Product details
Overview
SN74LVC2G07DSFR from Texas Instruments is a dual open-drain buffer IC designed for level translation and wired-OR logic in 1.65-V to 5.5-V systems. It delivers 32-mA sink current per output at 4.5 V, supports 5.5-V tolerant inputs, and achieves 3.7-ns propagation delay at 3.3 V - enabling robust I²C bus buffering, LED driving, and mixed-voltage interface isolation in portable and embedded applications.
For engineers reviewing the SN74LVC2G07DSFR datasheet, SN74LVC2G07DSFR pinout, SN74LVC2G07DSFR application, or SN74LVC2G07DSFR equivalent, key selection criteria include open-drain drive strength, Ioff-enabled partial-power-down capability, NanoFree™ DSF package footprint, and verified 5.5-V input tolerance across full temperature range (–40°C to 125°C).
Technical Context
The SN74LVC2G07DSFR implements two independent open-drain buffers with no internal pullups - requiring external resistors to define high-level voltage and enable bidirectional level translation. Its Ioff circuitry actively disables outputs during power-down, blocking back-drive current and supporting live insertion in hot-swap systems.
Each channel operates with rail-to-rail input tolerance (0–5.5 V), independent of VCC, and sinks up to 32 mA while maintaining VOL ≤ 0.55 V at 4.5 V. Propagation delay remains stable across –40°C to 125°C, with tpd ≤ 4.2 ns at 3.3 V and ≤ 3.4 ns at 5 V under worst-case conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct integration into 1.8-V, 2.5-V, 3.3-V, and 5-V domains without level shifters. |
| Max Sink Current | 32 mA per output at 4.5 V - sufficient to drive LEDs, MOSFET gates, or multiple CMOS inputs in wired-OR configurations. |
| Input Voltage Tolerance | 0 V to 5.5 V regardless of VCC - allows interfacing with higher-voltage controllers while powered from lower VCC rails. |
| tpd (3.3 V) | 3.7 ns max at TA = –40°C to 85°C - ensures timing-critical signal buffering in high-speed digital interfaces. |
| Ioff Leakage | ±10 μA max at VI/VO = 5.5 V - guarantees safe isolation during partial power-down without damaging back-current. |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial-grade robustness requirements for board-level handling and operation. |
| Operating Temp | –40°C to 125°C - qualified for automotive under-hood, industrial control, and extended-temperature embedded use. |
Pinout & Package
SN74LVC2G07DSFR uses the DSF (Dual-Side Flat) SON package: 1.00 mm × 1.00 mm, 6-pin, bottom-exposed thermal pad, moisture sensitivity level 1 (260°C reflow compatible). Pin 1 is located in Quadrant Q2 per TI tape-and-reel specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | CMOS-compatible digital input; 5.5-V tolerant, accepts logic high ≥ 0.7×VCC or up to 5.5 V independently. |
| GND | Ground | Reference return path for all signals and power; must be low-impedance connection to system ground plane. |
| 2A | Input 2 | Independent second input; electrically isolated from 1A but shares same VCC and GND references. |
| 2Y | Open-drain output 2 | Sinks current only; requires external pullup to define VOH; supports wired-AND/OR logic with other open-drain devices. |
| VCC | Power supply | Supplies internal logic; sets output low threshold (VOL); does not constrain input voltage range (VI up to 5.5 V). |
| 1Y | Open-drain output 1 | Functionally identical to 2Y; may be used for separate signal paths or paralleled with 2Y for increased sink capacity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual open-drain configuration | Enables active-low wired-OR and active-high wired-AND bus topologies without external logic gates. |
| Ioff partial-power-down protection | Prevents destructive back-current flow when VCC = 0 V, supporting hot-plug and power-gating architectures. |
| NanoFree™ DSF package | Die-as-package construction reduces footprint to 1.0 mm² and eliminates bond wires - improving thermal performance and reliability. |
| 5.5-V input tolerance | Allows direct connection to legacy 5-V microcontrollers or sensors while operating from modern 1.8-V or 3.3-V supplies. |
| Low ICC (10 μA max) | Minimizes quiescent power in always-on subsystems such as battery-backed real-time clocks or sensor wake-up circuits. |
Applications
| I²C Bus Level Translation | LED Driver Interface |
|---|---|
Use Scenario: Interfacing a 3.3-V microcontroller I²C master with 5-V peripheral slaves using standard pullup resistors on SDA/SCL lines.

