Product details
Overview
SN74AUP2G125YFPR from Texas Instruments is a dual 3-state bus buffer gate optimized for ultra-low-power operation across 0.8 V to 3.6 V supply rails, featuring 5.4 ns max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and Ioff support for partial-power-down mode - deployed in battery-powered portable electronics, sensor interface buses, and low-voltage logic level translation.
For engineers reviewing the SN74AUP2G125YFPR datasheet, SN74AUP2G125YFPR pinout, SN74AUP2G125YFPR application, or SN74AUP2G125YFPR equivalent, key selection criteria include its 0.8–3.6 V VCC range, 3-state output control per channel, NanoStar™ DSBGA-8 (YFP) package with 0.23-mm solder bumps, and verified Ioff performance enabling safe back-drive prevention during power sequencing.
Technical Context
This device implements two independent noninverting buffer channels, each with dedicated output-enable (OE) control and 3-state output capability. Its AUP-family architecture delivers sub-1 µA static ICC at 3.3 V and supports mixed-mode signal operation via 3.6-V-tolerant I/Os, enabling interoperability between 1.2-V, 1.8-V, 2.5-V, and 3.3-V domains without level shifters.
The input-disable feature allows floating inputs without leakage-induced state instability, while hysteresis on inputs improves noise immunity for slow-rising signals. The Ioff circuitry actively disables outputs when VCC = 0 V, blocking current flow from powered sections into unpowered logic - critical for hot-plug and multi-rail system designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables single-supply operation across multiple voltage domains including 1.2 V, 1.8 V, 2.5 V, and 3.3 V systems |
| tpd Max | 5.4 ns at 3.3 V, CL = 5 pF - ensures timing-critical point-to-point buffering with minimal latency |
| ICC Max | 0.9 mA at 3.6 V - guarantees ultra-low static power for extended battery life in portable devices |
| CI Typ | 1.5 pF - reduces capacitive loading on driving sources, preserving signal integrity in high-speed traces |
| Ioff Max | 0.6 mA at 3.6 V - prevents damaging back-current during partial power-down, supporting robust system-level power sequencing |
| IOH/IOL | ±4 mA at 3.0 V - provides sufficient drive strength for fanout of 2–4 standard CMOS loads without external buffers |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial-grade reliability requirements for handling and board assembly |
Pinout & Package
SN74AUP2G125YFPR uses the YFP package: an 8-ball NanoStar™ DSBGA (Die Size Ball Grid Array) with 0.23-mm Pb-free solder bumps, 1.59 mm × 1.53 mm body size, and 0.5 mm max height. Pin 1 is located at the A1 corner (top-left), with ball layout matching the YFP top-view diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | 1OE | Active-low enable for Channel 1 - drives 1Y high-impedance when logic high |
| 2 (A2) | 1A | Input for Channel 1 buffer - accepts 0.8–3.6 V logic levels with hysteresis |
| 3 (B1) | GND | Ground reference - must be connected; exposed center pad may be left open or tied to GND |
| 4 (B2) | 2Y | Output for Channel 2 - 3-state, 3.6-V tolerant, supports Ioff |
| 5 (C1) | VCC | Supply rail - decoupling capacitor required within 1 cm for stable operation |
| 6 (C2) | 2OE | Active-low enable for Channel 2 - independent control enables asymmetric channel gating |
| 7 (D1) | 1Y | Output for Channel 1 - noninverting, 3-state, compatible with mixed-voltage signaling |
| 8 (D2) | 2A | Input for Channel 2 - electrically identical to 1A, supports floating-input disable mode |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 mA max at 3.6 V - extends runtime in coin-cell or energy-harvesting systems |
| Wide VCC compatibility | Operates from 0.8 V to 3.6 V - eliminates need for separate voltage regulators in multi-rail SoC interfaces |
| 3.6-V I/O tolerance | Inputs/outputs withstand up to 3.6 V regardless of VCC - enables direct connection to higher-voltage peripherals |
| Input-disable capability | Floating inputs do not cause leakage or undefined states - simplifies PCB routing and reduces pull-up/pull-down count |
| Ioff partial-power-down | Outputs disabled and isolated when VCC = 0 V - prevents backflow current in hot-swap or sleep-mode applications |
Applications
| Mobile Sensor Hub Interface | Wearable Biometric Data Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G125DCUR | Higher ICC (max 10 µA vs. 0.9 mA), faster tpd (3.8 ns), but no Ioff or input-disable features | Suitable only for always-powered systems; cannot safely isolate unpowered sections | Select when speed > power savings and full-system power cycling is guaranteed |
| 74AHC1G125SE-7 | Single-channel, SOT-353 package, 2–5.5 V VCC, no Ioff, higher drive (±8 mA) | Requires two units for dual-channel function; lacks partial-power-down safety | Choose for space-constrained single-line isolation where cost-per-channel is prioritized over system-level safety |
Compared with SN74LVC2G125DCUR and 74AHC1G125SE-7, SN74AUP2G125YFPR uniquely combines ultra-low ICC, Ioff-enabled power sequencing, and input-disable - making it the only option qualified for battery-operated, multi-rail, and hot-pluggable embedded systems requiring guaranteed isolation during rail transitions.

FAQ
What is the maximum operating temperature range for SN74AUP2G125YFPR?
The SN74AUP2G125YFPR is rated for continuous operation from –40°C to +85°C ambient temperature, validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life standards. This range supports deployment in consumer wearables, industrial handhelds, and automotive cabin electronics where thermal margins are constrained.
Does SN74AUP2G125YFPR support true 1.2-V logic operation?
Yes, SN74AUP2G125YFPR fully supports 1.2-V VCC operation with guaranteed parameters: VIH ≤ 0.65 × VCC (≤0.78 V), VIL ≥ 0.35 × VCC (≥0.42 V), tpd ≤ 19.5 ns (CL = 5 pF), and ICC ≤ 0.5 µA - enabling direct integration with 1.2-V core logic in modern ultra-low-power MCUs without level translation.
Can SN74AUP2G125YFPR be used with 5-V-tolerant microcontrollers?
No - SN74AUP2G125YFPR inputs are rated for absolute maximum VI = –0.5 V to 4.6 V, but functional operation is specified only up to 3.6 V. While 3.6-V I/O tolerance allows interfacing with 3.3-V peripherals, direct connection to 5-V logic violates recommended operating conditions and risks parametric failure or accelerated wear-out.
How is the exposed center pad on SN74AUP2G125YFPR handled in PCB layout?
The exposed center pad on SN74AUP2G125YFPR (YFP package) must be connected only as a secondary GND or left electrically open - it is not internally connected to any signal or power net. TI's recommended land pattern uses a non-solder-mask-defined (NSMD) copper pad with 0.23-mm openings, and thermal vias are optional since power dissipation is <5 mW under typical operation.
Is SN74AUP2G125YFPR pin-compatible with other AUP-family dual buffers?
Yes - SN74AUP2G125YFPR shares identical pinout and functionality with SN74AUP2G125DCUR (VSSOP), SN74AUP2G125DQER (X2SON), and SN74AUP2G125RSER (UQFN) variants. All use the same 8-pin dual-channel 3-state buffer topology with matching A1–D2 ball/pad mapping, enabling drop-in replacement across package types without layout changes.
