Product details
Overview
SN74AUP3G07DCUR from Texas Instruments is a triple non-inverting buffer/driver with open-drain outputs, designed for low-power 0.8 V to 3.6 V operation. It delivers 2.2 ns typical propagation delay at 3.3 V (CL = 15 pF), 0.9 µA maximum ICC, and 1.5 pF typical input capacitance - enabling battery-powered I²C bus extensions, level-shifting interfaces, and wired-AND logic in portable instrumentation.
For engineers reviewing the SN74AUP3G07DCUR datasheet, SN74AUP3G07DCUR pinout, SN74AUP3G07DCUR application, or SN74AUP3G07DCUR equivalent, this page provides verified package mapping (VSSOP-8 DCU), confirmed open-drain output behavior, Ioff partial-power-down support, and validated substitution options for mixed-voltage signal conditioning.
Technical Context
The SN74AUP3G07DCUR implements three independent non-inverting buffers, each with an open-drain output stage capable of sinking up to 20 mA per channel. Its Ioff circuitry actively disables outputs during power-down, preventing backflow current when VCC = 0 V while inputs remain biased at 0–3.6 V.
It operates across a wide VCC range (0.8 V to 3.6 V) with rail-to-rail input tolerance and 3.6-V I/O compatibility, supporting mixed-mode voltage translation without external pull-ups on the output side. Propagation delay scales predictably with load capacitance and supply voltage - e.g., 2.2 ns (typ) at 3.3 V/15 pF, 3.7 ns (typ) at 3.3 V/30 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with sub-1V logic, 1.8V I/O, and 3.3V systems without level shifters. |
| tpd (3.3 V, CL = 15 pF) | 2.2 ns typical - supports >100 MHz signal routing in point-to-point configurations with minimal timing skew. |
| ICC (max) | 0.9 µA at 25°C - extends battery life in always-on sensor nodes and wearable controllers. |
| Ioff (max) | 0.6 µA at 0 V VCC - ensures safe isolation during hot-insertion or partial system power-down. |
| Open-Drain Output | Sinks up to 20 mA per channel - allows wired-AND bus arbitration and I²C-compatible bidirectional signaling. |
| Ci (typ) | 1.5 pF - minimizes capacitive loading on high-speed MCU GPIOs and reduces signal integrity degradation. |
| Cpd (3.3 V) | 4.3 pF - contributes <1 µW dynamic power per transition at 10 MHz, critical for ultra-low-power wake-up paths. |
Pinout & Package
VSSOP-8 (DCU) package: 2.3 mm × 2.0 mm body, 0.5 mm lead pitch, exposed thermal pad, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Input (Buffer A/B/C) | Dedicated logic inputs for each of three independent non-inverting buffers. |
| 1Y, 2Y, 3Y | Open-Drain Output (Buffer A/B/C) | Active-low outputs requiring external pull-up; support wired-OR/AND and I²C-style bus sharing. |
| 4 | GND | Ground reference for all internal circuitry and output sink current return path. |
| 5 | VCC | Primary power supply (0.8–3.6 V); powers internal logic and enables Ioff control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | 0.9 µA max ICC enables multi-year coin-cell operation in maintenance-free IoT endpoints. |
| Wide VCC scalability | Operates from 0.8 V (e.g., energy-harvesting sources) to 3.6 V (standard LDO rails) without re-biasing. |
| Ioff partial-power-down | Prevents damaging back-current flow when VCC = 0 V but inputs float or are driven externally. |
| Low-noise switching | Overshoot/undershoot <10% of VCC - eliminates need for series termination in space-constrained PCBs. |
| 3.6-V I/O tolerant | Accepts 0–3.6 V input signals regardless of VCC setting - simplifies mixed-voltage interconnect design. |
Applications
| Industrial Sensor Interface | I²C Bus Extension |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G07DCUR | Higher ICC (10 µA typ), faster tpd (1.7 ns @ 3.3 V), but no Ioff or sub-1V operation. | Better for speed-critical 3.3 V-only systems; unsuitable for partial-power-down or energy-harvesting designs. | Choose SN74LVC3G07DCUR only if VCC ≥ 1.65 V and Ioff is not required. |
| SN74AUP2G07DCUR | Dual-channel version (2 buffers), identical electrical specs, same DCU package footprint. | Reduces component count when only two buffered open-drain outputs are needed. | Select SN74AUP2G07DCUR to save board area and BOM line items in dual-signal applications. |
Compared with SN74LVC3G07DCUR, the SN74AUP3G07DCUR offers 11× lower static current and true 0.8 V operation - essential for battery longevity and ultra-low-voltage systems; versus SN74AUP2G07DCUR, it adds a third buffer channel without increasing package size or thermal resistance.

FAQ
What is the maximum output sink current for SN74AUP3G07DCUR?
The SN74AUP3G07DCUR supports up to 20 mA continuous sink current per open-drain output (1Y, 2Y, or 3Y) under recommended operating conditions. This rating holds across the full VCC range (0.8 V to 3.6 V) and ambient temperature (–40°C to 85°C), enabling direct drive of LEDs, small relays, or bus termination networks without external transistors.
Does SN74AUP3G07DCUR support partial-power-down mode?
Yes, SN74AUP3G07DCUR features integrated Ioff circuitry that disables all outputs when VCC = 0 V, limiting Ioff to 0.6 µA maximum. This prevents damaging back-current flow from live inputs into the powered-down device - a critical capability for hot-swap interfaces, modular systems, and energy-harvesting nodes where subsystems power up/down independently.
Can SN74AUP3G07DCUR be used as an I²C bus extender?
Yes, SN74AUP3G07DCUR is commonly deployed as an I²C bus extender due to its open-drain outputs, 3.6-V input tolerance, and low propagation delay (2.2 ns typ at 3.3 V). When configured with appropriate pull-up resistors on SDA/SCL, it isolates bus segments while preserving timing margins - especially valuable in multi-drop industrial sensor networks exceeding standard 400 pF bus capacitance limits.
What is the input capacitance of SN74AUP3G07DCUR and why does it matter?
SN74AUP3G07DCUR has a typical input capacitance (Ci) of 1.5 pF. This low value minimizes loading on driving GPIOs - particularly important for high-impedance or slew-rate-limited sources like RC-filtered wake-up signals or capacitive touch controllers. It also preserves signal integrity in dense layouts where trace capacitance must be tightly controlled to meet setup/hold timing.
Is SN74AUP3G07DCUR pin-compatible with other 8-pin logic devices in VSSOP?
SN74AUP3G07DCUR uses the standard VSSOP-8 (DCU) footprint defined by TI's DCU0008A outline, matching mechanical dimensions and pin 1 orientation (Q3 quadrant) of SN74LVC3G07DCUR and SN74AUP2G07DCUR. However, functional compatibility requires verification of Ioff support, VCC range, and output structure - not all VSSOP-8 logic devices share these characteristics.
