Product details
Overview
74AUP1G125FW4-7 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 74AUP1G125FW4-7 datasheet, 74AUP1G125FW4-7 pinout, 74AUP1G125FW4-7 application, or 74AUP1G125FW4-7 equivalent, this device serves as a low-voltage bus driver in space-constrained, power-sensitive signal routing-especially where dynamic supply scaling, high-impedance isolation, and ESD-hardened I/O are required.
Technical Context
This AUP-family CMOS buffer implements a single-channel non-inverting logic path with active-low output enable (OE), enabling precise control of bidirectional data flow on shared buses. Its IOFF circuit actively disables outputs during power-down, preventing back-current into powered-down sections of mixed-supply systems.
Schmitt-trigger inputs tolerate slow-rising signals (≤200 ns/V transition rate) and provide stable switching across voltage rails from 0.8V to 3.6V. The device supports full rail-to-rail input and output swing, with guaranteed VIH/VIL thresholds defined per VCC range (e.g., VIH = 0.80×VCC at 0.8–1.65V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - enables direct interface with sub-1V logic, 1.2V/1.8V/2.5V/3.3V domains without level shifters. |
| Output Drive Strength | ±4mA at 3.0V - sufficient to drive 50Ω transmission lines or multiple CMOS loads in compact PCB layouts. |
| Static Supply Current | <0.9µA max - extends battery life in always-on sensor nodes and standby-mode peripherals. |
| IOFF Leakage | ±0.5µA max at 3.6V - ensures safe isolation when VCC = 0V while other system rails remain active. |
| Propagation Delay | 1.2ns typical at 3.3V, CL = 5pF - supports >100MHz data rates in short-reach digital interconnects. |
| Input Hysteresis | 250mV typical at VCC = 3.0V - rejects noise up to ±125mV on slow-switching control lines (e.g., pushbutton debouncing). |
| ESD Rating | 2000V HBM, 1000V CDM - meets industrial handling requirements without external protection components. |
Pinout & Package
X2-DFN1010-6 package: 1.0mm × 1.0mm × 0.4mm body, 0.35mm pad pitch, no leads, bottom thermal pad, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Non-inverting logic input; accepts 0.8V–3.6V CMOS levels; Schmitt-triggered for noise margin. |
| 2 (OE) | Active-Low Output Enable | Drives output Y to high-impedance state when HIGH; must be pulled LOW to enable buffer function. |
| 3 (GND) | Ground Reference | Primary return path for all internal logic and I/O; requires low-inductance connection to PCB ground plane. |
| 4 (Y) | 3-State Output | Buffered, non-inverted copy of A when OE = LOW; high-Z when OE = HIGH; drives up to ±4mA. |
| 5 (VCC) | Power Supply | Single supply rail (0.8–3.6V); decoupling capacitor (≥100nF) required within 2mm of pin. |
| 6 (NC) | No Connect | Internally unconnected; must be left floating or tied to GND per layout best practice for thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Ultra Low Power (AUP) CMOS | ICC < 0.9µA at 3.6V - reduces quiescent load on coin-cell or energy-harvesting supplies. |
| IOFF Partial Power-Down Support | Blocks reverse current flow when VCC = 0V - enables hot-swap and multi-rail sequencing in modular systems. |
| Schmitt-Trigger Inputs | 250mV hysteresis at 3.0V - eliminates contact bounce artifacts and allows use with RC-filtered or long-trace signals. |
| Lead-Free & Halogen-Free Construction | JESD30E-compliant X2-DFN1010-6 package - satisfies IPC/JEDEC J-STD-020 moisture sensitivity Level 1 and RoHS 2 compliance. |
| Low Dynamic Power Consumption | CPD = 6.3pF typical at 3.6V - minimizes switching losses in high-frequency clock distribution or data strobing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nexperia 74AUP1G125FW4-7 | Identical pinout, package, and electrical specs; same AUP family architecture and IOFF behavior. | No functional difference; qualified for identical automotive AEC-Q100 Grade 2 temperature range (-40°C to +105°C). | Select for dual-sourcing assurance in automotive infotainment or ADAS modules requiring extended qualification. |
| Texas Instruments SN74LVC1G125DBVR | Higher ICC (10µA typ), narrower VCC range (1.65–5.5V), no IOFF, no Schmitt inputs. | Lacks partial power-down capability and noise-immune input; requires external pull-ups for open-drain emulation. | Choose only if operating exclusively above 1.65V and system design already accommodates higher static current and no IOFF requirement. |
Compared with Nexperia's 74AUP1G125FW4-7, Diodes' version offers identical performance but with broader industrial temperature support (−40°C to +125°C vs. −40°C to +105°C); versus TI's SN74LVC1G125DBVR, it adds critical IOFF and Schmitt functionality essential for battery-powered and noisy environments.

FAQ
What is the maximum recommended operating temperature for the 74AUP1G125FW4-7?
The device is fully specified over −40°C to +125°C ambient temperature. Thermal resistance θJA is 445°C/W for the X2-DFN1010-6 package, so junction temperature remains within safe limits (<150°C) with ≤1.5mW power dissipation under typical conditions. Derating is not required below +125°C ambient.
Can the 74AUP1G125FW4-7 drive a 50Ω transmission line directly?
Yes - at 3.0V supply, it delivers ±4mA output drive, sufficient to source/sink 60mA into a 50Ω load at 3V swing (VOL ≈ 0.44V, VOH ≈ 2.6V). For clean 100MHz+ signaling, use controlled-impedance routing and place a 22Ω series resistor near the driver output to dampen reflections.
Is the NC pin (Pin 6) required to be grounded?
No - Pin 6 is internally unconnected and must remain floating. Diodes Incorporated's AP02002 pad layout recommends leaving it unconnected or optionally connecting to GND only for mechanical stability or thermal relief; grounding does not affect electrical performance but may improve solder joint reliability in reflow processes.
Does the 74AUP1G125FW4-7 support hot insertion into a live backplane?
Yes - its IOFF circuitry ensures outputs enter high-impedance state and limit leakage to ±0.5µA when VCC = 0V, even with valid input voltages present. This prevents bus contention and back-driving during hot-plug events, satisfying IEC 61000-4-2 Level 4 ESD immunity requirements without external protection.
