Product details
Overview
SN74AUC2G07DCKRG4 from Texas Instruments is a dual non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 1.95-V operation in ultra-low-power portable and battery-powered systems. It delivers ±8-mA sink drive at 1.8 V, achieves 2.5-ns max propagation delay, and supports mixed-mode I/O up to 3.6 V while consuming only 10 µA ICC at 1.8 V.
For engineers reviewing the SN74AUC2G07DCKRG4 datasheet, SN74AUC2G07DCKRG4 pinout, SN74AUC2G07DCKRG4 application, or SN74AUC2G07DCKRG4 equivalent, key selection criteria include open-drain logic compatibility, sub-1-V operability, Ioff-enabled partial-power-down support, and SC-70 (DCK) package suitability for space-constrained PCB layouts.
Technical Context
This device implements two independent non-inverting buffers, each with an open-drain output stage capable of wired-OR/AND bus interfacing. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, satisfying JESD 78 Class II latch-up requirements (>100 mA).
Operational across 0.8 V–2.7 V VCC, it is optimized for 1.8-V systems but maintains valid logic thresholds down to 0.8 V (VIH = 0.65×VCC, VIL = 0.35×VCC). Input transition rate tolerance is 20 ns/V, and output sink capability reaches 32 mA absolute maximum - exceeding typical ±8-mA rated drive under standard conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - enables operation in sub-1-V domains and compatibility with 1.8-V core logic |
| Max tPD | 2.5 ns at 1.8 V - supports high-speed signal buffering in timing-critical interfaces |
| IOL Drive | ±8 mA at 1.8 V - sufficient for driving multiple CMOS loads or pull-up resistors on shared buses |
| ICC Quiescent | 10 µA at 1.8 V - minimizes standby power in always-on sensor or communication subsystems |
| Ioff Support | Yes - prevents current backflow when VCC = 0, enabling safe hot-insertion and partial-power-down modes |
| IOH/IOZ | Open-drain output - requires external pull-up; enables level translation and wired-logic bus architectures |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements |
Pinout & Package
SN74AUC2G07DCKRG4 uses the SC-70 (DCK) 6-pin surface-mount package (1.85 mm × 1.40 mm × 1.10 mm max height), optimized for high-density portable PCBs. Pin 1 is marked by a dot or notch orientation in the top-left corner per JEDEC MO-203AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input - accepts 0.8–3.6 V logic signals; compatible with 1.8-V and mixed-voltage domains |
| 2 | GND | Ground reference - must be low-impedance connection to minimize noise coupling into sensitive inputs |
| 3 | 1Y (Output) | Open-drain output of first buffer - requires external pull-up; sinks up to 32 mA max |
| 4 | 2Y (Output) | Open-drain output of second buffer - electrically isolated from 1Y; supports independent bus segments |
| 5 | VCC | Supply rail - powers internal logic; must be decoupled locally with 0.1-µF ceramic capacitor |
| 6 | 2A (Input) | Second buffer input - identical electrical characteristics to Pin 1; supports dual-channel signal conditioning |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ WCSP option available | Die-as-package construction reduces footprint and thermal resistance - not applicable to DCK variant but confirms TI's ultra-miniaturization roadmap |
| 3.6-V I/O tolerance | Allows interface with higher-voltage peripherals without level shifters - critical for mixed-signal SoC interconnects |
| Sub-1-V operability | Functional at 0.8 V VCC - supports emerging ultra-low-power microcontrollers and energy-harvesting systems |
| Latch-up immunity | Exceeds 100 mA per JESD 78 Class II - ensures reliability in noisy industrial or automotive environments |
| Low-input capacitance | Ci = 2.5 pF - minimizes loading on high-impedance source drivers and preserves signal integrity |
Applications
| USB Type-C CC Line Interface | I²C Bus Level Translation |
|---|---|
