Product details
Overview
74LVX02MTCX 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 4.5 ns typical propagation delay at 3.3 V with 15 pF load in industrial temperature range (−40°C to +85°C).
For engineers reviewing the 74LVX02MTCX datasheet, pinout, applications, or equivalent options, key selection considerations include its 5 V-tolerant inputs, guaranteed simultaneous switching noise performance, TSSOP-14 WB package compatibility, and suitability for mixed-voltage digital control and interface circuits.
Technical Context
The 74LVX02MTCX implements four independent CMOS NOR gates with rail-to-rail input voltage tolerance (−0.5 V to +6.5 V), enabling direct interfacing of legacy 5 V logic outputs to 3.3 V system inputs without external level shifters. Its design ensures stable dynamic threshold behavior and controlled output skew (≤1.5 ns) across all four gates under varying capacitive loads.
It supports low-noise operation via guaranteed simultaneous switching noise limits and meets Pb-free, halogen-free, and RoHS compliance requirements. The device is characterized for DC and AC performance across −40°C to +85°C, with quiescent ICC ≤20 µA at 3.6 V and dynamic power dissipation modeled using CPD = 15 pF.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC02APWRE4 | 3.3 V only supply (1.65–3.6 V); inputs tolerant to 5.5 V (not 6.5 V); slightly faster (3.5 ns typ. @ 3.3 V) | Lacks full 5 V system interoperability; unsuitable where 5 V inputs exceed 5.5 V (e.g., TTL-compatible sources) | Select when operating exclusively in 3.3 V domains with strict speed requirements and no legacy 5 V interface needs |
| 74AHC02PW,118 | Wider supply range (2.0–5.5 V); inputs not 5 V tolerant (max VI = VCC + 0.5 V); higher ICC (100 µA max) | Requires matched supply voltages across connected logic families; incompatible with mixed 5 V/3.3 V signal routing | Prefer when full 5 V operation is required and all connected logic runs at same VCC |
Compared with SN74LVC02APWRE4 and 74AHC02PW,118, the 74LVX02MTCX uniquely supports 5 V input tolerance while operating from 3.3 V supply - making it the only option among the three for bridging legacy 5 V logic into modern low-voltage systems without redesigning interface circuitry.

FAQ
What is the maximum input voltage the 74LVX02MTCX can safely accept?
The 74LVX02MTCX accepts input voltages up to 6.5 V regardless of VCC level, enabling direct connection to 5 V TTL or CMOS outputs without risk of damage or latch-up. This rating is specified under DC conditions and applies across the full operating temperature range (−40°C to +85°C). The 74LVX02MTCX maintains functional integrity even when driven by 5 V signals while powered from a 3.3 V supply.
Does the 74LVX02MTCX support operation at 2.5 V supply?
Yes, the 74LVX02MTCX is fully specified for operation at 2.5 V supply, falling within its recommended 2.0 V to 3.6 V range. At 2.5 V, it delivers VIH = 1.7 V min and VIL = 0.8 V max, with tPLH/tPHL ≤13.5 ns (CL = 15 pF, TA = −40°C to +85°C). The 74LVX02MTCX retains 5 V input tolerance and guaranteed noise immunity at this voltage, making it suitable for low-power battery-operated systems.
Can unused inputs on the 74LVX02MTCX be left floating?
No - unused inputs on the 74LVX02MTCX must be tied HIGH or LOW; floating inputs are prohibited per datasheet Note 1. Uncontrolled input states cause increased ICC, unpredictable output behavior, and potential oscillation due to intermediate voltage levels triggering both PMOS and NMOS transistors. For the 74LVX02MTCX, tie unused An/Bn pins to VCC or GND via ≤10 kΩ resistors to ensure stable logic states and minimize power consumption.
What is the thermal performance of the 74LVX02MTCX in TSSOP-14 WB package?
The 74LVX02MTCX in TSSOP-14 WB (Case 948G) has a maximum junction-to-ambient thermal resistance (θJA) of 120°C/W under standard JEDEC PCB conditions. At 833 mW maximum power dissipation, this yields a worst-case ΔTJ = 100°C above ambient - well within its −40°C to +85°C operating range when ambient stays below 60°C. The 74LVX02MTCX requires no heatsink for typical logic-level loading but benefits from copper pour under the exposed pad if present (though this package lacks an exposed thermal pad).
Is the 74LVX02MTCX pin-compatible with other 74-series NOR gate variants?
The 74LVX02MTCX follows the standard 14-pin DIP/TSSOP pinout for quad 2-input NOR gates (e.g., 74HC02, 74LS02), with identical pin assignments for VCC (14), GND (7), and all inputs/outputs. However, electrical differences - especially 5 V input tolerance and lower VCC range - mean it is not a drop-in replacement without verifying system-level voltage compatibility. The 74LVX02MTCX shares pinout but not full functional equivalence with non-LVX variants.
