Product details
Overview
74LVC1G00QSE-7 from Diodes Incorporated is an automotive-grade single 2-input positive NAND gate in SOT353 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. It performs Boolean Y = A·B and is qualified per AEC-Q100 Grade 1 (–40°C to +125°C) for use in automotive signal isolation and level-shifting circuits.
For engineers reviewing the 74LVC1G00QSE-7 datasheet, 74LVC1G00QSE-7 pinout, 74LVC1G00QSE-7 application, or 74LVC1G00QSE-7 equivalent, key selection criteria include supply voltage flexibility, 5.5V input tolerance in mixed-voltage systems, IOFF leakage <±2μA during power-down, and propagation delay ≤6.0ns at 3.3V.
Technical Context
This device implements a single inverting logic gate with complementary CMOS structure, supporting rail-to-rail input operation up to 5.5V independent of VCC. Its IOFF circuit actively disables output drivers when VCC = 0V, preventing back-current flow in partial-power-down configurations common in automotive domain controllers.
The gate exhibits consistent switching performance across 1.65–5.5V supply range: tPD = 6.0ns (max) at 3.3V/25°C, with VIH/VIL thresholds scaling with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V). Input capacitance is 5.0pF, and CPD = 16pF at 10MHz, enabling low-noise, low-power logic interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Positive NAND: Y = A·B - provides active-low output for enable/inhibit control in power sequencing and reset circuits. |
| Supply Voltage Range | 1.65V to 5.5V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection of higher-voltage signals (e.g., 5V microcontroller GPIO) to lower-VCC logic domains. |
| IOFF Leakage Current | ±2 μA max - ensures negligible current backflow during system sleep states, critical for battery-powered automotive modules. |
| Output Drive Strength | ±24 mA at 3.3V - sufficient to drive multiple 74LVC inputs or small LEDs directly without external buffers. |
| Propagation Delay | 6.0 ns max at 3.3V - enables reliable timing in high-speed control loops such as CAN transceiver enable/disable or sensor data gating. |
| Operating Temperature | –40°C to +125°C (Grade 1) - validated for under-hood automotive environments including engine control units and body electronics. |
Pinout & Package
SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65mm pitch) - ultra-compact 5-pin surface-mount package with exposed pad not present; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Primary logic input; accepts 0–5.5V regardless of VCC - enables mixed-voltage signal routing. |
| 2 (B) | Data Input | Secondary logic input; electrically identical to Pin 1; both inputs must be driven to avoid floating-state uncertainty. |
| 3 (GND) | Ground Reference | Return path for all internal currents; must be connected before VCC to prevent latch-up during power sequencing. |
| 4 (Y) | Data Output | Push-pull CMOS output; sinks or sources up to ±24mA; IOFF disables this pin when VCC = 0V. |
| 5 (VCC) | Power Supply | Core supply input; powers internal logic and output stage; IOFF activation requires VCC = 0V detection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C operation with full PPAP support - meets OEM requirements for engine bay and chassis electronics. |
| IOFF partial power-down | Active output disable at VCC = 0V limits back-current to ±2μA - eliminates need for external isolation switches in multi-rail systems. |
| 5.5V-tolerant inputs | Accepts 5V signals while powered from 1.8V or 3.3V - simplifies interconnection between legacy and modern MCU peripherals. |
| Low dynamic power | CPD = 16pF at 10MHz - reduces switching noise and supply ripple in EMI-sensitive automotive infotainment and ADAS subsystems. |
| ESD robustness | 2kV HBM / 1kV CDM - exceeds AEC-Q100-002/-011 requirements for handling and board assembly reliability. |
Applications
| Engine Control Unit (ECU) Power Sequencing | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Enabling/disabling auxiliary power rails based on ignition state and CAN bus activity. IC Role / Device Role / Timing Role: NAND gate acts as an AND-NOT combiner for wake-up signals and microcontroller readiness flags.

|
Use Scenario: Controlling MIPI CSI-2 clock enable to image sensor during camera initialization and error recovery. IC Role / Device Role / Timing Role: NAND gate generates synchronized enable pulse by combining SoC reset and PLL lock status. Use Value: 6.0ns max propagation delay ensures sub-10ns timing margin for 100MHz+ pixel clocks, preserving video frame integrity. |
Use Scenario: Coordinating cold reset assertion across audio DSP, display controller, and Bluetooth SoC upon ignition-on event. IC Role / Device Role / Timing Role: Single gate combines ignition voltage detect and watchdog timeout signals to generate system-wide reset. Use Value: ±24mA drive strength directly drives reset inputs of three downstream ICs without buffer amplification, reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DBVR | Same logic function and 1.65–5.5V supply, but rated only to +85°C industrial temp; no AEC-Q100 qualification; SOT-23-5 package (3.0×2.8mm). | Not suitable for under-hood automotive use; acceptable for cabin-infotainment or industrial control panels. | Select when Grade 1 temperature rating and PPAP documentation are not required. |
| 74LVC1G00GW,125 | NXP variant in SC-70 (SOT323) package; identical electrical specs and AEC-Q100 Grade 1 qualification; slightly higher tPD (7.0ns max at 3.3V). | Compatible in automotive applications but requires PCB redesign due to different footprint and thermal resistance (θJA = 390°C/W vs. 385°C/W). | Choose when existing NXP supply chain or SC-70 placement infrastructure is preferred over Diodes' SOT353 layout. |
Compared with SN74LVC1G00DBVR and 74LVC1G00GW,125, the 74LVC1G00QSE-7 offers the smallest footprint (2.0×2.0mm), lowest thermal resistance in its class (θJA = 385°C/W), and full automotive change-control documentation - making it optimal for space-constrained, thermally demanding ECU designs requiring zero-defect traceability.

FAQ
Can 74LVC1G00QSE-7 operate with 1.65V supply while accepting 5V inputs?
Yes. The device is explicitly specified for 1.65V to 5.5V VCC operation and features 5.5V-tolerant inputs - meaning Pin A and Pin B accept 0–5.5V signals regardless of VCC level. This enables direct interfacing between 5V sensors and 1.8V microcontrollers without external level shifters.
What happens to the output during power-down when VCC = 0V?
When VCC drops to 0V, the IOFF circuit automatically disables the output driver, placing Pin Y in high-impedance state with leakage ≤±2μA. This prevents reverse current flow from other powered rails into the unpowered device - a critical requirement for automotive partial-sleep modes.
Is the SOT353 package compatible with standard reflow profiles?
Yes. The SOT353 package has Moisture Sensitivity Level 1 per J-STD-020, requiring no dry-pack or baking prior to assembly. It supports standard lead-free reflow profiles with peak temperature up to 260°C and is qualified for soldering per MIL-STD-202, Method 208.
How does the 74LVC1G00QSE-7 differ from non-automotive 74LVC1G00 variants?
It differs in three verified ways: (1) AEC-Q100 Grade 1 qualification (-40°C to +125°C), (2) PPAP-capable manufacturing in IATF 16949-certified facilities, and (3) enhanced ESD (2kV HBM) and latch-up (>100mA) test compliance per automotive standards - not found in commercial-grade equivalents.
