Product details
Overview
74AUP1G126FX4-7 from Diodes Incorporated is a single non-inverting 3-state buffer IC designed for ultra-low-power portable logic interfacing. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and uses Schmitt-trigger inputs with ~250mV hysteresis at 3.0V. It serves in voltage-level translation and bus isolation within battery-powered mobile peripherals.
For engineers reviewing the 74AUP1G126FX4-7 datasheet, 74AUP1G126FX4-7 pinout, 74AUP1G126FX4-7 application, or 74AUP1G126FX4-7 equivalent, this device is selected for its sub-1µA static ICC, 0.5mm-pitch X2-DFN1409-6 package, IOFF-enabled system power sequencing, and guaranteed 3.1ns propagation delay at 3.3V/5pF load.
Technical Context
This CMOS buffer implements a single-channel, non-inverting data path with active-high Output Enable (OE), entering high-impedance state when OE = LOW. Its IOFF circuit disables both input and output paths during VCC power-down, preventing backflow current into powered rails.
The Schmitt-trigger input provides noise immunity with 250mV typical hysteresis at VCC = 3.0V, enabling reliable operation with slow-rising signals. All electrical characteristics-including VIH/VIL thresholds, VOL/VOH levels, and tpd/ten/tDIS timing-are fully specified across −40°C to +125°C and 0.8V–3.6V VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - supports direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic domains |
| Output Drive Strength | ±4mA at VCC = 3.0V - sufficient to drive 50Ω transmission lines or multiple 74AUP inputs |
| Static Supply Current | <0.9µA max at +25°C - enables multi-year battery life in always-on sensor nodes |
| Propagation Delay | 1.4ns typical (tpd, A→Y) at VCC = 3.3V, CL = 5pF - meets timing budgets for low-latency control signaling |
| IOFF Leakage | ±0.5µA max at VCC = 0V - prevents >1µA backfeed current during partial power-down sequences |
| Input Hysteresis | 250mV typical at VCC = 3.0V - rejects up to ±125mV of common-mode noise on slow GPIOs |
| ESD Rating | 2kV HBM, 1kV CDM - exceeds IEC 61000-4-2 Level 2 for handheld product robustness |
Pinout & Package
X2-DFN1409-6 package: 1.4mm × 0.9mm × 0.4mm body, 0.5mm pad pitch, 6-terminal leadless chip-scale design with exposed thermal pad (non-electrical). RoHS-compliant, halogen-free, green-qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Non-inverting logic input; accepts 0.8V–3.6V CMOS-compatible signals with Schmitt-trigger threshold |
| 2 (OE) | Output Enable | Active-HIGH control: HIGH enables buffer output; LOW forces Y into high-impedance state |
| 3 (GND) | Ground Reference | Primary return path for VCC current and signal reference; must be low-inductance connection |
| 4 (Y) | 3-State Output | Buffered non-inverted output; high-Z when OE = LOW; drives up to ±4mA at 3.0V |
| 5 (VCC) | Power Supply | Core logic supply; supports 0.8V–3.6V operation; decoupling capacitor required near pin |
| 6 (NC) | No Connect | Internally unconnected terminal; must be left floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA ensures negligible quiescent drain in sleep-mode IoT endpoints |
| IOFF partial power-down | Blocks current flow between powered/unpowered sections during hot-swap or rail sequencing |
| Schmitt-trigger inputs | 250mV hysteresis eliminates contact bounce or EMI-induced glitches on mechanical switches |
| Wide VCC range | Single part replaces multiple voltage-specific buffers (e.g., 1.2V/1.8V/2.5V/3.3V families) |
| Small-footprint DFN | X2-DFN1409-6 (1.4×0.9mm) saves >60% board area vs. SOT353 while improving thermal resistance |
Applications
| Mobile Display Interface | Wearable Sensor Hub |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance (1.5pF Ci), low-delay buffer maintains signal integrity across isolation barrier. Use Value: 6.3pF typical Cpd minimizes loading on isolated SPI bus; 0.8V–3.6V range matches diverse isolated rail voltages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G126DBVR | Higher ICC (10µA typ), no IOFF, 1.65V–5.5V VCC range | Not suitable for partial power-down systems; requires ≥1.65V supply | Select only if operating above 1.65V and IOFF is unnecessary |
| 74LVC1G125GW,125 | Inverting function (A→Y̅), same VCC range and IOFF support | Requires logic inversion in signal path; identical footprint but different truth table | Choose only when system-level inversion is acceptable or required |
Compared with SN74LVC1G126DBVR and 74LVC1G125GW,125, the 74AUP1G126FX4-7 uniquely combines sub-1µA ICC, 0.8V minimum VCC, and IOFF-making it the sole option for ultra-low-power, multi-rail, hot-pluggable designs where leakage and voltage flexibility are critical.

FAQ
What is the maximum recommended operating temperature for 74AUP1G126FX4-7?
The device is fully specified from −40°C to +125°C ambient temperature. Junction temperature must not exceed +150°C under steady-state conditions. Thermal resistance θJA for the X2-DFN1409-6 package is 470°C/W on standard FR-4 PCB, so derating is required above 85°C ambient at full load.
Can 74AUP1G126FX4-7 drive a 50Ω transmission line directly?
Yes-its ±4mA output drive at 3.0V supports 50Ω termination (VOL ≈ 0.31V at IOL = 4mA, VOH ≈ 2.67V at IOH = −4mA). For clean 3.3V signaling, use series source termination or ensure trace impedance matches output impedance under load.
Is the NC pin (Pin 6) required to be grounded?
No-Pin 6 is internally unconnected and must remain floating. Diodes Incorporated's AP02002 layout guide specifies no solder mask defined for this pad; grounding it may cause unintended parasitic coupling or violate thermal pad clearance rules.
Does the Schmitt-trigger input affect propagation delay?
No-the 1.4ns typical tpd (A→Y) at 3.3V/5pF includes Schmitt-trigger internal delay. The hysteresis adds no measurable timing penalty versus standard CMOS input; it only modifies input threshold behavior to improve noise margin without impacting output edge rate or latency.
