Product details
Overview
74LVC1G07QSE-7 from Diodes Incorporated is an automotive-grade single buffer IC with open-drain output, designed for level-shifting and signal isolation in mixed-voltage systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs regardless of VCC, supports IOFF partial power-down, and delivers 32mA sink current at 5V - used in automotive body control modules for wake-up signal conditioning.
For engineers reviewing the 74LVC1G07QSE-7 datasheet, 74LVC1G07QSE-7 pinout, 74LVC1G07QSE-7 application, or 74LVC1G07QSE-7 equivalent, key selection criteria include open-drain drive capability, AEC-Q100 Grade 1 qualification, IOFF leakage performance, and SOT353 thermal resistance (θJA = 385°C/W).
Technical Context
This device implements a non-inverting buffer with true open-drain output, enabling wired-OR logic and bidirectional voltage translation. Its IOFF circuit actively disables output leakage during power-down, meeting AEC-Q100 requirements for automotive subsystems with staggered supply sequencing.
Input tolerance up to 5.5V allows interfacing with legacy 5V logic while powered from 1.8V or 3.3V rails. Propagation delay ranges from 0.5ns (typ) at 5V to 2.6ns (typ) at 1.8V, supporting timing-critical enable/control paths in infotainment and ADAS domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct integration into 1.8V, 2.5V, 3.3V, and 5V domains without level shifters |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - permits safe connection to higher-voltage buses in mixed-rail systems |
| Max Sink Current | 32mA at VCC = 5V - sufficient to drive LEDs, pull-down resistors, or I²C bus lines directly |
| IOFF Leakage | ±2μA max at VCC = 0V - prevents back-current damage during partial power-down in ECU submodules |
| Propagation Delay | 0.5ns (typ) to 4.5ns (max) at 5V - meets setup/hold timing for microcontroller GPIO wakeup signals |
| Operating Temperature | −40°C to +125°C (Grade 1) - qualified for under-hood automotive applications per AEC-Q100 |
| ESD Protection | 2kV HBM, 1kV CDM - exceeds AEC-Q100-002/-011 for robustness in manufacturing and field environments |
Pinout & Package
SOT353 (5-pin, 2.15mm × 2.1mm × 1.1mm, 0.65mm pitch) - compact 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 | Non-inverting data input; 5.5V-tolerant, accepts logic high/low referenced to any VCC in range |
| 2 (GND) | Ground | Reference return path for all internal logic and output sink current |
| 3 (Y) | Open-Drain Output | Active-low output requiring external pull-up; supports wired-AND/OR and bidirectional bus operation |
| 4 (VCC) | Supply | Core logic and IOFF control rail; powers internal circuitry and defines input threshold levels |
| 5 (NC) | No Connection | Internally unconnected pin; must remain floating or grounded per layout guidelines - no routing or soldering |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down | Enables safe hot-plug and subsystem sleep modes by disabling output leakage when VCC = 0V |
| 5.5V Input Tolerance | Eliminates need for external clamping diodes when interfacing with 5V sensors or legacy microcontrollers |
| Grade 1 Automotive Qualification | Fully AEC-Q100 qualified, PPAP-capable, and manufactured in IATF 16949-certified facilities |
| Low Dynamic Power | Typical ICC = 0.1μA at 5.5V - reduces quiescent current in always-on vehicle networks (e.g., LIN/CAN wake lines) |
| Open-Drain Flexibility | Supports active-low interrupt signaling, I²C-compatible bus arbitration, and multi-source wired-OR wake-up lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Same logic function and 1.65–5.5V range, but rated only to +85°C; no AEC-Q100 qualification; SOT-23-5 package (larger footprint, θJA = 184°C/W) | Not suitable for under-hood or chassis-mounted automotive use; acceptable for commercial-grade industrial controls | Select when cost or thermal performance (lower θJA) outweighs automotive qualification requirements |
| NX1LZ07GM | Pin-compatible, AEC-Q100 Grade 1, but specifies only 20mA sink at 5V; IOFF leakage ≤ ±5μA (vs. ±2μA); slightly higher tPD (6.5ns max at 5V) | Marginally lower drive strength and higher leakage may impact long-trace or ultra-low-power designs | Prefer when sourcing from Nexperia's extended automotive portfolio is required for supply chain diversification |
Compared with SN74LVC1G07DBVR and NX1LZ07GM, the 74LVC1G07QSE-7 offers tighter IOFF leakage, higher sink current, and verified thermal performance in SOT353 - making it optimal for space-constrained, thermally demanding automotive nodes where reliability and timing margin are critical.

FAQ
Can the 74LVC1G07QSE-7 be used as a level shifter between 1.8V and 5V logic domains?
Yes. Its 5.5V-tolerant inputs allow direct connection to 5V sources while powered from 1.8V, and its open-drain output can be pulled up to any voltage ≤5.5V. This enables bidirectional level shifting without direction control pins, commonly used on I²C or interrupt lines in automotive gateway modules.
What is the maximum recommended pull-up resistor value for the Y output at 5V supply?
For 32mA sink capability and <0.55V VOL, the maximum pull-up resistor is 139Ω (calculated as (5V − 0.55V)/32mA). In practice, 1kΩ to 10kΩ is typical for signal integrity and power savings; values >100kΩ risk exceeding VOL spec under full load or high temperature.
Does the NC pin (Pin 5) require any PCB layout treatment?
Pin 5 is internally unconnected and must remain electrically floating. Do not connect it to GND, VCC, or any trace. Maintain clearance per SOT353 pad layout guidelines; solder mask should fully cover the pad to prevent accidental shorting during reflow or handling.
How does IOFF behavior affect system-level power sequencing in automotive applications?
When VCC drops below ~0.2V, IOFF activates and limits output leakage to ±2μA, preventing current flow from powered downstream circuits (e.g., 5V CAN transceivers) into the unpowered buffer. This avoids unintended wake events and protects upstream power supplies during controlled subsystem shutdown sequences.
