Product details
Overview
SN74LVC3G07DCUTE4 from Texas Instruments is a triple non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 5.5-V VCC operation. It delivers 3.7 ns max propagation delay at 3.3 V, ±24-mA output drive capability, and supports Ioff partial-power-down protection. It is used in level-shifting, wired-OR logic, and bus interface applications where active-low pull-down control is required.
For engineers reviewing the SN74LVC3G07DCUTE4 datasheet, SN74LVC3G07DCUTE4 pinout, SN74LVC3G07DCUTE4 application, or SN74LVC3G07DCUTE4 equivalent, key selection considerations include open-drain sink current (32 mA max), Ioff-enabled live insertion support, 1.65–5.5 V supply flexibility, and compatibility with mixed-voltage systems up to 5.5 V on inputs/outputs.
Technical Context
This device implements three independent non-inverting buffer stages, each with an open-drain output stage capable of sinking up to 32 mA at 4.5 V. Its Ioff circuitry actively disables outputs during power-down, preventing back-drive current and enabling hot-plug capability.
The input structure accepts voltages up to 5.5 V regardless of VCC level, allowing seamless interfacing between 1.8-V, 2.5-V, 3.3-V, and 5-V domains. Propagation delay remains under 4.2 ns across –40°C to 125°C when operated at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across legacy and low-voltage logic families |
| Max tpd @ 3.3 V | 3.7 ns - ensures timing-critical signal buffering with minimal latency in high-speed digital interfaces |
| IOL Max | 32 mA at 4.5 V - supports direct driving of LEDs, pull-up resistors, or multiple CMOS inputs in wired-OR configurations |
| Ioff Current | ±10 μA max - guarantees isolation during partial power-down, protecting powered subsystems from back-current |
| Input Voltage Tolerance | Up to 5.5 V - allows safe interfacing with higher-voltage controllers without external level shifters |

Pinout & Package
VSSOP (DCU) 8-pin package: ultra-thin (0.9 mm max height), 2.0 mm × 1.6 mm footprint, lead-free NiPdAu/Sn finish, moisture sensitivity level 1, compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input - accepts 0–5.5 V logic signals independent of VCC |
| 2 | GND | Ground reference - common return path for all three buffers and internal circuitry |
| 3 | 1Y (Output) | Open-drain output for Buffer 1 - requires external pull-up; sinks up to 32 mA |
| 4 | 2A (Input) | Second buffer input - electrically isolated from other inputs; same voltage tolerance as 1A |
| 5 | 2Y (Output) | Open-drain output for Buffer 2 - independently controllable; shares no internal nodes with 1Y or 3Y |
| 6 | 3A (Input) | Third buffer input - fully identical in specification and behavior to 1A and 2A |
| 7 | 3Y (Output) | Open-drain output for Buffer 3 - supports individual enable/disable via input control |
| 8 | VCC | Supply voltage - powers internal logic; sets output high-impedance state and defines VOL threshold |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain outputs | Enable wired-OR logic, I²C-compatible bus driving, and flexible pull-up voltage selection (e.g., 3.3 V pull-up with 1.8 V VCC) |

| Low ICC (10 μA max) | Enables use in always-on supervisory circuits without compromising battery life in portable equipment |
Applications
| Industrial Sensor Interface | I²C Bus Extender |
|---|---|
Use Scenario: Connecting multiple 5-V analog sensor outputs to a 3.3-V microcontroller ADC input via open-drain interrupt lines.

