Product details
Overview
SN74AUP3G07RSER from Texas Instruments is a triple non-inverting buffer/driver with open-drain outputs, designed for low-power point-to-point logic interfacing in battery-powered systems. It operates across 0.8 V to 3.6 V, delivers 2.2 ns typical propagation delay at 3.3 V (CL = 15 pF), consumes ≤0.9 µA static current, and supports Ioff partial-power-down mode.
For engineers reviewing the SN74AUP3G07RSER datasheet, SN74AUP3G07RSER pinout, SN74AUP3G07RSER application, or SN74AUP3G07RSER equivalent, this page provides verified electrical specs, RSE-package terminal mapping, real-world use cases in level-shifting and wired-AND bus interfaces, and validated alternative options for supply continuity planning.
Technical Context
The SN74AUP3G07RSER implements three independent non-inverting buffers, each with an open-drain output stage enabling active-low wired-OR or active-high wired-AND logic when connected to external pull-ups. Its AUP-family architecture uses optimized CMOS design to minimize both static (ICC ≤ 0.9 µA) and dynamic (Cpd = 4.3 pF typ at 3.3 V) power consumption.
It features Ioff circuitry that disables outputs during power-down to prevent backflow current, supports 3.6-V I/O tolerance for mixed-voltage signal translation, and maintains low input capacitance (Ci = 1.5 pF typ) and excellent signal integrity with <10% VCC overshoot/undershoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables single-supply operation across ultra-low-voltage microcontrollers and mixed-voltage I²C/SPI buses. |
| tpd (Max) | 2.8 ns at 3.3 V, CL = 15 pF - ensures timing-critical signal buffering without introducing significant latency in high-speed digital control paths. |
| ICC (Max) | 0.9 µA at TA = 25°C - extends battery life in portable medical sensors and wearables by minimizing quiescent current draw. |
| Ioff Support | Yes - prevents damaging current flow during partial power-down, critical for hot-swap and multi-rail system reliability. |
| Open-Drain Outputs | Three independent Y outputs - allows direct implementation of wired-AND logic and level translation without external components. |
| Input Capacitance | 1.5 pF typical - reduces loading on preceding drivers and preserves signal edge rates in high-frequency clock distribution. |
Pinout & Package
SN74AUP3G07RSER is packaged in an 8-pin UQFN (RSE) with 0.4 mm pitch, 1.55 mm × 1.55 mm body, and exposed thermal pad. Pin 1 is located at top-left corner (quadrant Q2 per tape orientation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input - accepts logic-level signals from MCU GPIO or sensor interface. |
| 2 | 2A (Input) | Second buffer input - independently controlled; no internal coupling to other inputs. |
| 3 | GND | Ground reference - must be connected to system ground plane for stable noise margin and thermal dissipation. |
| 4 | 3A (Input) | Third buffer input - enables compact triple-buffering in space-constrained PCB layouts. |
| 5 | VCC | Supply voltage - powers all three buffers; decoupling capacitor required within 2 mm of this pin. |
| 6 | 1Y (Output) | Open-drain output - requires external pull-up to define high state; sinks up to 20 mA. |
| 7 | 2Y (Output) | Open-drain output - electrically isolated from 1Y and 3Y; supports independent bus segments. |
| 8 | 3Y (Output) | Open-drain output - enables three-wire wired-AND configuration with shared pull-up resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA max - eliminates standby current concerns in always-on IoT edge nodes. |
| 3.6-V tolerant I/O | Supports mixed-voltage signaling between 1.8-V logic and 3.3-V peripherals without level shifters. |
| Open-drain flexibility | Enables bidirectional bus arbitration and wired-logic functions in I²C-compatible designs. |
| Ioff protection | Prevents back-current during power sequencing - essential for FPGA configuration and modular power domains. |
| NanoStar™ packaging option | Not applicable to SN74AUP3G07RSER - this RSE variant uses standard UQFN, not DSBGA (YFP). |
Applications
| Level-Shifting Interface | I²C Bus Expansion |
|---|---|
Use Scenario: Translating 1.8-V GPIO outputs to drive 3.3-V LED indicators or optocouplers in mixed-voltage industrial controllers.

IC Role / Device Role / Timing Role: Isolated gate driver with fail-safe Ioff behavior during module insertion/removal. Use Value: Prevents backfeed into powered-down modules; 3.6-V I/O tolerance accommodates legacy 3.3-V control rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G07RSER | Higher ICC (10 µA typ), faster tpd (1.9 ns @ 3.3 V), no Ioff support | Suitable for speed-critical but non-power-sensitive applications; lacks partial-power-down safety | Select when propagation delay dominates over quiescent current; verify system-level power-down sequencing. |
| SN74AUP2G07DQER | Dual-channel (not triple), same AUP family specs, X2SON (DQE) 8-pin package | Used where only two buffered outputs are needed; smaller footprint but reduced channel count | Choose for space-constrained dual-output needs; not a functional replacement for triple-buffer requirement. |
Compared with SN74LVC3G07RSER, SN74AUP3G07RSER trades ~2.5× higher speed for ~11× lower static current and adds Ioff protection-critical for battery longevity and hot-swap robustness. Against SN74AUP2G07DQER, it provides one additional buffer channel in identical low-power envelope but uses RSE instead of DQE packaging.

FAQ
What is the maximum recommended load capacitance for SN74AUP3G07RSER to maintain specified tpd?
The SN74AUP3G07RSER is characterized up to CL = 30 pF, with tpd = 6.3 ns (max) at 3.3 V. For guaranteed 2.8 ns max propagation delay, CL must be ≤15 pF per output. Exceeding 30 pF may degrade timing margins and increase power dissipation; layout parasitics should be included in total CL calculation for SN74AUP3G07RSER.
Does SN74AUP3G07RSER support true bidirectional data transfer like I²C?
No - SN74AUP3G07RSER is a unidirectional buffer with three independent non-inverting open-drain outputs. While its outputs can be wire-OR'd to implement bidirectional bus arbitration (e.g., I²C SDA), the device itself has no internal direction control or data path reversal; external master logic must manage signal flow for SN74AUP3G07RSER-based interfaces.
Can SN74AUP3G07RSER operate reliably at 0.8 V supply with full logic functionality?
Yes - SN74AUP3G07RSER is fully specified from 0.8 V to 3.6 V. At 0.8 V, VOL ≤ 0.1 V (IOL = 20 µA), VIH = 0.65 × VCC = 0.52 V, and tpd ≤ 12.2 ns (CL = 5 pF). All DC and AC parameters remain valid across this range, making SN74AUP3G07RSER suitable for sub-1-V energy-harvesting systems.
Is the exposed thermal pad on the RSE package of SN74AUP3G07RSER required to be soldered?
Yes - the exposed pad on SN74AUP3G07RSER's UQFN (RSE) package must be soldered to a PCB thermal pad for mechanical stability and optimal thermal performance. TI recommends connecting it to GND for EMI reduction and thermal conduction; insufficient solder coverage risks delamination and increased junction temperature during sustained 20-mA output sinking.
How does the Ioff feature of SN74AUP3G07RSER behave when VCC = 0 V but inputs are pulled high?
When VCC = 0 V, the Ioff circuitry actively disables all outputs and isolates inputs, limiting II/OFF to ≤0.6 µA even if inputs are held at 3.6 V. This prevents current backflow into a powered-down domain - a key reliability feature confirmed in SN74AUP3G07RSER's datasheet Section 6.5 (Ioff parameter test conditions).
