-voltage quad 2-input NOR gate IC designed for level-translating logic interfaces between 5 V and 3.3 V systems. It operates from 2.0 V to 3.6 V, tolerates input voltages up to 6.5 V, delivers ±25 mA output drive, and features guaranteed simultaneous switching noise performance for stable operation in mixed-voltage digital systems.
For engineers reviewing the 74LVX02MX datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.5 V-tolerant inputs, TSSOP-14 WB package, propagation delay under 8.0 ns at 3.3 V/50 pF, dynamic noise immunity, and RoHS-compliant Pb-free construction.
Technical Context
The 74LVX02MX implements four independent 2-input NOR gates in a single monolithic CMOS device. Its input structure supports voltage-level translation-accepting 0–5.5 V inputs while operating from a 2.0–3.6 V supply-enabling direct interfacing of legacy 5 V logic with modern 3.3 V microcontrollers and FPGAs without external level shifters.
It guarantees simultaneous switching noise (SSN) limits and dynamic threshold behavior across temperature (−40 °C to +85 °C), with propagation delays specified down to 4.5 ns (typ.) at 3.3 V/15 pF and output skew ≤1.5 ns between gates-critical for timing-critical control logic and synchronous state machines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - Enables operation in standard 3.3 V systems with margin for supply variation. |
| Input Voltage Tolerance | Up to 6.5 V - Allows safe connection to 5 V outputs without clamping diodes or external protection. |
| Propagation Delay | ≤8.0 ns max at 3.3 V/50 pF - Supports >100 MHz toggle rates in combinatorial logic paths. |
| Output Drive | ±25 mA - Sufficient to drive multiple 74LVC inputs or small capacitive loads directly. |
| Dynamic Noise Immunity | VOLP ≤0.5 V, VIHD ≥2.0 V at 3.3 V - Ensures reliable switching under fast edge-induced crosstalk. |
| Quiescent ICC | ≤20 µA max at 3.6 V - Supports ultra-low-power standby modes in battery-backed logic. |
| Operating Temperature | −40 °C to +85 °C - Qualified for industrial-grade embedded control and automotive body electronics. |
Pinout & Package
TSSOP-14 WB (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm profile, 0.65 mm pitch, Pb-free, halogen-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | A0/B0, A1/B1, A2/B2, A3/B3 | Four independent NOR gate inputs - each pair drives one gate; unused inputs must be tied HIGH or LOW. |
| 3, 6, 10, 13 | O0, O1, O2, O3 | Respective NOR gate outputs - push-pull CMOS, rail-to-rail swing within VCC/GND. |
| 7 | GND | Digital ground reference - decoupling capacitor required near pin for noise suppression. |
| 14 | VCC | Primary power supply - must be bypassed with 0.1 µF ceramic capacitor close to pin. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC02APWR | 3.3 V only; inputs not 5 V tolerant (max VI = VCC + 0.5 V); faster tPLH (3.5 ns typ. @ 3.3 V/50 pF) | Requires external level shifting for 5 V inputs; better suited for pure 3.3 V domains with speed priority. | Select when system uses only 3.3 V signaling and needs lower propagation delay; avoid if interfacing 5 V sources. |
| 74LCX02MTCX | Same 74LVX family architecture but higher ICC (max 50 µA); identical 6.5 V input tolerance and TSSOP-14 WB package | Higher quiescent current limits use in ultra-low-power battery systems; otherwise drop-in compatible in footprint and logic function. | Acceptable functional substitute where 74LVX02MX supply current headroom is sufficient; verify thermal budget in high-density layouts. |
Compared with SN74LVC02APWR and 74LCX02MTCX, the 74LVX02MX uniquely balances 5 V input tolerance, industrial temperature range, and sub-20 µA quiescent current-making it optimal for mixed-voltage industrial control where reliability and power efficiency coexist.

FAQ
What is the maximum input voltage the 74LVX02MX can safely accept?
The 74LVX02MX accepts DC input voltages up to 6.5 V regardless of VCC level-this allows direct connection to 5 V logic outputs without damage or level-shifting circuitry. This specification is guaranteed across the full operating temperature range (−40 °C to +85 °C) and is validated per the Absolute Maximum Ratings table in the official onsemi datasheet for 74LVX02MX.
Does the 74LVX02MX support operation at 2.5 V supply?
Yes, the 74LVX02MX is fully specified for operation at 2.5 V: the Recommended Operating Conditions table confirms VCC min = 2.0 V, and DC electrical characteristics-including VIH, VOL, and propagation delay-are guaranteed at 2.5 V. At this voltage, typical propagation delay is ~7.5 ns (CL = 50 pF), making it suitable for low-power 2.5 V system designs.
Is the 74LVX02MX pin-compatible with standard 74HC02 or 74LS02 devices?
No, the 74LVX02MX is not pin-compatible with 74HC02 or 74LS02. While all are quad 2-input NOR gates, the 74LVX02MX uses a 14-pin TSSOP-14 WB package with specific pin assignments (e.g., VCC on pin 14, GND on pin 7), whereas 74HC02 typically uses SOIC-14 or PDIP-14 with different pinouts. Always verify layout compatibility using the 74LVX02MX connection diagram-not generic logic family assumptions.
What is the recommended decoupling for the 74LVX02MX?
A 0.1 µF ceramic capacitor placed as close as possible to the VCC (pin 14) and GND (pin 7) pins is mandatory for stable operation. The 74LVX02MX exhibits measurable simultaneous switching noise; insufficient local decoupling causes output instability and increased VOLP. For multi-gate boards, add a bulk 4.7 µF tantalum or aluminum electrolytic capacitor per power rail segment.
Can unused inputs on the 74LVX02MX be left floating?
No-unused inputs on the 74LVX02MX must never be left floating. Per the datasheet Note 1, all unused inputs must be tied HIGH (to VCC) or LOW (to GND) to prevent undefined logic states, increased ICC, and potential oscillation. Floating inputs increase susceptibility to noise and may cause excessive current draw due to partial transistor turn-on in the input stage.
