Product details
Overview
SN74LVC2G07DRYR from Texas Instruments is a dual open-drain buffer IC designed for level translation and wired-OR logic implementation in 1.65-V to 5.5-V systems. It features two independent open-drain outputs capable of sinking up to 32 mA at 4.5 V, supports 5.5-V tolerant inputs, and delivers 3.7 ns max propagation delay at 3.3 V - enabling use in I²C bus buffering, LED driving, and mixed-voltage interface isolation.
For engineers reviewing the SN74LVC2G07DRYR datasheet, SN74LVC2G07DRYR pinout, SN74LVC2G07DRYR application, or SN74LVC2G07DRYR equivalent, key selection criteria include its 6-pin DRY (SON) package footprint, Ioff-enabled partial-power-down capability, 10-μA max ICC quiescent current, and compatibility with both up- and down-translation between 1.8-V, 3.3-V, and 5-V domains.
Technical Context
The SN74LVC2G07DRYR implements two non-inverting open-drain buffers with independent inputs (1A, 2A) and outputs (1Y, 2Y), requiring external pull-up resistors to establish high-level logic states. Its Ioff circuitry actively disables outputs during power-down, blocking back-drive current and supporting live insertion in hot-swap systems.
Input voltage tolerance up to 5.5 V - regardless of VCC setting - enables robust interfacing across voltage domains. 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, 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 families |
| Max Sink Current per Output | 32 mA at 4.5 V - sufficient to drive LEDs directly or terminate I²C/SMBus lines with standard pull-ups |
| Propagation Delay (tpd) | 3.7 ns max at VCC = 3.3 V - enables timing-critical signal buffering in high-speed digital interfaces |
| Ioff Current | ±10 μA max - prevents damaging back-current flow when VCC = 0 V, critical for partial-power-down systems |
| Input Voltage Tolerance | Up to 5.5 V - allows interfacing with higher-voltage controllers without level shifters |
| Quiescent ICC | 10 μA max - minimizes standby power in battery-powered or energy-sensitive applications |
| ESD Rating (HBM) | 2000 V - exceeds JEDEC JS-001 requirements for robust handling in manufacturing and field environments |
Pinout & Package
SN74LVC2G07DRYR uses the 6-pin DRY (SON) package: 1.45 mm × 1.00 mm body, 0.5-mm pitch, bottom-exposed thermal pad, and wettable flank leads for automated optical inspection. Pin 1 is located in Quadrant Q1 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input | Non-inverting input for first buffer channel; 5.5-V tolerant, accepts logic levels independent of VCC |
| GND | Ground | Reference node for all internal circuitry and output sink paths; must be low-impedance for noise control |
| 2A | Input | Non-inverting input for second buffer channel; electrically isolated from 1A, supports independent signal routing |
| 2Y | Open-drain output | Sinks current only; requires external pull-up to define high state; enables wired-AND/OR bus topologies |
| VCC | Power supply | Supplies core logic and I/O structures; range 1.65–5.5 V determines VOL, drive strength, and speed |
| 1Y | Open-drain output | Independent open-drain output; may share pull-up with 2Y for bus arbitration or be pulled to separate voltages |
Key Features
| Feature | Design Value |
|---|---|
| Dual open-drain configuration | Enables independent or shared wired-logic functions (e.g., I²C bidirectional lines or interrupt aggregation) |
| Ioff partial-power-down support | Prevents back-current flow when VCC is off - essential for hot-plug, modular, or multi-rail power architectures |
| 5.5-V input tolerance | Eliminates need for external level translators when interfacing with legacy 5-V microcontrollers or sensors |
| NanoFree™ DRY package | Die-as-package construction reduces size (1.45 mm × 1.00 mm) and thermal resistance (RθJA = 234°C/W) |
| Low dynamic power (Cpd = 4 pF at 5 V) | Minimizes switching noise and supply current surges in high-frequency toggle applications like clock distribution |
Applications
| I²C Bus Buffering | LED Driver Interface |
|---|---|
Use Scenario: Isolating and extending I²C bus segments across PCB sections with different supply domains or noise environments. IC Role / Device Role / Timing Role: Acts as a unidirectional open-drain repeater on SDA/SCL lines, preserving bus timing while breaking ground loops. Use Value: Enables reliable multi-master I²C communication over longer traces or across voltage boundaries (e.g., 3.3-V MCU to 5-V sensor), with no added propagation delay beyond 3.7 ns. |
