Product details
Overview
74AUP2G86RA3-7 from Diodes Incorporated is a dual two-input exclusive OR (XOR) gate in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for battery-powered portable electronics. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and integrates Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V - enabling robust signal integrity in low-voltage, noise-prone mobile interfaces.
For engineers reviewing the 74AUP2G86RA3-7 datasheet, 74AUP2G86RA3-7 pinout, 74AUP2G86RA3-7 application, or 74AUP2G86RA3-7 equivalent, this device is selected for ultra-low static current (<0.9µA), wide-VCC compatibility, and DFN1210-8 packaging optimized for space-constrained PCB layouts in handheld consumer devices.
Technical Context
The 74AUP2G86RA3-7 implements two independent XOR logic functions (Y = A ⊕ B) using push-pull CMOS outputs, with full support for partial power-down via IOFF circuitry that disables outputs and blocks backflow current when VCC = 0V. Its input stage includes Schmitt-trigger action, ensuring reliable switching even with slow-rising/falling signals - critical for interfacing with legacy or low-slew-rate peripherals.
It is characterized over –40°C to +125°C ambient temperature and validated for operation at VCC as low as 0.8V, making it suitable for multi-rail systems where core logic runs at sub-1V while I/O domains operate near 3.3V. Propagation delay ranges from 1.0ns (typ, 3.3V, CL = 5pF) to 9.2ns (max, 3.3V, CL = 30pF), scaling predictably with load capacitance and supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input XOR gate (Y = A ⊕ B); enables parity generation, data comparison, and controlled signal inversion. |
| Supply Voltage Range | 0.8V to 3.6V; supports direct interface with 0.9V/1.2V/1.8V/2.5V/3.3V logic domains without level shifters. |
| IOFF Support | Active at VCC = 0V; prevents damaging back-current flow during partial system power-down - essential for hot-swap and battery-save modes. |
| Static Supply Current | <0.9µA (max, TA = +25°C); extends battery life in always-on sensor or wake-up logic circuits. |
| Output Drive | ±4mA at VCC = 3.0V; sufficient to drive 50Ω transmission lines or fan-out of ≥10 standard AUP loads. |
| Input Hysteresis | ~250mV at VCC = 3.0V; rejects noise up to ±125mV on slow edges - eliminates need for external RC filtering. |
| Package | X2-DFN1210-8 (1.2mm × 1.0mm × 0.35mm, 0.3mm pitch); enables high-density routing and thermal performance (θJA = 395°C/W). |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input A of Gate 1 | First data input to XOR gate 1; accepts 0.8V–3.6V logic levels with Schmitt-trigger threshold. |

| 2Y | Output Y of Gate 2 | Push-pull output of gate 2; sinks or sources up to ±4mA at 3.0V with defined VOH/VOL. |
| GND | Ground Reference | Primary return path for all internal logic and I/O; must be connected to system ground plane. |
| 2A | Input A of Gate 2 | First data input to XOR gate 2; independent of gate 1; shares same electrical specs as 1A/1B. |
| 2B | Input B of Gate 2 | Second data input to XOR gate 2; supports asynchronous operation with gate 1. |
| 1Y | Output Y of Gate 1 | Push-pull output of gate 1; electrically isolated from 2Y; supports independent loading. |
| VCC | Power Supply | Single-supply input for both gates; IOFF activates automatically when VCC = 0V. |

Use Scenario: Detecting keypress combinations (e.g., Fn+Ctrl) in ultrabook keyboard controllers where supply rails vary between 1.2V (core) and 3.3V (I/O). IC Role / Device Role / Timing Role: Dual XOR gate performs real-time bitwise comparison of row/column scan signals to identify simultaneous key actuation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G86DPWR | Wider VCC range (1.65V–5.5V); higher ICC (10µA typ); no IOFF; no Schmitt inputs. | Better suited for 5V-tolerant industrial I/O; unsuitable for sub-1V battery operation or partial power-down. | Select only if interfacing with 5V peripherals and power-down isolation is not required. |

FAQ
What is the minimum operating voltage for reliable XOR function in the 74AUP2G86RA3-7?
The device is fully specified down to 0.8V VCC across –40°C to +125°C, with guaranteed logic operation, propagation delay, and output drive per datasheet Table 6. At 0.8V, tpd is 24.4ns (typ, CL = 5pF), and IOH/IOL remain functional at ±20µA - sufficient for low-speed control signaling in energy-harvesting nodes.
Does the 74AUP2G86RA3-7 require external pull-up or pull-down resistors on unused inputs?
Yes. Per datasheet Note 8, unused inputs must be tied to VCC or GND to prevent floating states that increase ICC and cause unpredictable logic behavior. The Schmitt-trigger inputs do not eliminate this requirement - they only improve noise immunity on actively driven lines.
Can the 74AUP2G86RA3-7 safely interface with 5V logic outputs?
No. Absolute maximum input voltage is VCC + 0.5V (e.g., 4.1V at VCC = 3.6V). Direct connection to 5V signals risks permanent damage. A level-shifter or resistor-divider network is required for 5V-tolerant interfacing - the device itself is not 5V-tolerant.
How does the IOFF feature behave when VCC is ramping during power-up or power-down?
IOFF activates when VCC drops below ~0.2V and remains active until VCC exceeds ~0.4V. During ramp transitions, the output enters high-impedance state before VCC reaches operational threshold, preventing back-current from powered downstream circuits into the unpowered gate - verified per JESD78 latch-up and ESD test conditions.
