Product details
Overview
74VHC02MTR from STMicroelectronics is a quad 2-input NOR gate in high-speed CMOS technology, operating from 2V to 5.5V supply, with typical propagation delay of 3.6ns at 5V, ±8mA symmetrical output drive, and input tolerance up to 7V independent of VCC. It enables level-shifting between 5V and 3V logic domains in digital control subsystems.
For engineers reviewing the 74VHC02MTR datasheet, 74VHC02MTR pinout, 74VHC02MTR application, or 74VHC02MTR equivalent, key selection criteria include input overvoltage tolerance (0–7V), power-down input protection, ESD immunity (2kV HBM), balanced tPLH/tPHL delay matching, and SOP-14 package compatibility with legacy 74-series footprints.
Technical Context
The device implements four independent NOR gates using sub-micron C2MOS process with three-stage buffered output architecture, delivering high noise immunity (VNIH/VNIL ≥ 28% VCC) and low dynamic noise (VOLP ≤ 0.8V). Input structures support hot-swap and partial-power-down operation without damage.
All inputs accept DC voltages from –0.5V to +7.0V regardless of VCC state, enabling safe interfacing across mixed-supply systems. Outputs provide symmetrical sourcing/sinking capability (|IOH| = IOL ≥ 8mA) and latch-up immunity per JEDEC JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 5.5V - supports dual-rail 3.3V/5V system integration without level shifters |
| tPD (Typ.) | 3.6ns at VCC = 5V, CL = 15pF - enables >100MHz toggle rates in combinatorial logic paths |
| IOH / IOL | ≥ 8mA - drives standard TTL loads and multiple CMOS inputs directly |
| VI (Max) | 7.0V - allows safe input operation during power sequencing or fault conditions |
| ICC (Max) | 2µA at TA = 25°C - enables ultra-low static power in battery-backed or standby circuits |
| ESD Rating | 2kV HBM - meets IEC 61000-4-2 Level 2 for board-level robustness |
| VNIH / VNIL | ≥ 28% VCC - ensures reliable logic recognition under noisy supply or ground bounce |
Pinout & Package
74VHC02MTR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package, also referred to as SOP-14, with 1.27mm pitch and tape-and-reel delivery (MTR suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y - Gate Outputs | Active-low NOR outputs with symmetrical drive strength and hot-swap-safe clamping |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A - Input A | NOR gate first inputs; tolerate –0.5V to +7V, protected against ESD and overvoltage |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B - Input B | NOR gate second inputs; identical electrical specs and protection as Input A pins |
| 7 | GND | Ground reference for all internal circuitry and I/O; decoupling capacitor connection point |
| 14 | VCC | Positive supply rail (2–5.5V); powers all four gates and internal buffers |
Key Features
| Feature | Design Value |
|---|---|
| Input Overvoltage Tolerance | 0–7V independent of VCC - eliminates need for external clamping diodes in mixed-voltage interfaces |
| Power-Down Input Protection | Inputs remain functional and non-damaging even when VCC = 0V - supports live insertion and partial system shutdown |
| Symmetrical Output Drive | |IOH| = IOL ≥ 8mA - ensures matched rise/fall times and reduces signal skew in timing-critical paths |
| Low Dynamic Noise | VOLP ≤ 0.8V at VCC = 5V, CL = 50pF - minimizes crosstalk and ground bounce in dense PCB layouts |
| High Noise Immunity | VNIH/VNIL ≥ 28% VCC - maintains logic integrity in electrically noisy industrial or automotive environments |

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 |
|---|---|---|---|
| SN74VHC02DR | TI-manufactured; identical AC/DC specs but slightly higher max ICC (4µA vs. 2µA) | Same SOP-14 footprint; validated for TI-specific reference designs in motor control gate drivers | Preferred where TI ecosystem toolchain (e.g., WEBENCH) integration is required |
| MC74VHC02DT | ON Semiconductor version; same pinout but wider operating temperature range (–55°C to +125°C vs. –40°C to +125°C) | Used in extended-temp industrial sensors; requires revalidation of thermal derating in high-ambient designs | Recommended for aerospace or downhole equipment where full military-grade temp range is mandatory |
Compared with SN74VHC02DR and MC74VHC02DT, the 74VHC02MTR offers the lowest quiescent current and strongest input overvoltage margin, making it optimal for power-sensitive and mixed-voltage interface applications where ST's C2MOS process advantages are leveraged.

FAQ
Can 74VHC02MTR be used with a 3.3V supply while interfacing to 5V peripherals?
Yes. The device operates from 2V to 5.5V and accepts input voltages up to 7V regardless of VCC. When powered at 3.3V, its outputs swing rail-to-rail (0V to 3.3V), and its 5V-tolerant inputs allow direct connection to 5V peripherals without level shifters or resistive dividers.
Does 74VHC02MTR require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs may be tied directly to VCC or GND. The device features built-in power-down protection and high-impedance inputs with negligible leakage (±1µA max), eliminating risk of floating nodes or unintended switching in unconnected configurations.
What is the maximum capacitive load this device can drive reliably?
The 74VHC02MTR is characterized up to 50pF load capacitance in AC specs, with tPLH/tPHL specified at 15pF and 50pF. For loads exceeding 50pF, propagation delay increases linearly; design margin should include 20% derating for timing-critical paths, especially above 10MHz toggle rates.
Is the SOP-14 package of 74VHC02MTR compatible with automated optical inspection (AOI) and reflow soldering?
Yes. The SOIC-14 package conforms to JEDEC MS-012 standards, with gull-wing leads and defined coplanarity (≤0.10mm), supporting standard AOI algorithms and lead-free reflow profiles (peak 260°C, 60s max). ST provides recommended stencil aperture and solder paste volume data in AN2827.
