Product details
Overview
74LVC2G86RA3-7 from Diodes Incorporated is a dual 2-input XOR gate in X2-DFN1210-8 package, operating from 1.65V to 5.5V with ±24mA output drive at 3.3V, IOFF-enabled partial power-down protection, and Schmitt-trigger inputs (100mV hysteresis at 3.0V). It performs voltage-level shifting and signal isolation in compact portable electronics.
For engineers reviewing the 74LVC2G86RA3-7 datasheet, 74LVC2G86RA3-7 pinout, 74LVC2G86RA3-7 application, or 74LVC2G86RA3-7 equivalent, key selection criteria include supply voltage range, IOFF leakage (<±10μA), propagation delay (0.8–6.0ns across VCC), and DFN1210 thermal resistance (θJA = 395°C/W).
Technical Context
This device implements two independent positive-logic XOR functions (Y = A ⊕ B) using CMOS technology with push-pull outputs. Each gate accepts input voltages up to 5.5V regardless of VCC, enabling robust level translation between mixed-voltage domains.
The integrated IOFF circuit disables outputs during power-down, blocking back-current flow into powered sections. Schmitt-trigger inputs provide noise immunity for slow-rising/falling signals, with hysteresis confirmed at 100mV typical at VCC = 3.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports interoperability across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive moderate capacitive loads without external buffering |
| Propagation Delay | 0.8ns (min) to 6.0ns (max) at VCC = 3.3V - enables timing-critical XOR operations in high-speed digital interfaces |
| IOFF Leakage Current | ±10μA max at TA = +125°C - ensures safe bus isolation during partial power-down sequences |
| Input Hysteresis | 100mV typical at VCC = 3.0V - rejects noise on slow-switching control or sensor-derived inputs |
| ESD Robustness | 2000V HBM, >1000V CDM - meets industrial-grade reliability requirements without external protection |
| Thermal Resistance θJA | 395°C/W - reflects thermal performance in X2-DFN1210-8 package on standard FR-4 PCB |
Pinout & Package
X2-DFN1210-8 package: 1.2mm × 1.0mm × 0.35mm body, 0.3mm lead pitch, exposed thermal pad (no internal connection), 8-terminal surface-mount layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Data Input (Gate 1) | First XOR operand for Gate 1; accepts 0–5.5V regardless of VCC |
| 1B | Data Input (Gate 1) | Second XOR operand for Gate 1; Schmitt-triggered for noise margin |
| 2Y | Data Output (Gate 2) | Push-pull result of Gate 2 (2A ⊕ 2B); active-drive capability ±24mA |
| GND | Ground Reference | Return path for all logic and output currents; connects to PCB ground plane |
| 2A | Data Input (Gate 2) | First XOR operand for Gate 2; electrically identical to 1A/1B |
| 2B | Data Input (Gate 2) | Second XOR operand for Gate 2; supports same voltage and timing specs as 1A/1B |
| 1Y | Data Output (Gate 1) | Push-pull result of Gate 1 (1A ⊕ 1B); fully compatible with 2Y |
| VCC | Supply Voltage | Primary power rail; IOFF activation occurs when VCC = 0V while inputs/outputs remain biased |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent XOR gates | Two fully isolated logic functions in one die-reduces board space vs. discrete solutions |
| IOFF partial power-down support | Prevents destructive back-current flow when VCC is off but I/O lines remain active |
| Schmitt-trigger inputs | 100mV hysteresis at 3.0V enables reliable operation with slow or noisy control signals |
| Wide voltage compatibility | Inputs tolerate up to 5.5V while VCC operates as low as 1.65V-ideal for level-shifting |
| Low dynamic power | Typical Cpd = 20pF at 3.3V/10MHz-minimizes switching power in battery-powered devices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G86DCKR | X2-SON8 (2.0×1.25mm), θJA = 336°C/W, 0.5mm pitch, no exposed pad | Larger footprint; less thermally efficient but easier hand-soldering and probe access | Select when thermal budget allows and assembly process favors larger pitch |
| 74LVC2G86HK3-7 | X2-DFN1410-8 (1.35×1.0mm), θJA = 321°C/W, 0.4mm pitch, same pinout | 0.15mm larger area than RA3 but 74°C/W lower thermal resistance; identical function | Select when improved thermal performance justifies minimal size increase in space-constrained designs |
Compared with SN74LVC2G86DCKR and 74LVC2G86HK3-7, the 74LVC2G86RA3-7 offers the smallest footprint (1.2×1.0mm) and highest integration density, though with elevated thermal resistance-optimal for ultra-compact battery-powered devices where board area dominates thermal design.

FAQ
What is the maximum input voltage tolerance for 74LVC2G86RA3-7?
The inputs accept up to 5.5V regardless of VCC level, enabling use as a level translator from higher-voltage domains (e.g., 5V microcontrollers) to lower-voltage logic (e.g., 1.8V FPGAs). This is specified in the Absolute Maximum Ratings table and confirmed in Recommended Operating Conditions.
Does 74LVC2G86RA3-7 support true bidirectional signal isolation during power-down?
Yes-the IOFF circuit actively disables both outputs when VCC = 0V, limiting leakage current to ±10μA max at +125°C. This prevents back-current flow from live I/O lines into unpowered sections, satisfying partial power-down requirements per JESD78 Class I latch-up immunity.
How does the Schmitt-trigger input improve noise immunity?
Each input exhibits ~100mV hysteresis at VCC = 3.0V, meaning the rising threshold is ~100mV higher than the falling threshold. This prevents oscillation on slow or noisy signals-such as mechanical switch closures or long PCB traces-and eliminates need for external RC filtering.
Can 74LVC2G86RA3-7 be used in place of 74LVC2G86HK3-7 without layout changes?
No-though both share identical pinout numbering and logic function, the X2-DFN1210-8 (RA3) and X2-DFN1410-8 (HK3) packages have different dimensions (1.2×1.0mm vs. 1.35×1.0mm) and pad layouts. The RA3 requires smaller solder pads and 0.3mm pitch, making it non-interchangeable without PCB revision.
