Product details
Overview
SN74AUP3G06RSER from Texas Instruments is a triple inverter buffer/driver with open-drain outputs, designed for ultra-low-power 0.8 V to 3.6 V operation in portable and battery-powered systems. It delivers 4.3 ns maximum propagation delay at 3.3 V, 0.9 mA maximum ICC, and 1.5 pF typical input capacitance - enabling high-speed logic-level translation in point-to-point I²C, SMBus, and GPIO expansion applications.
For engineers reviewing the SN74AUP3G06RSER datasheet, SN74AUP3G06RSER pinout, SN74AUP3G06RSER application, or SN74AUP3G06RSER equivalent, key selection criteria include its open-drain output architecture, Ioff partial-power-down support, 3.6-V I/O tolerance for mixed-voltage interfacing, and UQFN-8 (RSE) package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP3G06RSER implements three independent inverters, each with an open-drain output stage capable of wired-AND or active-low wired-OR bus configurations. Its AUP logic family uses optimized CMOS process design to maintain sub-1 µA static current across the full 0.8–3.6 V VCC range while supporting dynamic switching up to 25 MHz under 15 pF load.
Input thresholds scale with VCC (VIH = 0.65×VCC min at 1.1–1.95 V), and Ioff circuitry actively disables outputs during power-down to prevent backflow current - critical for hot-swap and multi-rail system integrity. The device 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 | 0.8 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V domains without level shifters. |
| tpd (Max) | 3.3 ns at 3.3 V, CL = 15 pF - supports reliable timing in 25-MHz clocked control paths and data strobes. |
| ICC (Max) | 0.9 mA at VCC = 3.6 V - extends battery life in always-on sensor nodes and wearable MCU peripherals. |
| Cpd | 4.3 pF typical at 3.3 V - minimizes dynamic power draw in high-frequency toggle scenarios (e.g., I²C SCL). |
| IOFF Support | Yes - prevents destructive current flow when VCC = 0 V while inputs remain biased, essential for partial-power-down sequencing. |
| Output Type | Open-drain - allows bidirectional bus pull-up sharing, active-low wired-OR arbitration, and voltage-level agnostic signal combining. |
| Input Capacitance | 1.5 pF typical - reduces loading on driving sources and preserves signal edge integrity in fan-out-limited traces. |
Pinout & Package
SN74AUP3G06RSER is packaged in an 8-pin UQFN (RSE) with 0.4 mm pitch, 1.5 mm × 1.5 mm body, and exposed thermal pad. Pin 1 is located at top-left corner (quadrant Q2 per tape orientation), and the package is RoHS-compliant with NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | Inverter 1 input - accepts CMOS-compatible logic levels scaled to VCC; VIH/VIL thresholds track supply voltage. |
| 2 | 2A (Input) | Inverter 2 input - electrically isolated from other inputs; supports independent signal routing or daisy-chained enable logic. |
| 3 | GND | Ground reference - must be connected to system ground plane; serves as return path for all output sink currents. |
| 4 | VCC | Power supply - supplies core logic and output driver; requires local 100-nF decoupling near pin 4. |
| 5 | 1Y (Output) | Inverter 1 open-drain output - sinks current only; requires external pull-up to define high state voltage and rise time. |
| 6 | 3A (Input) | Inverter 3 input - identical electrical characteristics to pins 1 and 2; usable for third independent control path. |
| 7 | 2Y (Output) | Inverter 2 open-drain output - shares no internal connection with 1Y or 3Y; supports separate bus segments. |
| 8 | 3Y (Output) | Inverter 3 open-drain output - enables three independent open-drain drivers in one 1.5 mm × 1.5 mm footprint. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 mA max across full 0.8–3.6 V VCC range - eliminates need for power gating in always-on subsystems. |
| Open-drain outputs | Three independent open-drain outputs support wired-AND bus arbitration, I²C/SMBus compatibility, and mixed-voltage pull-ups. |
| Ioff partial-power-down | Outputs disabled and high-impedance when VCC = 0 V - prevents backfeed into powered sections during hot-swap or rail sequencing. |
| 3.6-V I/O tolerant | Inputs and outputs withstand up to 3.6 V regardless of VCC - enables safe interfacing with higher-voltage controllers without external clamping. |
| NanoStar™/UQFN packaging | 1.5 mm × 1.5 mm RSE package with thermal pad - reduces PCB area by >60% vs. SSOP-8 while improving thermal performance (qJA = 253°C/W). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G06DCUR | Higher ICC (max 10 µA vs. 0.9 mA), wider VCC range (1.65–5.5 V), but no Ioff support. | Lacks partial-power-down protection; unsuitable for hot-swap or multi-rail isolation use cases. | Select when interfacing with 5 V systems and Ioff is not required; avoid where VCC sequencing or rail independence matters. |
| SN74AUP2G06DQER | Dual inverter (2 channels), same AUP family specs, X2SON-6 package (1.05 mm × 1.45 mm). | Reduces channel count by one; smaller footprint but insufficient for three-signal applications like triple-enable sequencing. | Choose only if exactly two inverted open-drain outputs are needed and board space is more constrained than channel count. |
Compared with SN74LVC3G06DCUR, SN74AUP3G06RSER provides 90% lower static current and Ioff safety for power-domain isolation; compared with SN74AUP2G06DQER, it adds a third independent inverter in nearly identical footprint area - making it optimal for compact, multi-signal, battery-sensitive designs.

FAQ
What is the maximum operating frequency supported by SN74AUP3G06RSER?
The SN74AUP3G06RSER is characterized for reliable operation up to 25 MHz under CL = 15 pF load conditions, with 3.3 ns maximum propagation delay at 3.3 V. While not a clocked device, its timing parameters support use in high-speed control paths such as I²C Fast Mode Plus (1 Mbps) and GPIO toggling in real-time sensor interfaces - provided layout parasitics and pull-up strength are optimized per TI's application guidance.
Does SN74AUP3G06RSER require external pull-up resistors on its outputs?
Yes, SN74AUP3G06RSER outputs are open-drain and must be used with external pull-up resistors to define the high logic state. Typical values range from 2.2 kΩ (for 100 kHz I²C) to 10 kΩ (for low-power GPIO), selected based on rise time requirements, bus capacitance, and VCC level. No internal pull-ups are present.
Can SN74AUP3G06RSER operate with a 1.2 V supply?
Yes, SN74AUP3G06RSER is fully specified from 0.8 V to 3.6 V. At 1.2 V, it delivers VIH = 0.78 V (min), VIL = 0.42 V (max), and tpd ≤ 12.8 ns (CL = 5 pF), making it suitable for direct integration with 1.2 V FPGA I/O banks and low-voltage ASIC cores without level translation.
How does the Ioff feature of SN74AUP3G06RSER protect system integrity?
The Ioff circuitry in SN74AUP3G06RSER disables all outputs when VCC = 0 V, placing them in high-impedance state regardless of input voltage. This prevents current backflow from live signal lines into a powered-down section - a critical safeguard during hot-swap events, power-rail sequencing, or partial system sleep modes in multi-voltage architectures.
Is SN74AUP3G06RSER pin-compatible with other packages in the same family?
No - SN74AUP3G06RSER uses the UQFN-8 (RSE) package with specific 1.5 mm × 1.5 mm dimensions and quadrant Q2 pin 1 orientation. While functional equivalents exist in DCU (SSOP-8), DQE (X2SON-8), and YFP (DSBGA-8) packages, their land patterns, thermal pads, and mechanical footprints differ; PCB redesign is required for package substitution.
