Product details
Overview
74AUP1G125FX4-7 from Diodes Incorporated is a single non-inverting buffer gate with 3-state output, designed for ultra-low-power portable systems operating from 0.8V to 3.6V. It delivers ±4mA drive at 3.0V, features IOFF partial power-down protection, and uses Schmitt-trigger inputs (250mV hysteresis at 3.0V) for robust noise immunity in battery-powered interfaces.
For engineers reviewing the 74AUP1G125FX4-7 datasheet, 74AUP1G125FX4-7 pinout, 74AUP1G125FX4-7 application, or 74AUP1G125FX4-7 equivalent, this device supports low-voltage bus buffering, I/O expansion, and power-gated subsystem isolation where static current <0.9µA and dynamic CPD = 6.3pF are critical selection criteria.
Technical Context
The 74AUP1G125FX4-7 implements a CMOS-based non-inverting buffer with active-low 3-state enable (OE), entering high-impedance output when OE = HIGH. Its IOFF circuit actively disables both output and input paths during VCC = 0V, preventing backflow current in partial-power-down systems.
Schmitt-trigger inputs provide 250mV typical hysteresis at VCC = 3.0V, enabling reliable operation with slow-rising signals common in low-power sensor or control interfaces. Propagation delay is 2.4ns (typ) at 3.3V/CL = 5pF, and enable/disable times are 2.4ns/3.9ns (typ) under same conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - enables direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters |
| Output Drive | ±4mA at 3.0V - sufficient to drive 50Ω transmission lines or multiple standard CMOS loads in compact layouts |
| Static Current (ICC) | <0.9µA - extends battery life in always-on monitoring circuits and sleep-mode subsystems |
| Dynamic Power (CPD) | 6.3pF at 3.6V - minimizes switching losses in high-frequency data paths up to ~100MHz |
| IOFF Leakage | ±0.2µA max at 3.6V - ensures safe hot-insertion and multi-rail power sequencing without latch-up risk |
| Input Hysteresis | 250mV typ at 3.0V - rejects noise on slow GPIO or analog-sensor digital outputs without external RC filtering |
| Propagation Delay | 2.4ns typ at 3.3V/5pF - supports timing-critical signal routing in portable SoC interconnects |
Pinout & Package
X2-DFN1409-6 package: 1.4mm × 0.9mm × 0.4mm, 0.5mm pad pitch, leadless, bottom-side thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Non-inverting input with Schmitt-trigger threshold; accepts 0.8–3.6V logic levels regardless of VCC |
| 2 (OE) | Output Enable (Active Low) | Drives output to high-impedance when HIGH; IOFF active during VCC = 0V to block backfeed |
| 3 (GND) | Ground Reference | Return path for all internal logic and output current; must be low-inductance connection for EMI control |
| 4 (Y) | 3-State Output | Buffered non-inverted signal; high-Z state leakage ≤±0.2µA supports multi-drop bus arbitration |
| 5 (VCC) | Power Supply | Supplies core logic and output drivers; decoupling capacitor (100nF) required within 2mm of pin |
| 6 (NC) | No Connect | Internally unconnected die pad; must remain floating or tied to GND per layout guidelines to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Ultra Low Power (AUP) CMOS | Enables sub-1µA standby current in always-on wearables and IoT edge nodes without sacrificing speed |
| IOFF Partial Power-Down Support | Prevents damaging current flow between powered/unpowered rails during system sleep or hot-swap events |
| Schmitt-Trigger Inputs | Eliminates need for external hysteresis components in noisy environments like motor-control feedback or battery-sense lines |
| ESD Robustness | 2000V HBM / 1000V CDM rating allows direct PCB handling and integration into consumer-grade assemblies without extra protection |
| Lead-Free & Halogen-Free | Fully RoHS 2 and "Green" compliant (Br+Cl <1500ppm, Sb <1000ppm), suitable for global eco-regulated products |
Applications
| Mobile Device Power Management | Low-Voltage Sensor Interface |
|---|---|
|
Use Scenario: Isolating battery-monitoring ADC inputs from main SoC domain during deep-sleep mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Wider VCC range (1.65–5.5V); higher ICC (10µA typ); no IOFF; 5-pin SOT-23 package | Requires level-shifting for sub-1.65V systems; unsuitable for true partial-power-down scenarios | Select when interfacing legacy 5V peripherals or where higher drive strength (±24mA) outweighs ultra-low ICC. |
| 74LVC1G125GW,125 | Same AUP family but in SOT323 (2.1×2.3mm); identical electrical specs except θJA = 371°C/W vs. 470°C/W | Larger footprint; better thermal performance; less suitable for ultra-dense mobile PCBs | Select when thermal margin >0.5W dissipation is required or existing SOT323 land pattern is fixed. |
Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the 74AUP1G125FX4-7 uniquely combines sub-1µA ICC, IOFF, and 1.4×0.9mm DFN packaging-making it the only choice for space-constrained, multi-rail battery systems requiring guaranteed zero-backfeed behavior.

FAQ
What is the maximum recommended operating temperature for 74AUP1G125FX4-7?
The device is rated for continuous operation from –40°C to +125°C ambient temperature. Junction temperature must not exceed +150°C; with θJA = 470°C/W in X2-DFN1409-6, power dissipation should be limited to ≤127mW at TA = 125°C to maintain TJ ≤ 150°C.
Can 74AUP1G125FX4-7 drive a 50Ω transmission line directly?
Yes-its ±4mA output drive at 3.0V provides sufficient current to terminate and drive a 50Ω line with <1V swing (VOL ≈ 0.31V, VOH ≈ 2.67V). For clean 3.3V signaling, use series termination at source or parallel termination at load to match impedance and suppress reflections.
Is the NC pin (Pin 6) required to be grounded?
No-Pin 6 is a no-connect die pad with no internal connection. Diodes Incorporated's AP02002 layout guide specifies it may be left floating or connected to GND for mechanical stability; grounding improves thermal conduction but is not electrically necessary.
Does the Schmitt-trigger input affect propagation delay?
Yes-the hysteresis adds minimal delay (<0.3ns) versus a standard CMOS input, but enables reliable switching with input rise/fall times up to 200ns/V. At 3.3V, typical tPD remains 2.4ns (CL = 5pF), unchanged from non-Schmitt variants in the same family.