Use Scenario: Driving discrete LEDs or LED arrays in portable audio docks, tablet indicators, or embedded status panels. IC Role / Device Role / Timing Role: Provides high-current sinking capability (32 mA at 4.5 V) without external transistor stages. Use Value: Reduces BOM count by eliminating discrete MOSFETs; supports PWM dimming via MCU GPIO with fast 3.7-ns edge response. |
| Hot-Swap Signal Isolation | Mixed-Voltage Logic Translation |
Use Scenario: Protecting host controller pins during insertion/removal of daughterboards or peripheral modules in industrial PLCs. IC Role / Device Role / Timing Role: Buffers control/status signals (e.g., RESET#, IRQ) while enforcing Ioff behavior during VCC ramp-up/down. Use Value: Prevents back-driving of powered-down subsystems - eliminates risk of latch-up or supply rail corruption during live insertion. |
Use Scenario: Interfacing 1.8-V FPGA I/O banks with 3.3-V peripherals such as UART transceivers or SPI flash memory. IC Role / Device Role / Timing Role: Translates logic levels bidirectionally using external pull-ups tied to the target domain voltage. Use Value: Supports both up-translation (1.8-V out → 3.3-V bus) and down-translation (3.3-V out → 1.8-V input) without direction control pins. |
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); slightly larger footprint and higher RθJA (259°C/W) | Same electrical specs but less space-constrained; preferred where reflow profile or test access favors SC70 | Select when board layout accommodates larger package or when SC70 is standardized across other LVC2G devices |
| SN74LVC1G07DBVR | Single-channel version in SOT-23-5; lacks second buffer and has different pinout (no GND pin - uses substrate) | Not functionally equivalent for dual-buffer needs; requires two units for same functionality | Choose only if system requires exactly one open-drain buffer and SOT-23-5 placement is mandatory |
Compared with SN74LVC2G07DCKR and SN74LVC1G07DBVR, SN74LVC2G07DRYR offers the smallest footprint (1.45 mm × 1.00 mm), lowest thermal resistance among 6-pin SON variants, and native dual-channel integration - reducing component count and interconnect complexity in space-constrained, thermally demanding designs.

FAQ
What is the maximum sink current supported by each output of the SN74LVC2G07DRYR?
Each output of the SN74LVC2G07DRYR supports up to 32 mA sink current at VCC = 4.5 V while maintaining VOL ≤ 0.55 V. At lower VCC (e.g., 3.0 V), the guaranteed sink current is 16 mA. These values are specified in the Electrical Characteristics table under IOL test conditions and are validated across –40°C to 125°C.
Does the SN74LVC2G07DRYR support level translation between different voltage domains?
Yes, the SN74LVC2G07DRYR supports both up- and down-translation: its inputs tolerate voltages up to 5.5 V regardless of VCC, and its open-drain outputs can be pulled up to any voltage ≤ 5.5 V. For example, with VCC = 1.8 V and a 3.3-V pull-up, it translates 1.8-V logic high to 3.3-V bus high - confirmed in the Functional Description and Application sections of the datasheet.
What is the purpose of the Ioff feature in the SN74LVC2G07DRYR?
The Ioff feature disables output drivers when VCC = 0 V, limiting Ioff current to ±10 μA max. This prevents current backflow from live buses into a powered-down SN74LVC2G07DRYR - protecting downstream circuitry during partial-power-down or hot-swap events. It is explicitly characterized in Section 6.5 and enabled by design across all temperature ranges.
Can the SN74LVC2G07DRYR be used in I²C applications?
Yes, the SN74LVC2G07DRYR is commonly used for I²C bus buffering and isolation. Its open-drain outputs match I²C electrical requirements, and its 5.5-V input tolerance allows direct connection to 5-V masters/slaves. TI's Application Report SBAA342 confirms its suitability for I²C repeater designs, noting that external pull-ups must be sized per bus capacitance and speed class.
What is the thermal resistance (RθJA) of the SN74LVC2G07DRYR in its DRY package?
The SN74LVC2G07DRYR in the DRY (SON) package has a junction-to-ambient thermal resistance (RθJA) of 234°C/W, as specified in Section 6.4 of the datasheet. This value assumes standard JEDEC PCB mounting conditions (2-layer board, 1-in² copper) and is lower than SC70 (259°C/W) and SOT-23 (165°C/W) variants due to the DRY package's enhanced thermal pad exposure.
