Product details
Overview
74LVC1G02FX4-7 from Diodes Incorporated is a single 2-input positive NOR gate in a 6-pin X2-DFN1409-6 chip-scale package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and IOFF partial-power-down protection. It delivers ±24mA output drive at 3.3V and supports voltage-level shifting in mixed-voltage digital interfaces such as I²C buffer stages or reset signal conditioning.
For engineers reviewing the 74LVC1G02FX4-7 datasheet, 74LVC1G02FX4-7 pinout, 74LVC1G02FX4-7 application, or 74LVC1G02FX4-7 equivalent, key selection criteria include input voltage tolerance (5.5V), IOFF-enabled power-down isolation, propagation delay ≤6.0ns at 3.3V, ±24mA drive strength, and thermal resistance (θJA = 470°C/W) for compact PCB layouts.
Technical Context
This NOR gate implements the Boolean function Y = A + B (positive logic), with push-pull CMOS output stage and rail-to-rail input voltage range (–0.5V to 6.5V). Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe use in hot-swap or multi-rail systems.
It operates across –40°C to +125°C ambient temperature, supports TTL-level interfacing, and features ESD robustness exceeding 2000V HBM and 1000V CDM. Input transition rate is specified up to 20 ns/V at 1.8V, ensuring reliable timing in high-speed control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables direct interface between 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - Allows connection to higher-voltage buses while powered from lower VCC, critical for mixed-supply isolation. |
| IOFF Leakage Current | ±200 μA max at 125°C - Ensures negligible current flow during partial power-down, preventing bus contention or damage. |
| Propagation Delay | ≤6.0 ns at 3.3V, 25°C - Supports >100 MHz toggle rates in timing-critical control paths like enable/disable sequencing. |
| Output Drive Strength | ±24 mA at 3.3V - Sufficient to drive multiple LVC inputs or small capacitive loads (<30 pF) without external buffering. |
| ESD Protection | 2000V HBM, 1000V CDM - Meets industrial-grade robustness requirements for board-level handling and system integration. |
| Operating Temperature | –40°C to +125°C - Qualified for extended-temperature industrial and automotive under-hood applications. |
Pinout & Package
X2-DFN1409-6 is a 1.4 mm × 0.9 mm × 0.4 mm chip-scale package with 0.5 mm pad pitch and bottom-side thermal pad. Pin 1 (A) is marked by a circular fiducial; pins are arranged in a 3×2 staggered layout with no exposed leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | Primary logic input; accepts voltages up to 5.5V regardless of VCC, enabling level translation. |
| B | Data Input | Secondary logic input; electrically identical to A, supporting dual-input NOR functionality. |
| GND | Ground Reference | Return path for all internal currents; must be low-impedance to ensure noise immunity and stable switching thresholds. |
| VCC | Power Supply | Supplies core logic and output stage; decoupling capacitor (0.1 µF) required within 2 mm for stable operation. |
| Y | Data Output | Push-pull CMOS output; sinks or sources up to ±24 mA; compatible with LVC, LV, and TTL load standards. |
| NC | No Connection | Internally unconnected terminal; must remain floating or tied to GND per layout guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial-Power-Down Support | Disables output during VCC=0V, eliminating backfeed current into powered rails-essential for hot-plug and multi-voltage domain isolation. |
| 5.5V-Tolerant Inputs | Accepts 5V signals while operating from 1.65V–3.3V supplies, enabling seamless interfacing between legacy and low-voltage logic without external translators. |
| Low Dynamic Power Consumption | Typical ICC = 0.1 µA at 3.3V/25°C - minimizes quiescent current in battery-powered or always-on subsystems. |
| High-Drive Output Stage | ±24 mA at 3.3V - drives ≥10 LVC loads or 30 pF capacitance directly, reducing need for buffer stages in fanout-constrained designs. |
| Industrial Temperature Range | –40°C to +125°C operation - qualified for deployment in harsh environments including motor control, industrial PLCs, and automotive body electronics. |
