Product details

Overview

74AUP1G86FS3-7 from Diodes Incorporated is a single 2-input exclusive-OR (XOR) gate in ultra-low-power CMOS logic, designed for battery-powered portable electronics. It operates from 0.8V to 3.6V, delivers ±4mA output drive at 3.0V, features Schmitt-trigger inputs with ~250mV hysteresis at V_CC = 3.0V, and supports partial power-down via IOFF circuitry to prevent backflow current. It is used in signal-level logic comparison and data path control in compact consumer devices.

For engineers reviewing the 74AUP1G86FS3-7 datasheet, 74AUP1G86FS3-7 pinout, 74AUP1G86FS3-7 application, or 74AUP1G86FS3-7 equivalent, key selection criteria include supply voltage flexibility (0.8–3.6V), low ICC (<0.9µA typical), IOFF-enabled system power sequencing, and DFN0808-4 package compatibility with high-density PCB layouts.

Technical Context

This device implements the Boolean function Y = A ⊕ B using advanced ultra-low-power (AUP) CMOS process technology. Its Schmitt-trigger inputs tolerate slow-rising/falling signals-critical for noisy or RC-filtered interfaces-and provide consistent switching thresholds across voltage and temperature.

The IOFF feature actively disables outputs during partial power-down, blocking current flow between powered and unpowered domains. This enables safe hot-insertion and multi-rail system partitioning without external isolation components.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8V to 3.6V - Enables direct interface with modern low-voltage microcontrollers, sensors, and RF ICs without level-shifting.
Output Drive	±4mA at 3.0V - Sufficient to drive multiple standard CMOS loads or short PCB traces without buffering.
Static Current (I_CC)	<0.9µA typical - Minimizes quiescent drain in always-on subsystems like wake-up logic or real-time status monitoring.
Input Hysteresis	~250mV at V_CC = 3.0V - Rejects noise on slow-switching inputs (e.g., mechanical switches, analog-sensed thresholds).
Propagation Delay	2.3ns typical (V_CC = 1.2V, C_L = 5pF) - Supports >100MHz toggle rates in low-power signal routing paths.
IOFF Leakage	<0.6µA max at 3.6V - Ensures negligible current leakage when V_CC is off but I/O pins remain biased.
ESD Rating	2kV HBM / 1kV CDM - Meets industrial-grade robustness requirements for handheld and portable assembly environments.

Pinout & Package

X2-DFN0808-4 (0.8mm × 0.8mm × 0.35mm, 0.5mm diamond pad pitch) - ultra-compact leadless package optimized for space-constrained mobile and wearable PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1	A Input	First XOR operand input; Schmitt-triggered for noise immunity on asynchronous signals.
2	GND	Ground reference for logic and power domains; must be low-impedance for stable IOFF operation.
3	Y Output	Push-pull XOR result output; capable of sourcing/sinking up to ±4mA at 3.0V.
4	V_CC	Primary supply rail; IOFF activates automatically when V_CC drops below ~0.3V.

Key Features

Feature	Design Value
Ultra-low static power	I_CC < 0.9µA ensures sub-microwatt standby consumption-ideal for coin-cell or energy-harvesting systems.
IOFF partial power-down	Prevents damaging back-current flow when V_CC is de-energized while other system rails remain active.
Schmitt-trigger inputs	250mV hysteresis at 3.0V eliminates chatter on slow or noisy inputs-no external RC filtering required.
Wide V_CC range	0.8–3.6V operation supports direct interfacing with 1.2V, 1.8V, 2.5V, and 3.3V logic families without translation.
Lead-free & RoHS/Green	Fully compliant with EU RoHS 2 and halogen/antimony-free standards (<900ppm Br+Cl, <1000ppm Sb).

Applications

USB-C Port Status Detection

Low-Power Sensor Data Validation

Use Scenario: Detecting cable orientation or accessory presence in USB-C receptacles using differential ID pin states.

