Product details
Overview
SN74LVC2G07DCKT from Texas Instruments is a dual open-drain buffer IC designed for level translation and wired-OR logic functions 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 max propagation delay at 3.3 V - enabling robust I²C bus buffering, LED driving, and mixed-voltage interface bridging in portable media players and embedded PCs.
For engineers reviewing the SN74LVC2G07DCKT datasheet, SN74LVC2G07DCKT pinout, SN74LVC2G07DCKT application, or SN74LVC2G07DCKT equivalent, key selection criteria include open-drain drive strength (32 mA), Ioff-enabled live insertion support, 5.5-V input tolerance, and SC70-6 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74LVC2G07DCKT implements two independent non-inverting open-drain buffers, each requiring external pull-up resistors to define high-level output voltage and enable voltage translation across domains. Its Ioff circuitry actively disables outputs during partial power-down, blocking back-current flow when VCC = 0 V.
Input thresholds are VIL ≤ 0.35×VCC and VIH ≥ 0.65×VCC over 1.65–5.5 V supply range; output VOL remains ≤0.55 V at IOL = 32 mA and VCC = 4.5 V. ESD protection meets 2000-V HBM, 1000-V CDM, and 200-V MM standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| Max Sink Current | 32 mA per output at 4.5 V - sufficient for driving LEDs or terminating I²C buses without external drivers |
| Propagation Delay | 3.7 ns max at VCC = 3.3 V - supports >100-MHz signal routing in timing-critical interfaces |
| Input Voltage Tolerance | Up to 5.5 V - allows interfacing with higher-voltage controllers while powered from lower VCC |
| Ioff Current | ±10 μA max - ensures safe live insertion and prevents back-drive damage during hot-swap events |
| ESD Rating | 2000-V HBM - exceeds JEDEC JESD22-A114A for reliable handling in manufacturing environments |
Pinout & Package
SN74LVC2G07DCKT uses the SC70-6 (DCK) package: 2.00 mm × 1.25 mm body, 0.65-mm pitch, 6-pin surface-mount outline with pin 1 in quadrant Q3 per tape-and-reel standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | Non-inverting digital input for first buffer channel; 5.5-V tolerant |
| GND | Ground | Reference return path for all internal circuitry and output sinking current |
| 2A | Input 2 | Non-inverting digital input for second buffer channel; 5.5-V tolerant |
| 2Y | Open-drain output 2 | Sinks current only; requires external pull-up to define logic HIGH voltage |
| VCC | Power supply | Supplies core logic and output stage; range 1.65–5.5 V |
| 1Y | Open-drain output 1 | Sinks current only; enables wired-AND/OR logic when paralleled with other open-drain outputs |
Key Features
| Feature | Design Value |
|---|---|
| Dual open-drain configuration | Enables active-low wired-OR and active-high wired-AND logic without external diodes or transistors |
| 32-mA sink capability at 4.5 V | Drives standard LEDs directly or terminates multiple I²C devices on shared bus lines |
| Ioff partial-power-down support | Prevents damaging back-current flow when VCC is off but inputs remain active - critical for hot-plug systems |
| NanoFree™ SC70 package | Dies-as-package construction reduces footprint to 2.5 mm² - ideal for ultra-compact portable electronics |
| 5.5-V input tolerance | Allows connection to legacy 5-V microcontrollers while operating from modern low-voltage rails (e.g., 1.8 V) |
Applications
| Mobile Phone Interface | Embedded PC I²C Bus Buffer |
|---|---|
Use Scenario: Level-shifting between 1.8-V application processor GPIOs and 3.3-V sensor hub I²C lines. IC Role / Device Role / Timing Role: Dual open-drain buffer providing bidirectional voltage translation and bus isolation. Use Value: Eliminates need for discrete MOSFET translators; 32-mA sink handles up to 10 I²C slaves with standard 2.2-kΩ pull-ups. |
Use Scenario: Isolating and strengthening SMBus alerts from multiple thermal sensors to a 3.3-V host controller. IC Role / Device Role / Timing Role: Wired-OR combiner for interrupt signals with guaranteed VOL ≤ 0.55 V under full load. Use Value: Reduces signal skew vs. passive diode-OR; Ioff prevents backfeed when host powers down mid-operation. |
| Portable Media Player LED Driver | Tablet Power-Sequence Monitor |
Use Scenario: Driving RGB backlight LEDs from 2.5-V MCU PWM outputs with common-anode configuration. IC Role / Device Role / Timing Role: High-current open-drain sink for cathode-side LED control with fast 3.7-ns tpd. Use Value: Replaces discrete N-MOSFETs; 32-mA rating supports 20-mA LEDs with margin for brightness headroom. |
Use Scenario: Monitoring 1.2-V core rail and 3.3-V I/O rail power-good signals before releasing reset to SoC. IC Role / Device Role / Timing Role: Logic-level translator and wired-AND gate combining PG signals into single reset-enable line. Use Value: 5.5-V input tolerance accepts 3.3-V PG signals while powered from 1.2-V rail; eliminates level-shifter IC count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G07DBVR | SOT-23-6 package (2.90 mm × 1.60 mm); same electrical specs and pinout | Larger footprint; better thermal dissipation (RθJA = 165°C/W vs. 259°C/W for DCK) | Select for manual assembly, thermal-limited designs, or legacy board compatibility |
| SN74LVC1G07DCKR | Single-channel version in identical SC70-5 package; no second buffer | Half the channel count; not suitable for dual-signal applications like I²C SDA/SCL buffering | Select only when one open-drain buffer suffices and board area must be minimized beyond dual-channel needs |
Compared with SN74LVC2G07DBVR and SN74LVC1G07DCKR, SN74LVC2G07DCKT uniquely balances ultra-small SC70-6 footprint (2.5 mm²), dual-channel functionality, and full 32-mA sink capability - making it optimal for space-constrained dual-signal translation where thermal limits permit.

Does SN74LVC2G07DCKT support partial power-down operation?
Yes, SN74LVC2G07DCKT includes Ioff circuitry that disables outputs when VCC = 0 V, limiting Ioff to ±10 μA max. This feature prevents damaging back-current flow during live insertion or system power sequencing - explicitly verified in Section 8.1 and Table 6.5 of the SN74LVC2G07 datasheet.
What package type does SN74LVC2G07DCKT use, and what are its dimensions?
SN74LVC2G07DCKT uses the SC70-6 (DCK) package: nominal body size 2.00 mm × 1.25 mm, 0.65-mm lead pitch, and 6-pin surface-mount configuration. This is documented in the Device Information table (page 3) and Packaging Addendum (page 11) of SCES308L Rev L.
Can SN74LVC2G07DCKT interface between 1.8-V and 5-V logic domains?
Yes, SN74LVC2G07DCKT accepts input voltages up to 5.5 V regardless of VCC setting (1.65–5.5 V), enabling reliable level translation both up (e.g., 1.8-V MCU to 3.3-V peripheral) and down (e.g., 5-V sensor to 2.5-V controller). This is specified in Section 6.3 (Recommended Operating Conditions) and Section 8.3 (Feature Description).
Is SN74LVC2G07DCKT pin-compatible with other variants in the SN74LVC2G07 family?
