Product details
Overview
SN74AUC2G07DCKRE4 from Texas Instruments is a dual non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 1.95-V operation and 3.6-V I/O tolerant interfaces. It delivers ±8-mA sink/source drive at 1.8 V, achieves 2.5 ns max propagation delay, consumes only 10 µA ICC, and supports partial-power-down via Ioff. It is used in level-shifting, wired-AND logic, and bus interface applications in portable and low-voltage embedded systems.
For engineers reviewing the SN74AUC2G07DCKRE4 datasheet, SN74AUC2G07DCKRE4 pinout, SN74AUC2G07DCKRE4 application, or SN74AUC2G07DCKRE4 equivalent, key selection criteria include open-drain output compatibility, sub-1-V operability, 1.8-V optimized timing, Ioff-enabled power sequencing, and SC-70 (DCK) package footprint constraints.
Technical Context
This device implements two independent non-inverting buffers with open-drain outputs, enabling active-low wired-OR or active-high wired-AND configurations when multiple outputs share a common pull-up. Each channel operates across 0.8 V to 2.7 V VCC but is characterized and optimized for 1.65–1.95 V supply range.
It integrates Ioff circuitry that disables outputs during partial power-down, preventing backflow current when VCC = 0 V while inputs remain biased. Input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC), and ESD protection exceeds 2000-V HBM, 200-V MM, and 1000-V CDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V; fully functional down to sub-1-V, enabling ultra-low-power system integration. |
| Max tpd | 2.5 ns at 1.8 V, CL = 15 pF; ensures high-speed signal buffering in compact timing-critical paths. |
| IOL Drive | ±8 mA at 1.8 V; sufficient sink strength to drive standard 1.8-V logic loads and external pull-ups. |
| ICC | 10 µA typical at 1.8 V; minimizes quiescent power in always-on or battery-backed subsystems. |
| Ioff Support | Enabled; blocks current flow between powered/unpowered domains, critical for hot-plug and multi-rail sequencing. |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM; meets industrial handling and board-level robustness requirements. |
| IO Max Sink | 32 mA absolute maximum; allows safe overdrive margin for transient load conditions. |
Pinout & Package
SN74AUC2G07DCKRE4 is housed in a 6-pin SC-70 (DCK) package - 2.0 mm × 1.25 mm, 1.1 mm max height, lead-free NiPdAu finish, MSL Level-1. Pin 1 is marked by a dot in quadrant Q3 of the tape reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input; accepts CMOS-compatible logic levels referenced to local VCC. |
| 2 | GND | Ground reference for both buffers and internal circuitry; must be low-impedance. |
| 3 | 1Y (Output) | Open-drain output of first buffer; requires external pull-up for logic HIGH assertion. |
| 4 | 2Y (Output) | Open-drain output of second buffer; electrically isolated from 1Y but shares same VCC/GND. |
| 5 | VCC | Supply voltage input; powers internal logic and defines VIH/VIL thresholds. |
| 6 | 2A (Input) | Second buffer input; functionally identical and independent of 1A. |
Key Features
| Feature | Design Value |

| Sub-1-V operability | Functional at 0.8 V VCC, supporting next-generation ultra-low-power microcontrollers and energy-harvesting systems. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II, ensuring robustness against transient supply faults and ESD-induced latch-up. |
| Wired-AND capability | Open-drain outputs enable direct connection to shared bus lines with external pull-up, reducing component count in control signaling. |
Applications
| USB OTG Power Switch Control | Low-Power Sensor Interface Bus |
|---|---|
Use Scenario: Managing VBUS enable/disable in USB On-The-Go host-peripheral negotiation using GPIO-controlled open-drain signaling. IC Role / Device Role / Timing Role: Dual buffer isolates MCU GPIOs from bus voltage domains and provides robust 1.8-V–compatible wired-AND handshake signaling. Use Value: Eliminates discrete MOSFET level shifters; leverages Ioff to prevent backfeed during USB suspend states. | Use Scenario: Aggregating interrupt signals from multiple ultra-low-power sensors (e.g., accelerometers, temperature ICs) onto a shared MCU interrupt line. IC Role / Device Role / Timing Role: Open-drain outputs implement active-low wired-OR interrupt bus; sub-1-V operation matches sensor sleep-mode supplies. Use Value: Reduces BOM count and PCB area versus discrete diode-OR networks; maintains timing integrity with 2.5 ns tpd. |