IC Role / Device Role / Timing Role: XOR compares two ID pin voltages to generate orientation flag; operates at 1.2V from USB-C VCONN rail.

Use Value: Eliminates need for discrete comparators or microcontroller GPIO polling-reduces BOM count and sleep-mode current by >2µA.

Use Scenario: Validating consistency between redundant environmental sensor readings (e.g., temperature + humidity cross-check).

IC Role / Device Role / Timing Role: XOR computes bit-wise parity of sensor output words; triggers alert if mismatch exceeds threshold.

Use Value: Performs real-time fault detection in <5ns with zero CPU intervention-preserves MCU sleep cycles and extends battery life.

Wearable Motion Trigger Logic

IoT Button Debounce & Edge Detection

Use Scenario: Generating wake-up pulses from accelerometer interrupt combinations (e.g., tap + orientation change).

IC Role / Device Role / Timing Role: XOR combines two asynchronous motion-interrupt signals to produce clean edge-triggered wake event.

Use Value: Schmitt-trigger inputs reject EMI-induced glitches on flex-cable routed interrupts-reduces false wake-ups by >90%.

Use Scenario: Converting mechanical switch bounce into clean digital edges for BLE beacon transmission control.

IC Role / Device Role / Timing Role: XOR compares delayed and undelayed switch signals to detect true transitions; driven from 1.8V coin-cell supply.

Use Value: Achieves hardware-level debounce with <1µA total current-enables 10-year button lifetime on CR2032 cells.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input XOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G86DBVR	Wider V_CC range (1.65–5.5V); no Schmitt inputs; higher I_OH/I_OL (±32mA @ 3.3V)	Better suited for driving heavier capacitive loads or interfacing with 5V legacy peripherals	Select when higher drive strength or 5V tolerance is required; avoid if sub-1V operation or noise immunity is critical.
74AHC1G86SE-7	Higher speed (t_pd = 1.9ns typ @ 3.3V); no IOFF; V_CC min = 2.0V	Optimized for high-speed clock/data path XOR in non-battery applications	Choose for timing-critical paths where 0.8–1.8V operation or partial power-down is unnecessary.

Compared with SN74LVC1G86DBVR and 74AHC1G86SE-7, the 74AUP1G86FS3-7 uniquely balances ultra-low voltage operation (down to 0.8V), sub-µA static current, and IOFF-enabled power domain isolation-making it the only choice for energy-constrained, multi-rail portable designs requiring robust noise immunity.

FAQ

What is the minimum operating voltage for reliable XOR functionality?

The 74AUP1G86FS3-7 is fully specified down to 0.8V V_CC, with guaranteed logic thresholds, propagation delay, and output drive at that voltage. At 0.8V, t_pd is 21.2ns (CL = 5pF), VIH/VIL scale linearly with V_CC, and IOFF remains functional-enabling direct use with emerging sub-1V SoCs and energy-harvesting PMICs.

How does the IOFF feature behave during power sequencing?

IOFF activates automatically when V_CC falls below ~0.3V, placing both input and output terminals in high-impedance state with leakage <0.6µA. This prevents current backflow from powered downstream logic into the unpowered gate-even if A, B, or Y pins are held at 1.8V or 3.3V-ensuring safe multi-rail power-up/down sequences.

Can Schmitt-trigger inputs be disabled or bypassed?

No. The Schmitt-trigger action is inherent to the input stage design and cannot be disabled. It provides fixed hysteresis (~250mV at 3.0V) across all operating voltages and temperatures, ensuring consistent noise rejection without external components or configuration overhead.

Is the X2-DFN0808-4 package compatible with standard reflow profiles?

Yes. The X2-DFN0808-4 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C). Its 0.5mm diamond pad pitch requires stencil aperture design per Diodes' AP02001 guidelines, but no special thermal profiling is needed beyond standard Class 3 assembly practices.
