Product details
Overview
SN74LVC3G07DCUTG4 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 sink drive, 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 SN74LVC3G07DCUTG4 datasheet, SN74LVC3G07DCUTG4 pinout, SN74LVC3G07DCUTG4 application, or SN74LVC3G07DCUTG4 equivalent, this page provides verified pin mapping, real-world timing and drive specifications, thermal and ESD performance data, and validated alternative options for industrial and embedded system design.
Technical Context
The SN74LVC3G07DCUTG4 implements three independent non-inverting buffers, each with an open-drain output stage capable of sinking up to 32 mA at 4.5 V. Its Ioff circuitry disables outputs during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and live-insertion systems.
All inputs accept voltages up to 5.5 V regardless of VCC level, enabling mixed-voltage interfacing (e.g., 1.8-V logic driving 5-V buses). The device operates across –40°C to +125°C and meets JESD 78 Class II latch-up immunity (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 200-V MM, 1000-V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. |
| Max tpd | 3.7 ns at VCC = 3.3 V - enables high-speed signal buffering in timing-critical interfaces like I²C and SMBus. |
| IOL (max) | 32 mA at VCC = 4.5 V - sufficient to directly drive LEDs, MOSFET gates, or multiple CMOS inputs in wired-OR configurations. |
| Ioff Current | ±10 μA max - ensures safe isolation during partial power-down, eliminating risk of current backflow into powered subsystems. |
| Input Voltage Tolerance | Up to 5.5 V - allows interfacing with higher-voltage peripherals without external level shifters. |
| ESD Rating | 2000-V HBM - meets industrial-grade robustness requirements for board-level handling and field deployment. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-temperature embedded applications. |
Pinout & Package
VSSOP (DCU) package, 8-pin, 2.0 mm × 1.25 mm footprint, 0.5-mm pitch, 0.9-mm max height. RoHS-compliant, NIPDAU lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | Input for Buffer 1 - accepts 0–5.5 V logic; compatible with all standard LVC input thresholds. |
| 2 | GND | Ground reference - must be connected to system ground plane for stable noise margin and thermal dissipation. |
| 3 | 2A | Input for Buffer 2 - electrically isolated from other inputs; supports independent signal routing. |
| 4 | 2Y | Open-drain output for Buffer 2 - requires external pull-up to define high state; sinks up to 32 mA. |
| 5 | VCC | Power supply - supplies internal logic and output driver; decoupling capacitor (0.1 μF) recommended near pin. |
| 6 | 3Y | Open-drain output for Buffer 3 - shares no internal connection with 1Y or 2Y; enables independent bus control. |
| 7 | 3A | Input for Buffer 3 - fully identical in electrical behavior to Pins 1 and 3; supports synchronous or asynchronous use. |
| 8 | 1Y | Open-drain output for Buffer 1 - functionally identical to Pins 4 and 6; enables parallel or cascaded wired-OR implementation. |
Key Features
| Feature | Design Value |
|---|---|
| Triple open-drain buffer | Three independent channels allow simultaneous control of separate buses or loads without crosstalk. |
| Ioff partial-power-down | Enables safe insertion/removal in live systems by disabling outputs and blocking reverse current at VCC = 0 V. |
| NanoFree™ packaging | Dies-as-packages reduce thermal resistance (θJA = 227°C/W) and improve board space efficiency vs. traditional SOIC. |
| 5.5-V tolerant inputs | Eliminates need for external level translators when interfacing with legacy 5-V peripherals or sensors. |
| Low ICC (10 μA max) | Reduces standby power in battery-powered IoT nodes and portable instrumentation without sacrificing drive capability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G07DCURG4 | Same silicon, VSSOP (DCU) package, 3000-unit reel - differs only in packaging quantity and tape/reel configuration. | No functional difference; suitable for high-volume automated assembly where large reels reduce changeover frequency. | Select SN74LVC3G07DCURG4 for production runs ≥5k units; SN74LVC3G07DCUTG4 preferred for prototyping and low-volume builds. |
| SN74LVC1G07DBVR | Single-channel version in SOT-23-5 package; identical electrical specs but only one buffer per unit. | Requires three units to match channel count; increases board area and assembly cost vs. integrated triple solution. | Choose SN74LVC1G07DBVR only when design requires physical separation of buffer channels or incremental scalability. |
Compared with SN74LVC3G07DCURG4, SN74LVC3G07DCUTG4 offers identical performance in a smaller reel format ideal for engineering validation; versus SN74LVC1G07DBVR, it delivers 66% lower component count and 40% smaller total footprint for triple-buffer implementations.

FAQ
What is the maximum sink current supported by each output of the SN74LVC3G07DCUTG4?
Each open-drain output of the SN74LVC3G07DCUTG4 supports up to 32 mA sink current at VCC = 4.5 V, as specified in the Electrical Characteristics table under IOL. At 3.3 V, the rated sink current is 24 mA. This enables direct driving of LEDs, small relays, or MOSFET gates without external amplification - a key design advantage confirmed in the SCES365K datasheet.
Does the SN74LVC3G07DCUTG4 support partial power-down operation?
Yes, the SN74LVC3G07DCUTG4 includes Ioff circuitry that actively disables all outputs when VCC = 0 V, limiting Ioff current to ±10 μA maximum. This feature prevents damaging current backflow during live insertion or system power sequencing - explicitly documented in the FEATURES and Absolute Maximum Ratings sections of the TI datasheet.
What package type and dimensions does the SN74LVC3G07DCUTG4 use?
The SN74LVC3G07DCUTG4 uses the VSSOP (DCU) package: 8-pin, 2.0 mm × 1.25 mm body size, 0.5-mm lead pitch, and 0.9-mm maximum height. Mechanical drawings confirm pin 1 orientation in Quadrant Q3 of the tape reel. This compact footprint is validated in TI's PACKAGE OUTLINE DCU0008A document dated September 2014.
Can the SN74LVC3G07DCUTG4 interface between 1.8-V and 5-V logic domains?
Yes - all inputs of the SN74LVC3G07DCUTG4 tolerate voltages up to 5.5 V independent of VCC level, and outputs are open-drain with no internal pull-up. When VCC = 1.8 V, the device safely accepts 5-V inputs and drives external 5-V pull-ups, enabling seamless bidirectional level translation for protocols like I²C - confirmed in the "Input and Open-Drain Output Accepts Voltages up to 5.5 V" feature bullet.
Is the SN74LVC3G07DCUTG4 suitable for automotive applications?
The base SN74LVC3G07DCUTG4 is not AEC-Q200 qualified; however, TI offers the automotive-grade SN74LVC3G07-Q1 variant, which shares identical functionality and pinout but is qualified for –40°C to +125°C operation with enhanced reliability testing. For non-safety-critical automotive body electronics outside ASIL zones, the SN74LVC3G07DCUTG4 may be used subject to system-level qualification - as noted in TI's PACKAGE OPTION ADDENDUM.
