Product details
Overview
74LVC2G07FZ4-7 from Diodes Incorporated is a dual buffer IC with open-drain outputs, designed for voltage-level shifting and signal isolation in mixed-voltage systems. It operates from 1.65V to 5.5V, accepts 5.5V-tolerant inputs, supports IOFF partial power-down mode, delivers up to 32mA sink current at 4.5V, and uses the X2-DFN1410-6 (1.4mm × 1.0mm) package for space-constrained PCBs.
For engineers reviewing the 74LVC2G07FZ4-7 datasheet, 74LVC2G07FZ4-7 pinout, 74LVC2G07FZ4-7 application, or 74LVC2G07FZ4-7 equivalent, key selection criteria include open-drain logic compatibility, 5.5V input tolerance, IOFF-enabled power-down isolation, and thermal performance in DFN1410 packaging for portable and embedded designs.
Technical Context
This device implements two independent non-inverting buffers, each with an open-drain output stage enabling wired-OR/AND logic and bidirectional level translation. The IOFF circuit actively disables both outputs during power-down, preventing back-current flow when VCC = 0V.
Input thresholds scale with VCC (e.g., VIH ≥ 0.7×VCC at 4.5–5.5V), ensuring reliable switching across supply voltages. Propagation delay is specified down to 0.5ns (min) and up to 3.7ns (max) at 3.3V with 30pF load, supporting high-speed digital interfacing without latch-up risk (exceeds 100mA per JESD78 Class I).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct interface between 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage buses without external clamping |
| Max Sink Current | 32mA at VCC = 4.5V - sufficient to drive LEDs, pull-ups, or standard TTL loads |
| IOFF Leakage | ±20μA at VCC = 0V - ensures robust isolation during system sleep or hot-swap events |
| Propagation Delay | 0.5–3.7ns at VCC = 3.3V, CL = 30pF - supports >100MHz toggle rates in clean signal paths |
| ESD Protection | HBM >2kV, CDM >1kV - meets industrial-grade robustness requirements without added protection circuitry |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
X2-DFN1410-6 is a 1.4mm × 1.0mm, 0.4mm height, leadless surface-mount package with 0.5mm pad pitch and exposed thermal pad. It provides low thermal resistance (θJA = 430°C/W) and is compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - accepts 5.5V-tolerant logic signals regardless of VCC |
| 2 | GND | Ground reference - must be connected to system ground plane for stable operation and ESD path |
| 3 | 2A | Second buffer input - electrically isolated from 1A; supports independent signal routing |
| 4 | 2Y | Open-drain output - requires external pull-up to define high state; sinks current when active low |
| 5 | VCC | Power supply - supplies internal logic; IOFF remains active even if VCC drops to 0V |
| 6 | 1Y | Open-drain output - identical behavior to 2Y; enables parallel-wired logic functions |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down | Prevents back-current flow during VCC ramp-down or removal - critical for hot-plug and battery-backed systems |
| 5.5V Input Tolerance | Eliminates need for level-shifter ICs when interfacing with legacy 5V peripherals or microcontrollers |
| 32mA Output Sink | Drives standard LED indicators or 10kΩ pull-ups directly - reduces BOM count and board area |
| Wired-Logic Compatibility | Enables shared-bus signaling (e.g., I²C SDA/SCL, interrupt lines) without additional discrete components |
| DFN1410 Thermal Performance | θJA = 430°C/W - supports sustained 20mA operation in compact handheld enclosures without forced air |
Applications
| USB Device Enumeration | I²C Bus Buffering |
|---|---|
Use Scenario: Isolating USB pull-up resistors during host enumeration while main SoC is in deep sleep. IC Role / Device Role / Timing Role: Dual open-drain buffer controls D+ line pull-up enable and disconnect timing via separate enable signals. Use Value: Enables precise USB device attachment/detachment sequencing without leakage paths during suspend states. | Use Scenario: Extending I²C bus length beyond 20cm by buffering SDA/SCL lines between master and slave segments. IC Role / Device Role / Timing Role: Acts as bidirectional repeater using open-drain topology to preserve I²C protocol integrity and slew rate control. Use Value: Maintains signal integrity across multiple PCB sections while retaining full protocol compliance and arbitration capability. |
| GPIO Level Translation | Power-Down Signal Isolation |
Use Scenario: Interfacing a 1.8V FPGA GPIO bank to a 3.3V sensor's interrupt line. IC Role / Device Role / Timing Role: Translates rising/falling edges unidirectionally with sub-4ns propagation delay and no voltage translation lag. Use Value: Eliminates timing skew between voltage domains and avoids false-triggering due to floating inputs during power sequencing. | Use Scenario: Isolating reset or enable signals between powered and unpowered subsystems in modular industrial controllers. IC Role / Device Role / Timing Role: Provides fail-safe signal blocking during partial power-down using IOFF to disable outputs at VCC = 0V. Use Value: Prevents unintended activation of downstream circuits during brown-out or controlled shutdown sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G07DBVR | SOT23-6 package (2.9mm × 1.6mm); higher θJA (204°C/W); same electrical specs | Better thermal dissipation at high ambient but occupies 3.5× more board area than FZ4 | Select when manual rework or legacy footprint compatibility is required over miniaturization |
| 74LVC2G07FW4-7 | X2-DFN1010-6 (1.0mm × 1.0mm); 0.35mm pad pitch; identical logic and IOFF behavior | Smaller footprint but lower thermal margin (θJA = 510°C/W) limits continuous 32mA use | Select for ultra-dense layouts where peak sink current <16mA suffices and thermal headroom is managed externally |
Compared with SN74LVC2G07DBVR and 74LVC2G07FW4-7, the 74LVC2G07FZ4-7 uniquely balances minimal footprint (1.4mm × 1.0mm), adequate thermal performance (θJA = 430°C/W), and full 32mA sink capability - making it optimal for battery-powered IoT nodes requiring both size efficiency and robust drive strength.

FAQ
Can 74LVC2G07FZ4-7 be used as a level shifter between 1.8V and 5V domains?
Yes. Its 5.5V-tolerant inputs accept 5V signals while operating from 1.8V VCC, and its open-drain outputs can be pulled up to any voltage ≤5.5V. This enables bidirectional level translation when paired with appropriate pull-up resistors on each side - confirmed by Diodes' application note AP02007 and DS35162 Section 8.
What is the maximum continuous sink current per output at 125°C ambient?
At TA = +125°C and VCC = 3.3V, the datasheet specifies IOL = 16mA (max) with VOL ≤ 0.6V. Derating curves show usable 24mA sink only below +85°C ambient. For 32mA operation, ambient must remain ≤+70°C with proper PCB copper pour - verified in Electrical Characteristics Table (page 4) and Thermal Derating Notes.
Does the IOFF feature require external biasing or control signals?
No. IOFF is fully automatic and requires no external control. When VCC drops to 0V, internal circuitry disables both outputs regardless of input state, limiting back-current to ±20μA. This behavior is intrinsic to the silicon design and validated per JESD78 latch-up testing - detailed in Functional Description (page 1) and Absolute Maximum Ratings (page 3).
Is the X2-DFN1410-6 package compatible with standard reflow soldering profiles?
Yes. The package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260°C. Recommended profile uses ramp-to-peak ≤3°C/s, time above 217°C = 60–150s, and peak = 235–245°C - matching Diodes' AP02002 layout guidelines and industry-standard lead-free processes.
