Product details
Overview
74AUP1G02FX4-7 from Diodes Incorporated is a single two-input positive NOR gate in ultra-low-power AUP CMOS logic, operating from 0.8V to 3.6V supply, delivering ±4mA output drive at 3.0V, featuring IOFF partial power-down protection and Schmitt-trigger inputs with ~250mV hysteresis at 3.0V, deployed in portable battery-powered logic interfacing.
For engineers reviewing the 74AUP1G02FX4-7 datasheet, 74AUP1G02FX4-7 pinout, 74AUP1G02FX4-7 application, or 74AUP1G02FX4-7 equivalent, key selection criteria include supply voltage flexibility (0.8–3.6V), sub-1µA static current, IOFF-enabled system-level power sequencing, and DFN1409-6 footprint compatibility with space-constrained mobile PCB layouts.
Technical Context
This device implements standard Boolean NOR logic (Y = A + B) using advanced ultra-low-power CMOS process technology. Its IOFF circuit actively disables outputs during power-down, blocking reverse current flow between powered and unpowered rails - critical for mixed-voltage domain isolation in modern portable systems.
Schmitt-trigger inputs provide noise immunity with defined hysteresis (~250mV at VCC = 3.0V), enabling robust operation with slow-rising signals from mechanical switches or legacy peripherals. Propagation delay ranges from 1.0ns (typ, 3.3V, CL = 5pF) to 6.4ns (max, 3.3V, CL = 30pF), supporting low-speed control and level-shifting functions without timing closure concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive NOR gate (Y = A + B) |
| Supply Voltage Range | 0.8V to 3.6V - supports direct interface with 1.2V, 1.8V, 2.5V, and 3.3V I/O domains |
| IOFF Support | Enabled - prevents back-current during partial power-down, essential for hot-swap and multi-rail sequencing |
| Output Drive | ±4mA at VCC = 3.0V - sufficient to drive multiple CMOS loads or small capacitive traces |
| Static Supply Current | < 0.9µA (max, 25°C) - enables multi-year battery life in always-on sensor nodes |
| Input Hysteresis | ~250mV at VCC = 3.0V - rejects noise on slow-switching inputs like pushbuttons or open-collector signals |
| Propagation Delay | 1.0ns (typ) to 4.4ns (max) at 3.3V/CL = 5pF - suitable for non-critical timing paths in power management logic |
Pinout & Package
X2-DFN1409-6 chip-scale package: 1.4mm × 0.9mm × 0.4mm, 0.5mm pad pitch, bottom-side thermal pad not electrically connected, land pattern per Diodes Inc. recommended layout (AP02007).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Primary logic input with Schmitt-trigger threshold; must be tied to VCC or GND if unused |
| 2 (B) | Data Input | Secondary logic input with identical Schmitt characteristics; enables flexible gate configuration |
| 3 (GND) | Ground Reference | Return path for all internal circuitry; requires low-inductance connection to system ground plane |
| 4 (NC) | No Connect | Internally unconnected pad - must remain floating or grounded per layout guidelines; no routing allowed |
| 5 (VCC) | Power Supply | Core supply rail; decoupling capacitor (100nF) required within 2mm of this pin |
| 6 (Y) | Data Output | Push-pull CMOS output; supports full rail-to-rail swing and IOFF disable during power-down |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA max enables decades-long shelf life in battery-backed memory retention circuits |
| IOFF partial power-down | Blocks bidirectional current flow when VCC = 0V, allowing safe interconnection with live backplane buses |
| Schmitt-trigger inputs | 250mV typical hysteresis eliminates contact bounce and EMI-induced glitches in mechanical switch interfaces |
| Wide VCC range | 0.8–3.6V operation permits direct use across LPDDR I/O, microcontroller GPIO, and PMIC control rails |
| ESD robustness | 2kV HBM / 1kV CDM rating reduces need for external protection in handheld enclosure designs |
Applications
| Smartphone Power Sequencing | Wearable Sensor Hub Logic |
|---|---|
|
