Product details
Overview
74AUP1G240GX,125 from Nexperia is a single-channel low-power inverting buffer/line driver with 3-state output and Schmitt-trigger inputs, operating from 0.8 V to 3.6 V supply. It features output enable (OE) control, IOFF partial power-down protection, and supports industrial temperature range (−40 °C to +125 °C) in X2SON5 package. Used for signal level translation and bus isolation in ultra-low-power IoT sensor interfaces.
For engineers reviewing the 74AUP1G240GX,125 datasheet, 74AUP1G240GX,125 pinout, 74AUP1G240GX,125 application, or 74AUP1G240GX,125 equivalent, key selection criteria include its 0.9 μA max ICC at 3.6 V, 5-pin X2SON5 thermal-enhanced footprint, Schmitt-trigger noise immunity, and guaranteed IOFF operation during system power sequencing.
Technical Context
This device implements a single inverting logic gate with tristate output controlled by an active-low OE input. Its Schmitt-trigger inputs tolerate slow-rising signals and reject noise up to ±30 % of VCC, enabling robust interfacing with mechanical switches or RC-debounced sources.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA and preventing damage during hot-insertion or partial power-down sequences-critical for battery-backed subsystems and modular embedded designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - Enables direct interface with 0.9 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (VCC = 3.6 V) | 0.9 μA - Ensures sub-1 μA static power draw in always-on sensor nodes or real-time clock backup paths. |
| IOFF Leakage (VCC = 0 V) | ±0.75 μA - Prevents >100 μA destructive back-current during board-level power sequencing or module hot-swap. |
| tpd (VCC = 3.3 V, CL = 5 pF) | 3.6 ns - Supports clean signal buffering at >100 MHz data rates in low-voltage serial control lines. |
| Input Hysteresis | Typ. 0.1 × VCC - Rejects noise spikes up to 330 mV on 3.3 V inputs, eliminating external RC filtering in noisy industrial environments. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive ECUs, industrial motor drives, and outdoor edge computing hardware. |
Pinout & Package
X2SON5 package (SOT1226-3): 0.8 mm × 0.8 mm × 0.32 mm body, 5-terminal no-lead thermal-enhanced outline with exposed die pad for improved heat dissipation in space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable Input | Active-HIGH control: drives Y to high-impedance when HIGH; enables inversion when LOW. |
| 2 (A) | Data Input | Inverting logic input with Schmitt-trigger threshold; tolerant of slow edges and EMI-induced glitches. |
| 3 (GND) | Ground Reference | 0 V return path for all internal circuitry and output current; must be low-inductance connection. |
| 4 (Y) | Inverted Output | 3-state buffered output; sinks or sources up to ±4 mA at 3.3 V while maintaining VOL ≤ 0.45 V / VOH ≥ 2.3 V. |
| 5 (VCC) | Power Supply | Single-supply rail supporting 0.8–3.6 V; includes internal regulation and brown-out detection for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 μA across full VCC range - extends battery life in coin-cell-powered wearables and remote sensors. |
| IOFF partial power-down | Backflow current limited to ±0.75 μA at VCC = 0 V - eliminates need for external blocking diodes in multi-rail systems. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.1 × VCC - rejects noise on long PCB traces or unshielded cables without external RC networks. |
| Overvoltage-tolerant inputs | Accepts 3.6 V inputs regardless of VCC setting - simplifies mixed-voltage interconnect between legacy 3.3 V peripherals and new 1.2 V SoCs. |
| JEDEC-compliant ESD | HBM > 5000 V, CDM > 1000 V - survives handling and assembly without special ESD controls in standard production lines. |
Applications
| Industrial Sensor Interface | Low-Power MCU GPIO Expansion |
|---|---|