Use Scenario: Bidirectional signaling between 1.8-V controller and 3.3-V USB PD controller over CC line. IC Role / Device Role / Timing Role: Dual open-drain buffer isolates voltage domains while preserving I²C-compatible timing and pull-up flexibility. Use Value: Eliminates discrete MOSFET translators; leverages 3.6-V I/O tolerance and 2.5-ns tPD to meet USB PD specification rise/fall time limits. | Use Scenario: Interfacing 1.8-V FPGA I/O banks to 3.3-V sensor hub via shared I²C bus. IC Role / Device Role / Timing Role: Acts as bidirectional voltage-tolerant buffer - each channel handles SDA/SCL separately with no direction control needed. Use Value: Enables drop-in replacement of discrete resistor-divider networks; reduces BOM count and layout area while maintaining <500-ps skew between channels. |
| Low-Power Sensor Node Wake-Up Logic | EEPROM Write-Protection Control |
Use Scenario: Enabling wake-up interrupt path from always-on motion sensor to sleep-mode MCU core. IC Role / Device Role / Timing Role: Buffer conditionally pulls MCU interrupt line low using open-drain output; powered only during active sensing phase. Use Value: Ioff support blocks leakage during MCU deep-sleep (<10 µA total system quiescent), extending battery life in multi-year deployments. | Use Scenario: Controlling write-enable pin of serial EEPROM in embedded instrumentation. IC Role / Device Role / Timing Role: Drives EEPROM /WP pin low to enable writes; open-drain allows safe sharing with other controllers via wired-AND. Use Value: 32-mA sink capability ensures reliable low-state assertion even with long PCB traces or capacitive loads (>100 pF). |
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 |
|---|---|---|---|
| SN74LVC2G07DCKR | Higher ICC (10 µA vs. 20 µA typical), wider VCC range (1.65–5.5 V), slower tPD (3.5 ns @ 3.3 V) | Better suited for 3.3-V legacy systems; less optimal for sub-1.8-V operation | Select when 5-V tolerance or broader supply margin is required over ultra-low-power priority |
| NC7WZ07P6X | Lower drive (±8 mA @ 1.8 V same), but higher VOL (0.55 V @ 8 mA), no Ioff support | Lacks partial-power-down protection - unsuitable for hot-swap or multi-rail sequencing | Choose only for cost-sensitive, single-rail 1.8-V designs where Ioff is not mandated |
Compared with SN74LVC2G07DCKR and NC7WZ07P6X, SN74AUC2G07DCKRG4 uniquely combines sub-1-V operation, 10-µA quiescent current, and Ioff - making it the only choice for battery-critical, multi-voltage, and hot-pluggable applications requiring guaranteed power-down isolation.

FAQ
What is the maximum sink current rating for SN74AUC2G07DCKRG4?
The absolute maximum sink current for SN74AUC2G07DCKRG4 is 32 mA per output, as specified in the Absolute Maximum Ratings table. Under recommended operating conditions at 1.8 V, it delivers ±8 mA with VOL ≤ 0.45 V - sufficient for driving standard pull-up resistors on I²C or SMBus lines. Exceeding 32 mA risks permanent damage and violates SOA limits.
Does SN74AUC2G07DCKRG4 support partial-power-down mode?
Yes, SN74AUC2G07DCKRG4 fully supports partial-power-down mode via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables both outputs, limiting input/output leakage to ±10 µA - preventing damaging backflow current from live buses into the unpowered device. This behavior is tested and guaranteed per JESD 78.
Can SN74AUC2G07DCKRG4 operate below 1.0 V?
Yes, SN74AUC2G07DCKRG4 is explicitly characterized down to 0.8 V VCC and is sub-1-V operable. At 0.8 V, VIH = 0 V and VIL = 0 V per datasheet, meaning it functions as a thresholdless buffer - ideal for emerging ultra-low-power microcontrollers and energy-harvesting systems where supply rails dip below 1.0 V during brownout conditions.
What is the SC-70 (DCK) package footprint for SN74AUC2G07DCKRG4?
The SN74AUC2G07DCKRG4 uses the SC-70 (DCK) package: 1.85 mm × 1.40 mm body size, 1.10 mm max height, 0.65 mm pin pitch, and 6 terminals. Land pattern dimensions per TI's DCK0006A drawing specify 0.9 mm × 0.4 mm pads with 0.07 mm solder mask expansion - critical for reliable reflow in fine-pitch automated assembly.
Is SN74AUC2G07DCKRG4 pin-compatible with other variants in the SN74AUC2G07 family?
Yes, SN74AUC2G07DCKRG4 shares identical pinout and functionality with SN74AUC2G07DBVR (SOT-23) and SN74AUC2G07YZPR (DSBGA); all three use the same 6-pin arrangement (1A, GND, 1Y, 2Y, VCC, 2A) and logic behavior. However, thermal performance (θJA = 259°C/W for DCK) and board-level routing constraints differ significantly between packages.
