Product details
Overview
74LVC1G04QSE-7 from Diodes Incorporated is an automotive-grade single CMOS inverter gate with push-pull output, operating from 1.65V to 5.5V supply, delivering ±24mA drive at 3.3V, featuring 5.5V-tolerant inputs and IOFF partial-power-down protection. It performs the Boolean NOT function (A → Y) and is qualified for Grade 1 automotive applications (-40°C to +125°C).
For engineers reviewing the 74LVC1G04QSE-7 datasheet, 74LVC1G04QSE-7 pinout, 74LVC1G04QSE-7 application, or 74LVC1G04QSE-7 equivalent, key selection criteria include input voltage tolerance, IOFF leakage (<±2μA), propagation delay (5.5ns typ @ 3.3V), thermal resistance (385°C/W for SOT353), and AEC-Q100 qualification status.
Technical Context
This device implements a single inverting logic gate with rail-to-rail CMOS output stage and input clamp diodes enabling 5.5V tolerance independent of VCC. Its IOFF circuit actively disables output during power-down, blocking reverse current flow when VCC = 0V.
The logic function is strictly combinational (no internal latching or timing elements), with propagation delay tightly specified across temperature (-40°C to +125°C) and supply (1.65V–5.5V), and input transition rate support up to 20 ns/V at 1.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Inverting buffer (Y = NOT A); enables signal polarity reversal without delay-dependent feedback paths. |
| Supply Voltage Range | 1.65V to 5.5V; supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains. |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC; allows safe level shifting from higher-voltage peripherals into lower-VCC systems. |
| IOFF Leakage Current | ±2 μA max at 5.5V; prevents back-drive damage during partial power-down in multi-rail systems. |
| Propagation Delay | 5.5 ns typical at 3.3V, 25°C; ensures predictable timing in high-speed control and isolation paths. |
| Output Drive Strength | ±24 mA at 3.3V; sufficient to drive multiple LVC loads or small capacitive nodes without external buffering. |
| ESD Robustness | 2000V HBM, 1000V CDM per AEC-Q100; meets automotive board-level ESD immunity requirements. |
Pinout & Package
SOT353 (5-pin, 2.15mm × 2.1mm × 1.1mm, 0.65mm pitch) surface-mount package with exposed pad not present; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | CMOS-compatible logic input with 5.5V tolerance; must be tied to VCC or GND if unused per design guidelines. |
| 2 (GND) | Ground Reference | Primary return path for output current and internal bias; requires low-impedance PCB connection. |
| 3 (Y) | Output | Inverted logic output with push-pull structure; sinks or sources up to ±24mA at 3.3V. |
| 4 (VCC) | Power Supply | Single-supply rail for core logic and I/O; supports wide-range operation from 1.65V to 5.5V. |
| 5 (NC) | No Connection | Internally unconnected pin; must remain floating-no PCB trace or solder mask opening required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 Qualification | Validated for -40°C to +125°C ambient operation in automotive ECUs, body controllers, and ADAS sensor interfaces. |
| IOFF Partial Power-Down Protection | Automatically disables output when VCC = 0V, preventing back-current into powered subsystems during hot-swap or sleep transitions. |
| 5.5V-Tolerant Inputs | Enables direct connection to legacy 5V microcontrollers or sensors without external level-shifting components. |
| Low Dynamic Power Consumption | Typical CPD = 16 pF at 3.3V/10MHz; reduces switching noise and system-level power budget in battery-sensitive modules. |
| Lead-Free & Halogen-Free Construction | Fully RoHS 3 compliant with <900ppm Br+Cl and <1000ppm Sb; satisfies Tier-1 automotive material declaration requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single inverter gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Same logic function and 1.65–5.5V supply, but rated only to +85°C ambient; no AEC-Q100 qualification. | Not suitable for under-hood automotive use; limited to commercial/industrial environments. | Select when cost sensitivity outweighs automotive qualification and extended temperature needs. |
| 74AUP1G04GW,125 | Lower static current (0.9μA max ICC), wider VCC range (0.8–3.6V), but no 5.5V input tolerance or IOFF. | Lacks mixed-voltage interoperability and power-down isolation capability. | Prefer for ultra-low-power battery-operated devices where input voltage matching is guaranteed. |
Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the 74LVC1G04QSE-7 uniquely combines AEC-Q100 Grade 1 qualification, 5.5V input tolerance, and IOFF-making it the only choice for automotive power sequencing and mixed-rail isolation where reliability and safety certification are mandatory.

FAQ
Is the 74LVC1G04QSE-7 pin-compatible with standard 74LVC1G04 packages?
Yes-the 74LVC1G04QSE-7 uses the SOT353 package (5-pin, 0.65mm pitch), identical in footprint and pinout to non-automotive 74LVC1G04 variants in the same package code. Pin 1 is A (input), Pin 3 is Y (output), Pin 4 is VCC, Pin 2 is GND, and Pin 5 is NC. No layout changes are needed for drop-in replacement in AEC-Q100-compliant designs.
What is the maximum capacitive load this inverter can drive reliably?
The 74LVC1G04QSE-7 is characterized up to 50pF load capacitance in switching tests (per DS39787 Rev. 2-2, Figure 1). With ±24mA drive at 3.3V and 5.5ns typical tPD, it reliably drives loads ≤50pF while maintaining timing specs across -40°C to +125°C. For >50pF, propagation delay increases linearly and output rise/fall times degrade-external buffering is recommended beyond this limit.
Does the NC pin require any PCB routing or termination?
No-the NC (No Connection) pin (Pin 5) is internally unconnected and must remain electrically floating. Do not route traces to it, apply solder mask openings, or connect it to VCC/GND. Leaving it unpopulated avoids parasitic coupling and complies with Diodes' recommended layout in package outline AP02007.
How does IOFF behavior affect system-level power sequencing?
When VCC drops below ~0.8V, the IOFF circuit activates and places the Y output in high-impedance state, limiting leakage to ±2μA. This prevents back-driving powered downstream circuits (e.g., 5V I²C buses or MCU GPIOs) during controlled power-down sequences-ensuring deterministic state retention and eliminating latch-up risk in multi-rail automotive ECUs.