| I²C Bus Voltage Translation | Hot-Swappable Module Detection |
Use Scenario: Translating 1.8-V controller-side I²C signals to 3.3-V peripheral-side bus while maintaining bidirectional SDA/SCL compatibility. IC Role / Device Role / Timing Role: Acts as unidirectional buffer on SCL/SDA lines; 3.6-V I/O tolerance enables safe connection to 3.3-V pull-ups. Use Value: Avoids dedicated bidirectional translators; preserves I²C timing margins due to low tpd and capacitive loading (Ci = 2.5 pF). | Use Scenario: Detecting insertion/removal of field-replaceable modules in telecom or industrial backplanes where main power remains active. IC Role / Device Role / Timing Role: Buffers module-present sense signals into MCU; Ioff prevents leakage when module is unpowered. Use Value: Enables safe hot-swap detection without risk of backfeeding into unpowered modules or damaging sense circuitry. |
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 VCC min (1.65 V), lower drive (±24 mA @ 3.3 V), no sub-1-V operation. | Optimized for 3.3-V systems; lacks 0.8-V functionality and NanoFree packaging. | Select when operating strictly at 3.3 V and cost sensitivity outweighs footprint or ultra-low-VCC needs. |
| NC7SZ07P5X | Single-channel, smaller SC-70-5 package, 3.6-V tolerant, but no Ioff support. | Requires two devices for dual-channel use; unsuitable for partial-power-down architectures. | Choose for space-constrained single-buffer roles where Ioff is not required and layout density is paramount. |
Compared with SN74LVC2G07DCKR and NC7SZ07P5X, SN74AUC2G07DCKRE4 uniquely combines sub-1-V operation, Ioff, NanoFree packaging, and dual-channel open-drain buffering in a single SC-70-6 footprint-making it optimal for next-gen portable and multi-rail embedded designs requiring robust power sequencing and minimal board area.

FAQ
What is the minimum operating voltage for SN74AUC2G07DCKRE4?
The SN74AUC2G07DCKRE4 operates down to 0.8 V VCC, with full functionality including logic threshold tracking and specified timing. This sub-1-V capability is confirmed in the Recommended Operating Conditions table and enables use with emerging ultra-low-power MCUs and energy-harvesting sources. The SN74AUC2G07DCKRE4 maintains reliable performance across its entire 0.8–2.7 V range, though characterization focuses on 1.65–1.95 V.
Does SN74AUC2G07DCKRE4 support hot-swap or partial-power-down operation?
Yes, SN74AUC2G07DCKRE4 includes Ioff circuitry that actively disables outputs when VCC = 0 V, preventing damaging current backflow from live inputs or outputs into the unpowered device. This feature is explicitly verified in the datasheet's "Ioff Supports Partial-Power-Down Mode" bullet and electrical characteristics table (Ioff ≤ ±10 µA), making SN74AUC2G07DCKRE4 suitable for hot-plug and multi-rail sequencing applications.
Can SN74AUC2G07DCKRE4 outputs be wire-OR'd together?
Yes, SN74AUC2G07DCKRE4 features open-drain outputs (1Y and 2Y) that can be directly connected to a common bus with an external pull-up resistor to implement active-low wired-OR or active-high wired-AND logic. The datasheet confirms this capability in the description ("can be connected to other open-drain outputs") and specifies a maximum sink current of 32 mA, providing design margin for shared-bus implementations.
What is the propagation delay of SN74AUC2G07DCKRE4 at 1.8 V?
At VCC = 1.8 V, CL = 15 pF, and TA = 25°C, the SN74AUC2G07DCKRE4 has a maximum tPLH of 2.5 ns and tPHL of 1.9 ns. These values are specified in the Switching Characteristics table and reflect worst-case performance under standard test conditions. The typical propagation delay is lower (1.8 ns tPLH / 1.5 ns tPHL), confirming SN74AUC2G07DCKRE4's suitability for high-speed 1.8-V interface buffering.