IC Role / Device Role / Timing Role: Bidirectional level translator with rail-independent inputs and programmable output pullup voltage. Use Value: Supports both up-translation (1.8 V → 5 V) and down-translation (5 V → 1.8 V) using single external resistor per output. |
Use Scenario: Conditioning status signals in a field-replaceable module where power sequencing must prevent backfeeding. IC Role / Device Role / Timing Role: Ioff-enabled buffer ensuring signal integrity during insertion/removal while main system remains powered.

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G07DCKR | SC70-6 package (2.00 mm × 1.25 mm); 259°C/W RθJA vs. DSF's 300°C/W; identical electrical specs. | Larger footprint but higher thermal mass; preferred for manual assembly or prototyping with standard pick-and-place feeders. | Select DCKR when board space permits larger package and thermal design prioritizes steady-state dissipation over minimal area. |
| SN74LVC2G07DBVR | SOT-23-6 package (2.90 mm × 1.60 mm); 165°C/W RθJA; same pinout but longer lead form factor. | Compatible with legacy SOT-23 footprints; easier hand-soldering and in-circuit probing than DSF or SC70. | Choose DBVR for cost-sensitive production where thermal margin exists and PCB layout accommodates larger outline. |
Compared with SN74LVC2G07DCKR and SN74LVC2G07DBVR, the SN74LVC2G07DSFR offers the smallest footprint (1.0 mm²) and highest board-density efficiency, though with slightly reduced thermal performance - making it optimal for space-constrained portable and wearable electronics where layout area is premium.

FAQ
What is the maximum sink current supported by SN74LVC2G07DSFR at 3.3 V?
The SN74LVC2G07DSFR supports up to 24 mA sink current per output at 3.3 V while maintaining VOL ≤ 0.55 V, as specified in the Electrical Characteristics table under IOL = 24 mA condition. This value is measured across –40°C to 85°C and reflects guaranteed performance for robust wired-OR bus implementations.
Does SN74LVC2G07DSFR require external pullup resistors on its outputs?
Yes, SN74LVC2G07DSFR has open-drain outputs and cannot drive high - external pullup resistors are mandatory to establish VOH. The resistor value determines rise time and power consumption; typical values range from 1 kΩ (fast edges, higher current) to 10 kΩ (low power, slower edges) depending on bus capacitance and speed requirements.
Can SN74LVC2G07DSFR operate with VCC disconnected while inputs remain active?
Yes - the Ioff feature of SN74LVC2G07DSFR actively disables outputs when VCC = 0 V, limiting input/output leakage to ±10 μA. This prevents damaging back-current from live inputs into a powered-down system, making SN74LVC2G07DSFR suitable for partial-power-down and hot-swap applications.
What is the thermal resistance (RθJA) of SN74LVC2G07DSFR in its DSF package?
The SN74LVC2G07DSFR in the DSF (SON) 6-pin package has a junction-to-ambient thermal resistance of 300°C/W, as documented in Section 6.4 of the datasheet. This value assumes standard JEDEC high-K board conditions and informs thermal design margins for continuous 32-mA sink operation at elevated ambient temperatures.
Is SN74LVC2G07DSFR pin-compatible with other packages in the SN74LVC2G07 family?
No - SN74LVC2G07DSFR uses the DSF (1.00 mm × 1.00 mm) SON package with unique pin 1 quadrant (Q2) and land pattern. While functionally identical to SN74LVC2G07DBVR (SOT-23) and SN74LVC2G07DCKR (SC70), it is not mechanically or solder-reflow compatible due to different pad layouts, dimensions, and thermal pad requirements.
