Product details
Overview
74AUP1G126FW5-7 from Diodes Incorporated is a single non-inverting 3-state buffer gate in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for battery-powered portable systems. 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 for noise immunity in low-speed signal routing.
For engineers reviewing the 74AUP1G126FW5-7 datasheet, 74AUP1G126FW5-7 pinout, 74AUP1G126FW5-7 application, or 74AUP1G126FW5-7 equivalent, this device serves as a voltage-scalable, ultra-low-quiescent-current bus driver for I/O isolation, level translation, and power-gated subsystem control in space-constrained mobile and embedded designs.
Technical Context
This device implements a single-channel non-inverting buffer with active-high 3-state output enable (OE), enabling bidirectional bus control and signal isolation in mixed-voltage domains. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, satisfying partial-power-down requirements per JESD78 Class I latch-up immunity.
The input stage integrates Schmitt-trigger action-verified at 250mV typical hysteresis at VCC = 3.0V-ensuring robust operation with slow-rising or noisy signals. Propagation delay is load- and voltage-dependent: tPD = 1.4ns (typ) at 3.3V/CL = 5pF, rising to 2.0ns at CL = 30pF, while enable/disable times (tEN/tDIS) remain under 4.7ns (typ) at same conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - supports direct interfacing with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters. |
| Output Drive Strength | ±4mA at VCC = 3.0V - sufficient to drive standard CMOS loads and short PCB traces in portable applications. |
| Static Supply Current | ICC < 0.9µA (max) - enables multi-year battery life in always-on sensor nodes or standby subsystems. |
| IOFF Leakage | ±0.5µA max (VI/VO = 0V to 3.6V) - prevents damaging back-current when VCC is off but I/O lines remain live. |
| Input Hysteresis | ~250mV at VCC = 3.0V - rejects noise on slow-switching control lines such as reset, enable, or configuration pins. |
| Propagation Delay | 1.4ns (typ) at 3.3V/5pF - meets timing budgets for high-speed data gating in USB, SDIO, or display interface sub-circuits. |
| ESD Robustness | 2kV HBM, 1kV CDM - exceeds industrial IEC 61000-4-2 system-level ESD requirements for handheld end equipment. |
Pinout & Package
X1-DFN1010-6 package: 1.0mm × 1.0mm × 0.5mm body, 0.35mm pad pitch, 6-terminal leadless DFN with exposed thermal pad (Type B). Pin 1 marked by chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Non-inverting input accepting 0.8V–3.6V logic levels; Schmitt-triggered for noise margin. |
| 2 (OE) | Output Enable (Active-High) | Drives output Y to high-impedance state when LOW; IOFF active during VCC = 0V. |
| 3 (GND) | Ground Reference | Primary return path for all internal logic and output current; must be low-inductance connection. |
| 4 (Y) | 3-State Output | Buffered non-inverted output; sinks or sources up to ±4mA; high-Z when OE = LOW. |
| 5 (VCC) | Power Supply | Core logic and I/O supply; decoupling capacitor (100nF) required within 2mm of pin. |
| 6 (NC) | No Connect | Internally unconnected terminal; must be left floating or tied to GND per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Ultra Low Power (AUP) CMOS | Enables <0.9µA ICC in static mode - critical for energy harvesting and coin-cell-powered IoT endpoints. |
| IOFF Partial Power-Down Support | Prevents reverse current flow when VCC = 0V and I/O lines are biased - eliminates need for external blocking diodes. |
| Schmitt-Trigger Inputs | 250mV typical hysteresis at 3.0V - tolerates slow edges from mechanical switches, sensors, or RC-filtered signals. |
| Lead-Free & Halogen-Free "Green" Construction | Fully RoHS 2 compliant with <900ppm Br+Cl and <1000ppm Sb - satisfies global environmental compliance for consumer electronics. |
| Wide-Voltage Operation (0.8V–3.6V) | Eliminates level translators between 1.2V SoC cores and 3.3V peripherals - reduces BOM count and board area. |

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 74AUP1G126FW4-7 | Same AUP family, X2-DFN1010-6 package (1.0mm × 1.0mm × 0.4mm), identical electrical specs, but different marking code and thermal resistance (θJA = 445°C/W vs. 435°C/W). | Compatible in footprint and function; slightly higher thermal resistance limits continuous 4mA drive at >85°C ambient. | Select when sourcing flexibility is needed and thermal margin >5°C is available in final layout. |
| Toshiba TC7S126FU,LF | Lower drive (±2.6mA at 3.0V), higher ICC (1.5µA max), no IOFF support, same 0.8V–3.6V range, SOT-353 package (2.0mm × 2.0mm). | Larger footprint, no partial power-down capability - unsuitable for battery-backed systems requiring zero-backflow safety. | Choose only for cost-sensitive, non-battery applications where IOFF and ultra-low ICC are not required. |
Compared with 74AUP1G126FW5-7, the Nexperia variant offers identical functionality in a mechanically similar package with marginal thermal trade-offs, while the Toshiba part lacks IOFF and delivers less drive - making the Diodes device the sole choice for safety-critical, ultra-low-power portable designs.

FAQ
What is the maximum recommended operating temperature for 74AUP1G126FW5-7?
The device is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature limited to +150°C. At 3.3V and full 4mA output load, thermal resistance θJA = 435°C/W requires ≤25°C ambient to maintain TJ < 125°C in still air - forced airflow or copper pour improves margin.
Does 74AUP1G126FW5-7 support true bidirectional data flow?
No - it is a unidirectional non-inverting buffer with fixed input (A) and output (Y) terminals. Bidirectional operation requires external control logic or a dedicated transceiver; this device provides only one-way signal gating with 3-state output disable.
Can the NC pin (Pin 6) be grounded or left floating?
Per Diodes' AP02002 layout guide, Pin 6 is internally unconnected and must be left floating. Grounding it may cause parasitic coupling or violate package stress specifications; no electrical benefit or risk mitigation is achieved by connecting it.
How does IOFF behavior differ from standard high-impedance state?
Standard 3-state disables output drivers but leaves input circuitry active, allowing back-current if VCC = 0V and I/O lines are pulled high. IOFF actively disconnects both input and output structures from VCC/GND, limiting leakage to ±0.5µA even when VCC = 0V and pins are biased to 3.6V.
