Product details
Overview
74AUP1G02SE-7 from Diodes Incorporated is a single 2-input positive NOR gate in SOT353 package, designed for ultra-low-power logic in battery-operated systems. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and includes Schmitt-trigger inputs with ~250mV hysteresis at 3.0V for noise immunity in portable electronics.
For engineers reviewing the 74AUP1G02SE-7 datasheet, 74AUP1G02SE-7 pinout, 74AUP1G02SE-7 application, or 74AUP1G02SE-7 equivalent, key selection criteria include supply voltage flexibility (0.8V–3.6V), sub-1µA static current, IOFF-enabled system-level power gating, and verified Schmitt-trigger input robustness against slow signal edges in space-constrained mobile designs.
Technical Context
This device implements standard Boolean NOR logic (Y = A + B) using advanced ultra-low-power CMOS process. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe integration into mixed-voltage or hot-swap subsystems.
The Schmitt-trigger inputs provide defined switching thresholds-typically 0.7×VCC for VIH and 0.3×VCC for VIL-with 250mV hysteresis at 3.0V, ensuring reliable operation with slow-rising/falling signals common in low-speed control interfaces and sensor conditioning paths.
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 |
| Static Supply Current (ICC) | < 0.9µA at 25°C - enables multi-year battery life in always-on sensor nodes and wearables |
| Output Drive Strength | ±4mA at VCC = 3.0V - sufficient to drive multiple 74AUP inputs or small capacitive loads (≤15pF) with <4.4ns propagation delay |
| IOFF Leakage Current | ≤0.6µA at 3.6V - ensures negligible current flow when powered down, critical for partial-power-down architectures |
| Input Hysteresis | ~250mV at VCC = 3.0V - rejects noise on slow-switching control lines (e.g., mechanical switch debouncing, GPIO wake-up) |
| Propagation Delay (tpd) | 2.2ns typical at 3.3V/CL=5pF - balances speed and power for low-frequency control logic, not high-speed data paths |
| ESD Protection | 2kV HBM, 1kV CDM - meets IEC 61000-4-2 Level 2 for handheld device front-end robustness |
Pinout & Package
SOT353 (2.15mm × 2.1mm × 1.1mm, 0.65mm pitch) - leadless surface-mount package with exposed pad thermal path; compatible with standard reflow profiles and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal logic and output stages; must be connected to system ground plane for stable operation and ESD discharge path |
| 2 | B | Second logic input; Schmitt-triggered, tolerant of slow edges and noise up to 250mV hysteresis |
| 3 | A | First logic input; identical electrical behavior to Pin 2; both inputs require explicit biasing (VCC or GND) when unused |
| 4 | VCC | Positive supply rail; supports 0.8V–3.6V operation; decoupling capacitor (100nF) recommended within 2mm of this pin |
| 5 | Y | Inverting NOR output; push-pull structure delivers full rail-to-rail swing and drives capacitive loads ≤30pF with predictable timing |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Ultra-Low-Power CMOS | Enables sub-1µA quiescent current in always-on circuits, extending battery life in IoT edge sensors and remote controls |
| IOFF Partial Power-Down Support | Prevents damaging back-current flow when VCC is removed while other system rails remain active, simplifying power sequencing |
| Schmitt-Trigger Inputs | Eliminates need for external RC debounce networks on mechanical switches or noisy analog sensor outputs |
| Wide Supply Range (0.8V–3.6V) | Allows direct use across legacy 1.2V SoC I/O, modern 1.8V/2.5V FPGAs, and 3.3V microcontrollers without voltage translation |
| Lead-Free & Halogen-Free Construction | Fully RoHS 3 compliant (2015/863/EU) and "Green" certified (<900ppm Br+Cl, <1000ppm Sb), meeting automotive and medical regulatory requirements |
Applications
| Smartphone Power Sequencing | Wearable Sensor Interface |
|---|---|