Applications
| Power Sequencing Control | Reset Signal Conditioning |
|---|---|
|
Use Scenario: Coordinating startup order of multiple voltage rails in FPGA or SoC power management. IC Role / Device Role / Timing Role: NOR gate combines delayed enable signals to generate synchronized power-good assertions. Use Value: IOFF prevents reverse current when auxiliary rails power down before main supply, avoiding latch-up or data corruption. |
Use Scenario: Debouncing and synchronizing manual or watchdog-generated reset pulses in embedded microcontrollers. IC Role / Device Role / Timing Role: Acts as active-low reset combiner, merging POR, WDT, and user-reset inputs into a single clean reset line. Use Value: 5.5V-tolerant inputs accept direct connection to 5V reset sources while MCU runs at 3.3V, eliminating discrete resistors or translators. |
| I²C Bus Level Translation | Hot-Swap Signal Isolation |
|
Use Scenario: Bridging 3.3V master and 5V slave devices on shared I²C lines without dedicated level shifters. IC Role / Device Role / Timing Role: Configured as open-drain-compatible NOR (with pull-up) to translate SDA/SCL logic levels bidirectionally. Use Value: Propagation delay ≤6.0 ns at 3.3V ensures compatibility with standard-mode (100 kHz) and fast-mode (400 kHz) I²C timing budgets. |
Use Scenario: Isolating control signals (e.g., enable, fault) between hot-pluggable modules and host backplane. IC Role / Device Role / Timing Role: Provides fail-safe signal blocking during insertion/removal by leveraging IOFF to disconnect outputs when module VCC is absent. Use Value: Prevents back-driving of host logic during hot-swap events, eliminating risk of bus contention or supply rail collapse. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Same logic function and IOFF, but in SOT-23-5 (5-pin) package with different pinout (no NC pin); θJA = 204°C/W. | Larger footprint and higher thermal performance; lacks chip-scale size advantage for ultra-dense layouts. | Select when board space allows larger package and lower thermal resistance is prioritized over miniaturization. |
| 74AUP1G02GW,125 | Lower static current (0.9 µA typical), wider VCC range (0.8V–3.6V), but no 5.5V input tolerance or IOFF. | Not suitable for mixed-voltage or partial-power-down systems; limited to single-supply sub-3.6V domains. | Choose only for ultra-low-power battery applications where voltage translation and power-down isolation are unnecessary. |
Compared with SN74LVC1G02DBVR and 74AUP1G02GW,125, the 74LVC1G02FX4-7 uniquely balances chip-scale packaging, 5.5V input tolerance, and IOFF-making it optimal for space-constrained, multi-rail, and hot-swap-capable designs where other alternatives compromise on at least one of these attributes.

FAQ
Can 74LVC1G02FX4-7 operate with VCC = 1.5V?
No. The device is specified for 1.65V to 5.5V operation. At 1.5V, input thresholds and output drive fall outside guaranteed specifications, risking metastability or failure to switch. Data retention is supported down to 1.5V, but functional operation requires minimum 1.65V.
Is the NC pin on 74LVC1G02FX4-7 required to be grounded?
No. The NC pin is internally unconnected and must remain floating or be left unpopulated. Grounding it may introduce parasitic capacitance or leakage paths; Diodes' recommended layout shows it unconnected in all reference footprints.
What is the maximum capacitive load this NOR gate can drive reliably?
At 3.3V and 25°C, the device maintains ≤6.0 ns propagation delay driving ≤30 pF (per datasheet test condition). For loads exceeding 30 pF, output rise/fall times increase, potentially violating setup/hold margins-external buffering is recommended above 50 pF.
Does 74LVC1G02FX4-7 meet AEC-Q100 for automotive use?
Standard 74LVC1G02FX4-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., 74LVC1G02W5Q-7) with PPAP documentation, IATF 16949 manufacturing, and extended qualification testing-contact Diodes or Aetrix for Q-grade availability.