Use Scenario: Coordinating enable/disable timing between PMIC rails and application processor subsystems during sleep/wake transitions. IC Role / Device Role / Timing Role: NOR gate used as active-low OR function to combine multiple wake-up request signals into a single reset-enable line. Use Value: IOFF prevents leakage from powered wake-signal lines into unpowered PMIC domains, eliminating unintended wake events. |
Use Scenario: Debouncing and combining motion-interrupt and button-press signals before routing to MCU interrupt pin. IC Role / Device Role / Timing Role: Single-gate logic element performing signal conditioning and level translation between 1.8V sensor I/O and 3.3V host MCU. Use Value: Schmitt-trigger inputs reject noise from flex-cable coupling and body capacitance, reducing false interrupts by >95%. |
| USB-C Port Controller Interface | Industrial IoT Edge Node Control |
|
Use Scenario: Generating USB port power-enable signal only when both VBUS detection and CC-line negotiation succeed. IC Role / Device Role / Timing Role: NOR gate configured as negative-logic AND to assert enable only when both upstream conditions are low. Use Value: 0.8V minimum VCC allows direct operation from USB PD controller's 0.9V auxiliary rail, eliminating level-shifters. |
Use Scenario: Monitoring dual watchdog timeout signals from redundant microcontrollers in safety-critical monitoring modules. IC Role / Device Role / Timing Role: Fail-safe combiner that asserts system shutdown when either watchdog fails to toggle within window. Use Value: Sub-1µA ICC ensures negligible impact on 10-year battery budget in sealed environmental sensors. |
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 (10µA typ), wider VCC (1.65–5.5V), no IOFF, no Schmitt inputs | Lacks power-domain isolation; unsuitable for partial power-down systems | Select when interfacing with 5V-tolerant logic and IOFF is unnecessary |
| 74AHC1G02GW,125 | Higher speed (2.5ns typ), higher drive (±8mA), no IOFF, no Schmitt inputs, VCC = 2–5.5V | Not rated for sub-1V operation; incompatible with ultra-low-voltage SoC I/O | Prefer for high-speed control paths where 3.3V-only operation and no power sequencing are acceptable |
Compared with SN74LVC1G02DBVR and 74AHC1G02GW,125, the 74AUP1G02FX4-7 uniquely balances ultra-low static power, sub-1V operation, IOFF, and Schmitt inputs - making it the only choice for battery-critical, multi-rail, noise-prone portable logic interfaces.

FAQ
What is the maximum recommended load capacitance for reliable operation?
The device is characterized up to 30pF load capacitance, with propagation delay increasing predictably (e.g., 4.4ns max at 3.3V/5pF vs. 8.5ns max at 3.3V/30pF). For stable operation beyond 30pF, add series resistance to limit slew rate and prevent ringing; Diodes Inc. recommends limiting total node capacitance to ≤50pF with appropriate damping.
Can unused inputs be left floating?
No - unused inputs must be tied to either VCC or GND. Floating inputs cause increased ICC, potential oscillation, and unpredictable output states due to CMOS input stage sensitivity. The datasheet explicitly mandates termination to ensure specified static current and noise immunity performance.
Does the NC pin require any special PCB treatment?
Pin 4 is a true no-connect with no internal bond wire or die attachment. It may be left unconnected or grounded per board-level ESD strategy, but must never be routed to VCC or driven. Diodes Inc. recommends following their AP02007 taping orientation guide and avoiding solder mask openings over this pad to prevent bridging.
How does IOFF behave when VCC = 0V but input voltage is present?
When VCC = 0V, the IOFF circuit forces the output into high-impedance state regardless of input voltage (0–3.6V), limiting leakage current to ≤0.6µA (max, –40°C to +125°C). This prevents back-driving powered downstream logic and avoids latch-up risk in mixed-power-domain systems.
