Product details
Overview
74AUP1G38GX,125 from Nexperia is a single 2-input NAND gate with open-drain output, Schmitt-trigger inputs, and IOFF partial power-down capability. It operates across 0.8 V to 3.6 V supply, delivers ≤1.4 μA max ICC at −40 °C to +125 °C, supports ≤0.50 V VOL at 4 mA load (VCC = 3.0 V), and features 5-terminal X2SON5 (SOT1226-3) packaging. It is used in level-shifting I²C bus interfaces and low-power sensor wake-up logic.
For engineers reviewing the 74AUP1G38GX,125 datasheet, 74AUP1G38GX,125 pinout, 74AUP1G38GX,125 application, or 74AUP1G38GX,125 equivalent, this device serves as a low-voltage, low-noise combinational logic element where rail-to-rail input tolerance, ultra-low static current, and guaranteed open-drain switching behavior are critical selection criteria.
Technical Context
The 74AUP1G38GX,125 implements a single 2-input NAND function with true open-drain output - no internal pull-up - requiring external termination. Its Schmitt-trigger inputs provide hysteresis (typ. 0.1 × VCC) to reject slow-rising noise on battery-backed or long-trace signals.
IOFF circuitry actively disables output leakage when VCC = 0 V, limiting backflow current to ±0.75 μA across −40 °C to +125 °C. Input voltage tolerance extends to 3.6 V regardless of VCC, enabling mixed-voltage domain interfacing without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage 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 |
| Max ICC (−40 °C to +125 °C) | 1.4 μA - ensures <1 μW static power at 1.8 V, critical for always-on sensor nodes |
| VOL @ 4 mA, VCC = 3.0 V | ≤0.50 V - guarantees robust LOW-state margin for 3.3 V-tolerant open-drain buses |
| tpd @ CL = 15 pF, VCC = 1.8 V | ≤6.5 ns - supports >30 MHz toggle rates in compact timing-critical paths |
| Input Hysteresis | Typ. 0.1 × VCC - rejects up to 180 mV of low-frequency noise on slow GPIO lines |
| ESD Robustness | HBM >5000 V, CDM >1000 V - withstands handling and board-level ESD events without protection diodes |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial edge controllers |
Pinout & Package
X2SON5 package (SOT1226-3): plastic thermal-enhanced extremely thin small outline, 5 terminals, body size 0.8 mm × 0.8 mm × 0.32 mm, no leads, exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | First logic input; Schmitt-triggered, overvoltage tolerant to 3.6 V independent of VCC |
| 2 | B | Second logic input; identical electrical characteristics to Pin 1 |
| 3 | GND | Digital ground reference; must be low-impedance connection to minimize ground bounce |
| 4 | Y | Open-drain output; requires external pull-up; sinks up to 20 mA; no internal pull-up |
| 5 | VCC | Supply voltage input; powers internal logic and IOFF control; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (0.8 V–3.6 V) | Supports direct integration into multi-rail systems without voltage translators |
| IOFF partial power-down | Prevents damaging back-current flow when VCC = 0 V, enabling hot-swap and sleep-mode isolation |
| Schmitt-trigger inputs | Eliminates need for external RC filtering on noisy or slow-switching sensor/switch inputs |
| Overvoltage-tolerant inputs | Accepts 3.6 V signals even at VCC = 0.8 V - enables safe interfacing with higher-voltage peripherals |
| Low dynamic power (CPD = 0.9 pF typ.) | Reduces switching energy by >60% vs. standard AUP series at 1.8 V, 10 MHz operation |
Applications
| Industrial Sensor Interface | I²C Bus Level Shifting |
|---|---|
|
Use Scenario: A 1.8 V microcontroller reads a 3.3 V digital temperature sensor via GPIO polling. IC Role / Device Role / Timing Role: Acts as bidirectional level translator using open-drain wired-AND topology with external pull-ups on both sides. Use Value: Eliminates need for dedicated level-shifter IC; Schmitt inputs suppress noise from long sensor traces. |
Use Scenario: Two I²C masters operating at different supply voltages share one bus segment. IC Role / Device Role / Timing Role: Provides voltage-domain isolation between 1.8 V and 3.3 V I²C sections using dual open-drain gates. Use Value: Enables interoperability without bus contention; IOFF prevents leakage during master power cycling. |
| Low-Power Wake-Up Logic | Reset Signal Conditioning |
|
Use Scenario: A motion sensor asserts an active-low interrupt to wake a sleeping MCU only when both PIR and ambient light conditions are met. IC Role / Device Role / Timing Role: Implements NAND-based AND logic with hysteresis to debounce mechanical switch or analog comparator outputs. Use Value: Reduces system standby current to sub-μA levels; eliminates external RC debouncing components. |
Use Scenario: Power-on reset signal must be held LOW until VCC stabilizes and a watchdog timer expires. IC Role / Device Role / Timing Role: Combines delayed reset signal and watchdog timeout using NAND gate with open-drain output tied to system RESET line. Use Value: Ensures deterministic reset assertion timing; IOFF prevents unintended reset release during brown-out recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G38GW,125 | Higher ICC (max 4 μA), no Schmitt inputs, narrower VCC range (1.65 V–5.5 V) | Not suitable for sub-1.65 V operation or noisy input environments | Select only if VCC ≥ 1.65 V and input edges are clean; lower cost but reduced noise immunity |
| SN74LVC1G00DBVR | Pull-up required for push-pull output; no IOFF; max VCC = 5.5 V; no overvoltage tolerance | Cannot replace in hot-swap or mixed-voltage systems without redesign | Choose only for fixed 3.3 V systems with fast, clean signals and no power sequencing constraints |
Compared with 74LVC1G38GW,125 and SN74LVC1G00DBVR, the 74AUP1G38GX,125 uniquely combines ultra-low ICC, Schmitt inputs, IOFF, and 0.8 V operation - making it the sole option for battery-powered, noise-prone, or multi-rail designs requiring guaranteed open-drain behavior.

FAQ
Can 74AUP1G38GX,125 drive a 10 kΩ pull-up to 5 V?
No. The output is rated for VO ≤ 3.6 V maximum under any condition. Driving a 5 V pull-up violates absolute maximum ratings and risks permanent damage. Use only pull-ups to VCC or ≤3.6 V supplies, with current limited by external resistor to ≤20 mA.
Does the IOFF feature activate automatically when VCC drops below threshold?
Yes. IOFF engages when VCC falls below ~0.2 V - no enable pin or control signal required. Output transitions to high-impedance state within nanoseconds, blocking reverse current from Y or inputs into the powered-down device.
Is the X2SON5 package (SOT1226-3) compatible with standard reflow profiles?
Yes. SOT1226-3 is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its 0.32 mm height and thermal pad design ensure reliable solder joint formation under standard lead-free profiles.
What is the minimum recommended VCC for guaranteed VIH/VIL thresholds?
0.8 V is the absolute minimum per datasheet. At VCC = 0.8 V, VIH = 0.70 × VCC = 0.56 V (min), and VIL = 0.30 × VCC = 0.24 V (max). These thresholds remain valid across −40 °C to +125 °C, ensuring robust logic discrimination at lowest supply.