Use Scenario: Connecting analog sensor output (e.g., thermistor divider) to a 1.8 V ADC input in a battery-powered environmental monitor. IC Role / Device Role / Timing Role: Inverting buffer with Schmitt-trigger input cleans noisy RC-filtered voltage and translates 3.3 V sensor swing down to 1.8 V logic levels. Use Value: Eliminates external hysteresis comparator and level shifter, reducing BOM count by two components and saving 1.2 mm² PCB area. | Use Scenario: Expanding GPIO count on a Cortex-M0+ microcontroller with limited 3.3 V I/O pins driving multiple SPI slave select lines. IC Role / Device Role / Timing Role: 3-state inverting buffer isolates unused SPI peripherals during bus arbitration, preventing contention on shared MISO/MOSI lines. Use Value: Enables dynamic peripheral enable/disable with <3.6 ns propagation delay, preserving timing margins in 20 MHz SPI systems. |
| Automotive Body Control Module | IoT Edge Node Power Sequencing |
Use Scenario: Driving LED indicators from a 5 V CAN transceiver's status outputs in a 12 V vehicle chassis environment. IC Role / Device Role / Timing Role: Level-shifting buffer with overvoltage-tolerant inputs accepts 5 V logic while powered from 3.3 V MCU rail, with IOFF protection during ignition-off state. Use Value: Avoids risk of backfeed into 3.3 V domain when 5 V transceiver remains powered, meeting ISO 16750-2 load-dump immunity requirements. | Use Scenario: Managing power-up sequence of RF SoC and sensor array in a LoRaWAN end-node where subsystems power on at different times. IC Role / Device Role / Timing Role: Tristate buffer gates communication lines between modules until both are fully powered and initialized. Use Value: Prevents undefined states and latch-up during staggered power application, verified to operate reliably at −40 °C to +125 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | No IOFF; max VCC = 5.5 V; higher ICC (10 μA typical); no Schmitt input | Requires external power sequencing control; unsuitable for partial power-down systems | Select only if 5 V tolerance and higher drive strength (>32 mA) are required and IOFF is not needed. |
| 74LVC1G14GW,125 | Non-inverting Schmitt trigger; no 3-state; same XSON6 package but 6-pin | Lacks output disable function; cannot isolate buses or share signal lines | Choose when noise immunity is critical but tristate control is unnecessary, e.g., clock conditioning or reset debouncing. |
Compared with SN74LVC1G04DBVR and 74LVC1G14GW,125, the 74AUP1G240GX,125 uniquely combines ultra-low ICC, guaranteed IOFF, Schmitt input, and 3-state output in a 5-pin X2SON5 package-making it optimal for space- and power-constrained hot-pluggable subsystems.

FAQ
What is the maximum capacitive load the 74AUP1G240GX,125 can drive while maintaining specified tpd?
The device is characterized up to 30 pF load capacitance. At VCC = 3.3 V and CL = 30 pF, tpd is 6.4 ns (max), confirming reliable operation with typical PCB trace + IC input capacitance. Exceeding 30 pF may increase propagation delay nonlinearly and degrade edge rate due to increased slew limitation.
Does the 74AUP1G240GX,125 support true bidirectional data flow?
No. It is a unidirectional inverting buffer with fixed input (A) and output (Y) terminals. The 3-state output enables bus sharing but does not allow reverse signal transmission. For bidirectional applications, a dedicated bus transceiver such as 74AUP2G241 must be used.
How does the IOFF feature behave when VCC is ramping from 0 V to nominal voltage?
IOFF activates automatically when VCC drops below ~0.2 V and remains active until VCC exceeds ~0.5 V. During this transition, output leakage stays ≤ ±0.75 μA regardless of OE or input voltage, ensuring safe hot-plug operation without external supervision circuitry.
Can the Schmitt-trigger input be disabled to use standard CMOS thresholds?
No. The Schmitt-trigger action is inherent to the input structure and cannot be bypassed or configured. It provides fixed hysteresis (~0.1 × VCC) across the entire operating range, which is essential for noise rejection but precludes precise threshold tuning for analog comparator use cases.