Use Scenario: Controlling enable/disable sequencing of PMIC rails during sleep/wake transitions in smartphones. IC Role / Device Role / Timing Role: NOR gate acts as a hardware OR-combiner for multiple wake-source signals (e.g., RTC alarm, touch interrupt, BLE packet arrival) to assert system reset or power-on request. Use Value: IOFF prevents backfeed from active 1.8V sensor bus into dormant 0.8V core domain, eliminating risk of latch-up during state transitions. | Use Scenario: Debouncing mechanical buttons and translating analog sensor thresholds (e.g., accelerometer tilt detection) in fitness trackers. IC Role / Device Role / Timing Role: Schmitt-trigger inputs convert slow, noisy analog comparator outputs or switch closures into clean digital logic levels for MCU GPIO sampling. Use Value: Built-in 250mV hysteresis eliminates external RC components and firmware polling loops, reducing BOM count and firmware complexity. |
| SSD Controller Glue Logic | Industrial PLC Input Conditioning |
Use Scenario: Generating status flags (e.g., "thermal warning active") by combining multiple temperature sensor alerts in NVMe SSD modules. IC Role / Device Role / Timing Role: Single-gate NOR performs real-time logical OR of independent thermal shutdown signals before feeding to controller interrupt line. Use Value: Sub-1µA ICC allows continuous monitoring without impacting SSD standby power budget; 3.3V-compatible output directly interfaces with controller's 3.3V-tolerant GPIO. | Use Scenario: Level-shifting and noise filtering for 24V industrial field inputs connected to 3.3V microcontroller ADC or GPIO pins. IC Role / Device Role / Timing Role: Used as input buffer after optocoupler or voltage divider, providing clean digital signal conditioning before PLC logic execution. Use Value: 0.8V–3.6V supply range permits direct connection to isolated 3.3V logic rails; 2kV HBM rating withstands ESD events common in factory-floor environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Higher ICC (1µA typ), no IOFF, 1.65V–5.5V supply range | Lacks partial power-down capability; requires external isolation for mixed-rail systems | Select when operating above 3.6V or when IOFF is unnecessary and cost is primary driver |
| NC7SZ02P5X | Lower drive (±2.6mA at 3.3V), no Schmitt inputs, 1.65V–5.5V supply | Requires external hysteresis for noisy inputs; unsuitable for sub-1.65V battery operation | Choose for cost-sensitive consumer devices where input signals are already clean and supply ≥1.65V |
Compared with SN74LVC1G02DBVR and NC7SZ02P5X, the 74AUP1G02SE-7 uniquely combines ultra-low ICC (<0.9µA), IOFF, Schmitt inputs, and 0.8V operation-making it the only option for energy-critical, mixed-voltage, or noise-prone embedded control functions.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74AUP1G02SE-7?
The device is fully specified from 0.8V to 3.6V. At 0.8V, propagation delay increases to 17.0ns (CL=5pF), but logic thresholds and output drive remain functional per datasheet Table 3. Operation below 0.8V is not characterized and may result in undefined output states or increased ICC.
Can unused inputs be left floating?
No. Per datasheet Note 8, unused inputs must be tied to VCC or GND. Floating inputs cause excessive ICC due to intermediate voltage levels turning on both NMOS and PMOS transistors in the input stage, increasing power consumption and potentially causing oscillation or latch-up.
Does the 74AUP1G02SE-7 support hot insertion or live board swapping?
Yes-its IOFF feature actively disables outputs when VCC = 0V, preventing back-current flow from powered system buses into the unpowered device. This enables safe hot-plug operation in modular systems, provided all other pins (inputs/outputs) remain within absolute maximum ratings (–0.5V to VCC+0.5V).
How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?
The Schmitt-trigger provides hysteresis (~250mV at 3.0V), meaning the input threshold rises to ~2.0V for a low-to-high transition and falls to ~1.75V for high-to-low. This prevents multiple toggles when noise causes the input voltage to hover near a single threshold, making it ideal for debouncing switches or interfacing with slow analog comparators.
