Product details
Overview
SN74LVC3G07DCURG4 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 SN74LVC3G07DCURG4 datasheet, SN74LVC3G07DCURG4 pinout, SN74LVC3G07DCURG4 application, or SN74LVC3G07DCURG4 equivalent, key selection considerations include open-drain output compatibility, 8-pin VSSOP (DCU) package footprint, Ioff-enabled live insertion support, and 32-mA maximum sink current capability at 4.5 V.
Technical Context
This device implements three independent non-inverting buffer stages, each with an open-drain output requiring external pull-up. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, enabling safe hot-plug operation. Input tolerance extends to 5.5 V regardless of VCC, supporting mixed-voltage interfacing.
The logic function is strictly non-inverting (A → Y), with no internal inversion or enable control. All inputs accept voltages up to 5.5 V, and outputs are rated for 6.5 V absolute maximum voltage in high-impedance or powered-off states - critical for robust system-level signal integrity in multi-rail environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| Max tpd | 3.7 ns at 3.3 V - ensures timing-critical signal buffering with minimal latency in high-speed digital interfaces |
| IOL Max | 32 mA at 4.5 V - supports driving heavy capacitive loads or multiple parallel inputs via external pull-up |
| Ioff Current | ±10 μA max - guarantees isolation between powered and unpowered sections in partial-power-down systems |

Pinout & Package
VSSOP (DCU) 8-pin package: 2.3 mm × 2.0 mm body, 0.5-mm pitch, 0.9-mm max height, exposed pad not present, RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input - accepts 1.65–5.5 V logic levels; no internal pull-up/pull-down |
| 2 | GND | Ground reference for all logic and output stages - must be low-impedance for stable VOL performance |
| 3 | 1Y (Output) | Open-drain output for first buffer - requires external pull-up resistor to define high state |
| 4 | 2A (Input) | Second buffer input - electrically isolated from other inputs; same voltage tolerance as Pin 1 |
| 5 | 2Y (Output) | Open-drain output for second buffer - independently controllable; shares no internal nodes with other outputs |
| 6 | VCC | Supply rail for internal logic - powers input buffers and Ioff circuitry; decoupling capacitor required near Pin 6 |
| 7 | 3A (Input) | Third buffer input - identical electrical characteristics to Pins 1 and 4; supports asynchronous signal routing |
| 8 | 3Y (Output) | Open-drain output for third buffer - capable of 32-mA sink at 4.5 V; compatible with I²C, SMBus, and GPIO wake lines |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain outputs | Enable wired-OR logic, I²C/SMBus bus arbitration, and flexible pull-up voltage selection (e.g., 3.3 V pull-up with 1.8 V VCC) |
| Ioff partial-power-down | Prevents current backflow when VCC = 0 V, allowing safe insertion into live backplanes or hot-swap modules |
| 5.5-V tolerant inputs | Eliminates need for external level shifters when interfacing with legacy 5-V peripherals or microcontrollers |
| NanoFree™ packaging | Diesize-as-package construction reduces parasitic inductance and improves thermal resistance vs. conventional SOIC or SSOP |
| Low ICC | 10-μA max quiescent current enables use in battery-backed or ultra-low-power always-on monitoring circuits |
Applications
| Level-Shifting Interface | I²C Bus Extender |

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 but reduced channel count | Suitable only when one open-drain buffer is needed; occupies less board area but increases component count for triple-function needs | Select SN74LVC1G07DBVR if layout space is constrained and channel count can be distributed across multiple ICs |
| SN74AUP3G07DCUR | Same 3-channel open-drain topology but AUP family: lower ICC (500 nA), slower tpd (6.1 ns @ 3.3 V), wider VCC range (0.8–3.6 V) | Better for ultra-low-power always-on monitoring; unsuitable for 5-V tolerant interfaces or >3.6-V operation | Choose SN74AUP3G07DCUR only for battery-powered systems requiring sub-μA standby current and no 5-V signal handling |
Compared with SN74LVC3G07DCURG4, SN74LVC1G07DBVR trades integration for footprint reduction, while SN74AUP3G07DCUR sacrifices speed and voltage range for nanowatt-level quiescent power - neither offers pin-to-pin compatibility or identical functional scope.

FAQ
What is the maximum sink current capability of the SN74LVC3G07DCURG4 at 5-V VCC?
The SN74LVC3G07DCURG4 supports up to 32 mA sink current per output at VCC = 4.5 V. At exactly 5 V, the datasheet specifies IOL = 32 mA as the maximum under recommended operating conditions; no higher value is guaranteed. This rating ensures reliable drive into standard 1-kΩ pull-ups or multiple CMOS inputs while maintaining VOL ≤ 0.75 V.
Does the SN74LVC3G07DCURG4 require external pull-up resistors on its outputs?
Yes, the SN74LVC3G07DCURG4 has open-drain outputs and cannot drive a logic-high state internally. Each output (1Y, 2Y, 3Y) must be connected to an external pull-up resistor tied to a defined voltage rail (e.g., 3.3 V or 5 V). The resistor value is selected based on rise time, bus capacitance, and sink current - typically 1 kΩ to 10 kΩ for I²C or general-purpose use.
Can the SN74LVC3G07DCURG4 be used in a 5-V system with 1.8-V VCC?
Yes, the SN74LVC3G07DCURG4 supports 5.5-V tolerant inputs and operates with VCC as low as 1.65 V. When VCC = 1.8 V, inputs may swing up to 5.5 V, enabling direct connection to 5-V peripherals without level shifters. However, output high level is determined solely by the external pull-up voltage, not VCC - so 5-V logic-high is fully achievable even with 1.8-V supply.
Is the SN74LVC3G07DCURG4 pin-compatible with other packages in the same family?
No, the SN74LVC3G07DCURG4 uses the VSSOP (DCU) 8-pin package, which has different pad layout, pitch (0.5 mm), and dimensions than the SSOP (DCT) or DSBGA (YZP) variants. While all share identical logic functionality and pin numbering, mechanical mounting and solder stencil design differ - PCB layout must match DCU-specific land patterns per TI's DCU0008A outline.
What does the "G4" suffix indicate in SN74LVC3G07DCURG4?
The "G4" suffix denotes TI's green packaging standard: lead-free (Pb-free), RoHS-compliant, and halogen-free construction. It confirms compliance with JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), peak reflow temperature of 260°C, and NiPdAu terminal finish - critical for modern automated assembly and environmental regulatory alignment.