Use Value: Enables direct connection without external level shifters; Ioff prevents reverse current when MCU is powered down but sensors remain active. | Use Scenario: Extending I²C SDA line across two PCBs with different ground potentials using a single open-drain driver stage. IC Role / Device Role / Timing Role: SN74LVC3G07DCUTE4 provides galvanically isolated, bidirectional open-drain buffering for SDA, maintaining I²C electrical compliance. Use Value: Supports multi-segment I²C topologies with <3.7 ns propagation delay, preserving timing margins even at 400 kHz operation. |
| LED Driver Interface | Hot-Swappable Module Control |
Use Scenario: Driving common-anode status LEDs from a low-voltage FPGA I/O bank with 1.8-V VCC. IC Role / Device Role / Timing Role: SN74LVC3G07DCUTE4 serves as a current-sinking driver, using its 32-mA sink capability to directly illuminate LEDs with 5-V anodes. Use Value: Eliminates discrete MOSFETs or transistors; 5.5-V input tolerance allows direct FPGA pin connection without series resistors. | Use Scenario: Enabling/disabling power to a peripheral module via a microcontroller GPIO while the main system remains operational. IC Role / Device Role / Timing Role: SN74LVC3G07DCUTE4 controls the gate of an external high-side PMOS switch using its open-drain output and external pull-up. Use Value: Ioff protection ensures no backfeed occurs during module insertion/removal, meeting live-insertion safety requirements. |
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 | Single-channel version in SOT-23-5; identical electrical specs per channel but lower channel count | Suitable only when one buffer is needed; smaller footprint but requires three units for triple functionality | Select SN74LVC1G07DBVR only for space-constrained single-buffer designs where board area outweighs assembly cost |
| 74LVC3G07GM,132 | Nexperia part in XSON-8 package; same logic function and 1.65–5.5 V range, but Ioff not specified and max IOL = 24 mA at 3.3 V | Lacks Ioff support - unsuitable for partial-power-down or hot-swap scenarios requiring back-drive protection | Choose 74LVC3G07GM,132 only in cost-sensitive, full-power-always applications where Ioff is not required |
Compared with SN74LVC3G07DCUTE4, SN74LVC1G07DBVR offers footprint savings at the cost of increased assembly complexity for triple-buffer needs, while 74LVC3G07GM,132 trades Ioff protection and higher sink current for lower unit cost in static-power applications.

FAQ
What is the maximum sink current supported by SN74LVC3G07DCUTE4?
The SN74LVC3G07DCUTE4 supports up to 32 mA sink current per output at VCC = 4.5 V, as specified in the Recommended Operating Conditions table. At 3.3 V, it delivers 24 mA minimum, and at 1.65 V, 4 mA minimum. This makes SN74LVC3G07DCUTE4 suitable for driving LEDs, terminating buses, or pulling down multiple CMOS inputs in wired-OR configurations without external amplification.
Does SN74LVC3G07DCUTE4 support partial power-down operation?
Yes, SN74LVC3G07DCUTE4 includes Ioff circuitry that disables all outputs when VCC = 0 V, limiting off-state current to ±10 μA maximum. This feature prevents damaging back-current flow in mixed-power-domain systems and enables safe live insertion of modules. The Ioff specification is verified across –40°C to 125°C and is integral to SN74LVC3G07DCUTE4's design for industrial and automotive applications.
Can SN74LVC3G07DCUTE4 interface between 5-V and 1.8-V logic domains?
Yes, SN74LVC3G07DCUTE4 accepts input voltages up to 5.5 V regardless of VCC level, and its outputs are open-drain - meaning they do not source current and rely on external pull-ups. When VCC = 1.8 V, SN74LVC3G07DCUTE4 can safely receive 5-V signals and drive a 5-V pull-up, making SN74LVC3G07DCUTE4 ideal for bidirectional level translation in mixed-voltage systems without additional components.
What package type is used for SN74LVC3G07DCUTE4?
SN74LVC3G07DCUTE4 uses the VSSOP (DCU) 8-pin package: 2.0 mm × 1.6 mm body size, 0.9 mm maximum height, 0.5-mm lead pitch, and NiPdAu/Sn lead finish. It is RoHS-compliant, moisture sensitivity level 1, and qualified for reflow per J-STD-020. This compact DCU package supports high-density PCB layouts and automated assembly in consumer and industrial electronics.
Is SN74LVC3G07DCUTE4 pin-compatible with other members of the SN74LVC3Gxx family?
SN74LVC3G07DCUTE4 shares the same DCU-8 pinout with SN74LVC3G14 (Schmitt-trigger inverter) and SN74LVC3G17 (buffer with Schmitt-trigger inputs), but differs from SN74LVC3G04 (inverter) and SN74LVC3G34 (push-pull buffer). Pin compatibility is confirmed by TI's mechanical drawings and package outlines - all DCU-8 variants use identical pad layout and terminal numbering, enabling shared footprint reuse where logic function permits.
