Product details
Overview
SN74AUP1G125 from Texas Instruments is a single low-power bus buffer gate with 3-state output, designed for signal isolation and level translation in portable electronics. It operates across 0.8 V to 3.6 V, delivers ≤4.6 ns propagation delay at 3.3 V, supports Ioff partial-power-down mode, and features 3.6-V I/O tolerance for mixed-voltage interfacing - used in SSDs, tablets, and wireless peripherals.
For engineers reviewing the SN74AUP1G125 datasheet, SN74AUP1G125 pinout, SN74AUP1G125 application, or SN74AUP1G125 equivalent, key selection criteria include its ultra-low ICC (0.9 µA max), 1.5 pF input capacitance, 3-state enable timing (tdis/ten ≤5.9 ns at 3.3 V), and DSBGA-5 YZPR package compatibility with high-density PCB layouts.
Technical Context
The SN74AUP1G125 implements a noninverting buffer with active-low output-enable (OE) control, enabling precise bus contention management. Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining rail-to-rail VOH/VOL compliance across the full 0.8–3.6 V supply range.
It integrates Ioff circuitry that disables inputs/outputs during power-down, limiting leakage to ≤0.6 µA at –40°C to +85°C, and includes input hysteresis for noise immunity on slow transitions - critical for reliable operation in battery-powered audio docks and wireless headsets.
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 logic domains without level shifters |
| tpd (max) | 4.6 ns at 3.3 V - supports signal integrity up to ~100 MHz in point-to-point routing |
| ICC (max) | 0.9 µA at TA = –40°C to +85°C - extends battery life in always-on portable subsystems |
| Ioff (max) | 0.6 µA at VCC = 0 V - prevents backflow current during partial power-down in multi-rail systems |
| CI (typ) | 1.5 pF - minimizes capacitive loading on driving sources, preserving rise/fall times |
| IOH/IOL | ±4 mA at 3 V - sufficient to drive multiple CMOS inputs or low-current LEDs directly |
| VIO Tolerance | 3.6 V - allows 5-V-tolerant inputs when VCC = 1.8 V or 2.5 V, simplifying voltage translation |
Pinout & Package
SN74AUP1G125YZPR uses a 5-pin DSBGA (Die Size Ball Grid Array) package measuring 0.89 mm × 1.39 mm, bottom-terminal configuration optimized for space-constrained mobile PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives output Y to high-impedance state when high; must be pulled up to VCC during power sequencing |
| 2 (A) | Noninverting data input | Accepts 0.8–3.6 V logic; supports floating input via internal disable feature |
| 3 (GND) | Ground reference | Primary return path for I/O and supply currents; requires low-inductance connection |
| 4 (Y) | 3-state buffered output | Delivers A when OE = L; high-Z when OE = H; rated for ±20 mA continuous drive |
| 5 (VCC) | Positive supply | Supplies core logic and output drivers; bypass capacitor required per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Input-disable capability | Allows A to float without causing undefined logic states or increased ICC, simplifying unconnected signal handling |
| Ioff partial-power-down | Prevents current backflow into powered-down sections, enabling safe hot-insertion in modular systems |
| Low input capacitance (1.5 pF) | Reduces loading on preceding drivers, preserving signal edge rates in high-speed interconnects |
| Wide VCC range (0.8–3.6 V) | Eliminates need for external regulators in multi-supply SoC interfaces, e.g., between AP and PMIC rails |
| Overshoot/undershoot <10% of VCC | Minimizes EMI and crosstalk in dense layouts, meeting Class B emission requirements without added filtering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125YZPR | Higher ICC (10 µA typ), narrower VCC range (1.65–5.5 V), no Ioff support | Lacks partial-power-down capability; unsuitable for battery-backed or hot-swap systems | Choose only if higher drive strength (±32 mA) and 5-V compatibility outweigh ultra-low-power needs |
| 74AHC1G125GW,125 | Wider VCC (2–5.5 V), higher tpd (7.5 ns min), no input-disable or Ioff | Not usable below 2 V; incompatible with sub-1.8 V SoC I/O standards | Select when interfacing legacy 3.3/5-V logic and thermal budget permits higher dynamic power |
Compared with SN74LVC1G125YZPR and 74AHC1G125GW,125, the SN74AUP1G125YZPR uniquely combines sub-1-V operation, Ioff, and <1 µA static current - making it the sole option for energy-critical wearable and IoT endpoints where supply voltage scaling and zero-power isolation are mandatory.

FAQ
What is the maximum operating temperature range for the SN74AUP1G125YZPR?
The SN74AUP1G125YZPR is specified for operation from –40°C to +85°C ambient temperature. This range is validated across all electrical parameters including ICC, Ioff, VOH/VOL, and tpd, ensuring reliability in consumer handhelds and industrial edge devices where thermal cycling occurs.
Does the SN74AUP1G125YZPR support true 5-V input tolerance?
No - the SN74AUP1G125YZPR supports 3.6-V absolute maximum input voltage, not 5 V. However, its inputs are over-voltage tolerant up to 3.6 V regardless of VCC, enabling safe interfacing with 3.3-V systems even when VCC = 1.8 V. For 5-V tolerant operation, consider SN74LVC1G125YZPR instead.
How should the OE pin be handled during power-up to ensure high-impedance state?
To guarantee high-impedance output during power-up or power-down, the OE pin of the SN74AUP1G125YZPR must be tied to VCC through an external pullup resistor. The minimum resistance value depends on the driver's sink capability - TI recommends ≥10 kΩ for typical use, verified in the device's functional modes table.
Can the SN74AUP1G125YZPR drive an LED directly?
Yes - the SN74AUP1G125YZPR can source/sink up to ±4 mA at 3 V, sufficient for low-current indicator LEDs (e.g., 2 mA @ 2 V forward drop). For higher-brightness LEDs requiring >5 mA, add an external transistor stage; the device's 3-state output also enables multiplexed LED control without additional logic.
Is the SN74AUP1G125YZPR pin-compatible with other AUP family variants in DSBGA-5?
Yes - SN74AUP1G125YZPR shares identical pinout (OE-A-GND-Y-VCC) and footprint with other YZP/YZT-packaged AUP single-gate devices like SN74AUP1G00YZPR and SN74AUP1G08YZPR, enabling drop-in logic substitution in existing layouts without PCB revision.
