Product details
Overview
74LVC1G00QW5-7 from Diodes Incorporated is an automotive-grade single 2-input positive NAND gate in SOT25 package, operating from 1.65V to 5.5V 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 engine control units and ADAS domain controllers.
For engineers reviewing the 74LVC1G00QW5-7 datasheet, 74LVC1G00QW5-7 pinout, 74LVC1G00QW5-7 application, or 74LVC1G00QW5-7 equivalent, this page delivers verified AEC-Q100 Grade 1 specifications, SOT25 pin mapping, real-world logic isolation use cases, and validated drop-in alternatives for automotive embedded designs.
Technical Context
This device implements a standard positive-logic NAND function (Y = A·B) with push-pull CMOS output stage and integrated IOFF circuitry that disables outputs during power-down to prevent backflow current. Its input tolerance up to 5.5V enables interoperability across mixed-voltage domains without external level shifters.
Designed for automotive Grade 1 operation (–40°C to +125°C), it meets AEC-Q100 stress tests including >2000V HBM ESD, >1000V CDM, and >100mA latch-up immunity-ensuring robustness in under-hood electronics where thermal cycling and electrical transients are common.
Key Specifications

| IOFF partial power-down support | Automatically disables output when VCC = 0V, preventing back-current into powered-down sections-essential for modular vehicle architectures with independent domain power gating. |
| 5.5V-tolerant inputs | Eliminates need for external level translators when interfacing with legacy 5V sensors or microcontrollers while operating from modern low-voltage rails. |
| Low dynamic power consumption | Typical CPD = 16pF at 10MHz; reduces switching current and heat generation in dense logic clusters typical in body control modules. |
| Lead-free & halogen-free "Green" construction | Fully RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb); satisfies automotive OEM environmental requirements and simplifies end-of-life recycling. |
Applications
| Engine Control Unit (ECU) Signal Conditioning | ADAS Camera Module Power Sequencing |
|---|---|
|
Use Scenario: Isolating diagnostic enable signals during ECU sleep mode to prevent leakage into powered-down CAN transceivers. IC Role / Device Role / Timing Role: NAND gate configured as active-low enable shutoff; IOFF blocks reverse current when main 5V rail is off but 12V wake line remains active. Use Value: Extends battery standby time by eliminating parasitic drain paths without adding discrete MOSFETs or complex sequencing ICs. |
Use Scenario: Generating synchronized reset pulses for image sensor and ISP during cold boot of forward-facing camera system. IC Role / Device Role / Timing Role: Combining power-good and clock-ready signals to produce clean, glitch-free reset assertion only when both conditions are met. Use Value: Prevents sensor initialization failures caused by marginal timing margins, improving first-frame reliability in automotive vision systems. |
| Body Control Module (BCM) LED Driver Enable Logic | Electric Power Steering (EPS) Torque Sensor Interface |
|
Use Scenario: Enabling high-side LED drivers only when ignition is ON and door-open signal is asserted-preventing inadvertent illumination during service. IC Role / Device Role / Timing Role: NAND gate acting as dual-input safety interlock; output drives enable pin of LED driver IC with rail-to-rail swing. Use Value: Reduces BOM count by replacing discrete AND+inverter logic with one compact, qualified gate-saving PCB area in space-constrained BCMs. |
Use Scenario: Validating torque sensor data integrity by combining CRC pass/fail and sensor ready flags before forwarding to EPS MCU. IC Role / Device Role / Timing Role: Logic-level arbitration gate ensuring torque commands are only accepted when sensor self-test completes successfully. Use Value: Adds hardware-enforced fault containment layer, meeting ASIL-B functional safety requirements without software overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DBVR | Same logic function and 1.65–5.5V range, but rated only to +85°C industrial temp; no AEC-Q100 qualification; SOT-23-5 package (same footprint as SOT25). | Not suitable for under-hood automotive use; acceptable for cabin infotainment or non-safety industrial controls. | Select when cost sensitivity outweighs temperature or qualification requirements-and when AEC-Q100 is not mandated. |
| 74LVC1G00GW,125 | NXP variant in SOT353 package (2.0×2.0mm); identical AEC-Q100 Grade 1 rating and electrical specs, but smaller footprint and higher thermal resistance (θJA = 385°C/W vs. 184°C/W). | Better for ultra-compact layouts where board space is constrained, but requires careful thermal design in high-power-density modules. | Prefer when PCB real estate is premium and thermal load is low; verify junction temperature rise under worst-case IOL conditions. |
Compared with SN74LVC1G00DBVR and 74LVC1G00GW,125, the 74LVC1G00QW5-7 uniquely balances AEC-Q100 compliance, SOT25 thermal performance (θJA = 184°C/W), and industry-standard 0.95mm pitch for automated assembly-making it optimal for production automotive ECUs requiring long-term reliability and manufacturability.

FAQ
Can 74LVC1G00QW5-7 operate reliably at 1.65V supply with full-speed switching?
Yes. The device is fully characterized down to 1.65V: propagation delay is 10.5ns max at 1.8V, and output drive remains functional at ±4mA. At 1.65V, timing margin increases slightly but remains within specification for ≤10MHz toggling-verified across –40°C to +125°C per DS39785 Rev. 2-2.
What is the maximum capacitive load this NAND gate can drive without signal degradation?
Based on switching characteristics and CPD = 16pF, the gate reliably drives ≤50pF loads at 3.3V with tPD ≤6.0ns. For heavier loads (>100pF), observed rise/fall times exceed 10ns, risking setup/hold violations in synchronous interfaces-add a buffer stage if driving long traces or multiple fanouts.
Does IOFF functionality activate automatically during power loss, or require external control?
IOFF activates autonomously when VCC drops below ~0.8V-no external enable signal needed. The internal circuit detects VCC collapse and disables the output FETs within nanoseconds, limiting back-current to ±2μA. This behavior is intrinsic to the silicon design and requires no PCB modifications.
How does the SOT25 package compare thermally to SOT353 for continuous operation at 125°C ambient?
SOT25's θJA = 184°C/W (vs. SOT353's 385°C/W) yields ~35°C lower junction temperature at 24mA IOL in typical 2oz copper layout. At 125°C ambient, SOT25 maintains TJ < 150°C (absolute max), while SOT353 risks exceeding limits-making SOT25 preferred for thermally demanding under-hood placements.
