Product details
Overview
74LVC1G02QW5-7 from Diodes Incorporated is an AEC-Q100 Grade 1 qualified single 2-input positive NOR gate in SOT25 package, operating from 1.65V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF-enabled partial power-down protection-used for voltage level shifting and signal isolation in automotive body control modules.
For engineers reviewing the 74LVC1G02QW5-7 datasheet, 74LVC1G02QW5-7 pinout, 74LVC1G02QW5-7 application, or 74LVC1G02QW5-7 equivalent, key selection criteria include automotive temperature range (-40°C to +125°C), mixed-voltage interface capability, IOFF leakage (<±2μA), propagation delay (≤6.0ns at 3.3V), and SOT25 thermal resistance (θJA = 184°C/W).
Technical Context
This NOR gate implements the Boolean function Y = A + B (positive logic) with push-pull CMOS output stage, supporting rail-to-rail input voltage up to 5.5V independent of VCC. Its IOFF circuit actively disables output during power-down to prevent back-current flow between powered and unpowered domains.
Designed for automotive Grade 1 operation, it meets AEC-Q100 stress tests including >2000V HBM ESD, >1000V CDM ESD, and >100mA latch-up immunity. Propagation delay varies from 1.7ns (5V) to 3.2ns (1.8V), with consistent 14pF power dissipation capacitance across supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive NOR (Y = A + B) |
| Supply Voltage Range | 1.65V to 5.5V - enables direct interfacing with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage signals without level shifters |
| IOFF Leakage Current | ±2 μA max - ensures <1μA backflow during partial power-down, protecting downstream circuits |
| Output Drive Strength | ±24 mA at 3.3V - sufficient to drive multiple LVC loads or moderate capacitive loads (≤30pF) |
| Propagation Delay | 2.1 ns typical at 3.3V - supports >100 MHz toggle rates in clean signal paths |
| Operating Temperature | -40°C to +125°C ambient - certified for engine bay, transmission, and ADAS ECU placement |
Pinout & Package
SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with moisture sensitivity level 1 (J-STD-020), matte tin-plated leads, and thermal resistance θJA = 184°C/W on standard FR-4 board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Primary logic input; accepts 0–5.5V regardless of VCC; internally clamped |
| 2 (B) | Data Input | Secondary logic input; identical electrical behavior to Pin 1 |
| 3 (GND) | Ground Reference | Return path for all internal currents; must be low-impedance for noise immunity |
| 4 (Y) | Data Output | CMOS push-pull output; drives high/low actively; supports IOFF state when VCC = 0 |
| 5 (VCC) | Supply Voltage | Power rail for internal logic; IOFF activation requires VCC = 0V or floating |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for -40°C to +125°C operation with full stress testing (HBM >2kV, CDM >1kV, latch-up >100mA) |
| IOFF partial power-down support | Output automatically enters high-impedance state when VCC = 0V, blocking reverse current flow |
| 5.5V-tolerant inputs | Inputs remain functional and non-damaging even when driven by 5V signals while VCC = 1.8V |
| Low dynamic power consumption | Typical ICC = 0.1μA at 5.5V; CPD = 14pF - reduces system-level power budget in always-on nodes |
| Lead-free & green compliance | Fully RoHS 3 compliant (2015/863/EU); halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Automotive Body Control Unit (BCU) | Industrial PLC I/O Isolation |
|---|---|
|
Use Scenario: Isolating wake-up signals between low-power microcontroller sleep mode and always-on CAN transceiver. IC Role / Device Role / Timing Role: NOR gate configured as active-low OR to combine multiple interrupt sources into a single wake line. Use Value: IOFF prevents current injection into unpowered MCU I/O pins during deep sleep, eliminating risk of latch-up or data corruption. |

IC Role / Device Role / Timing Role: Signal conditioning gate enabling bidirectional voltage translation without external biasing. Use Value: 5.5V-tolerant inputs accept 24V-scaled logic directly via resistor divider, reducing component count vs. dedicated level shifter ICs. |
| Automotive Infotainment Power Sequencing | Medical Diagnostic Equipment Logic Interface |
|
Use Scenario: Controlling enable sequencing of display backlight and audio amplifier rails during cold boot. IC Role / Device Role / Timing Role: Combinatorial logic element generating synchronized power-enable pulses from reset and clock signals. Use Value: Sub-6ns propagation delay ensures tight timing alignment between subsystem power-ups, avoiding brown-out conditions. |
Use Scenario: Interfacing legacy 5V TTL sensors with modern 1.8V ADC controllers in portable ultrasound units. IC Role / Device Role / Timing Role: Voltage-domain translator and noise filter for analog front-end trigger lines. Use Value: Low 14pF CPD minimizes signal distortion on fast edge-triggered acquisition clocks, preserving time-of-flight accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Same logic function and 1.65–5.5V range; SOT-23-5 package (same footprint as SOT25); IOFF supported; AEC-Q100 not specified | Qualified only for commercial/industrial temp range (–40°C to +85°C); lacks automotive qualification documentation and PPAP support | Select when automotive qualification is unnecessary and cost optimization is prioritized over extended temperature validation |
| 74LVC1G02GW,125 | NXP variant in SOT353 package; identical electrical specs; AEC-Q100 Grade 1 qualified; θJA = 385°C/W (higher thermal resistance) | Smaller 2.15mm × 2.1mm footprint but significantly worse thermal performance; unsuitable for high-duty-cycle or high-ambient environments | Select only when PCB space is constrained and thermal load remains below 10mW average under worst-case conditions |
Compared with SN74LVC1G02DBVR and 74LVC1G02GW,125, the 74LVC1G02QW5-7 uniquely balances AEC-Q100 Grade 1 compliance, SOT25 thermal performance (θJA = 184°C/W), and drop-in compatibility with industrial-grade LVC NOR gates-making it optimal for thermally demanding automotive modules where qualification traceability is mandatory.

FAQ
Can 74LVC1G02QW5-7 operate reliably at 1.65V supply while driving a 30pF load?
Yes. The device is fully characterized down to 1.65V: propagation delay is 10.5ns max, output drive is ±4mA, and VOH/VOL remain within specification (VOH ≥ 0.95V, VOL ≤ 0.70V). These values ensure clean switching into 30pF loads at minimum VCC, validated per AEC-Q100 test conditions.
What is the maximum allowable input transition rate (dV/dt) for reliable operation?
The datasheet specifies Δt/ΔV limits: 20 ns/V at 1.8V, 10 ns/V at 3.3V, and 5 ns/V at 5V. Exceeding these rates risks false triggering due to internal node coupling; design must ensure input rise/fall times meet these thresholds across the full temperature range.
Does IOFF functionality require external pull-up or pull-down resistors on the output?
No. IOFF is fully internal: when VCC = 0V, the output automatically transitions to high-impedance state without external components. However, unused inputs must be tied to VCC or GND per datasheet Note 6 to prevent floating node oscillation and excess current draw.
How does thermal performance differ between SOT25 and SOT353 packages?
SOT25 has θJA = 184°C/W; SOT353 has θJA = 385°C/W - nearly double the junction-to-ambient resistance. Under identical 24mA output load and ambient conditions, SOT353 junction temperature rises ~40°C higher, limiting usable duty cycle in enclosed automotive enclosures above 85°C ambient.
