Product details
Overview
74LVC1G86QSE-7 from Diodes Incorporated is an automotive-grade single 2-input positive XOR gate in SOT353 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with 5.5V-tolerant inputs and IOFF partial power-down protection. It performs Boolean Y = A ⊕ B and is used for voltage level shifting and signal isolation in Grade 1 automotive control modules.
For engineers reviewing the 74LVC1G86QSE-7 datasheet, 74LVC1G86QSE-7 pinout, 74LVC1G86QSE-7 application, or 74LVC1G86QSE-7 equivalent, key selection criteria include its AEC-Q100 qualification, -40°C to +125°C operation, 5.5V input tolerance, IOFF leakage <±2μA, and propagation delay of 2.3ns (typ) at 3.3V.
Technical Context
This device implements a non-inverting exclusive-OR logic function with push-pull CMOS output stage, supporting mixed-voltage interfacing via 5.5V-tolerant inputs while powered from as low as 1.65V. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow.
Designed for automotive Grade 1 environments, it meets AEC-Q100 stress tests including >2000V HBM ESD, >1000V CDM ESD, and >100mA latch-up immunity. Propagation delay ranges from 1.9ns (5V) to 3.7ns (1.8V), with consistent 18pF power dissipation capacitance across supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Positive 2-input XOR (Y = A ⊕ B); enables parity generation, comparator enable, and controlled inversion |
| Supply Voltage Range | 1.65V to 5.5V; supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC; allows safe connection to higher-voltage buses without level shifters |
| IOFF Leakage | ±2μA max at 0V VCC; prevents damaging current backflow during partial power-down sequences |
| Output Drive | ±24mA at 3.3V; sufficient to drive multiple LVC loads or small capacitive traces directly |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First XOR operand; 5.5V-tolerant, compatible with higher-voltage control signals |
| 2 (B) | Data Input | Second XOR operand; independently 5.5V-tolerant, enabling asymmetric voltage domain bridging |
| 3 (GND) | Ground Reference | Return path for logic and output currents; must be low-impedance to maintain noise margin |
| 4 (Y) | Data Output | Push-pull CMOS output; drives high/low actively; supports fan-out to ≥10 LVC loads at 3.3V |
| 5 (VCC) | Supply Voltage | Primary power rail; IOFF activation occurs when VCC = 0V, disabling output regardless of input states |

Applications
| Automotive Body Control Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Isolating wake-up signals between always-on microcontroller and powered-down CAN transceiver during sleep mode. IC Role / Device Role / Timing Role: XOR gate configured as controlled pass-through using one input as enable; IOFF prevents signal corruption during VCC ramp-down. Use Value: Eliminates need for external MOSFET isolators, reducing BOM count and PCB area while maintaining AEC-Q100 compliance. | Use Scenario: Converting differential encoder quadrature signals into direction-indicating logic for PLC motion control inputs. IC Role / Device Role / Timing Role: XOR performs real-time phase comparison between A/B channels; sub-3ns propagation ensures accurate direction detection at >100kHz edge rates. Use Value: Enables direct interface of 5V encoders to 3.3V FPGA I/O banks without discrete level-shifting components. |
| Power Management Sequencing | Automotive Infotainment Subsystem |
Use Scenario: Generating reset assertion windows during multi-rail power-up sequencing in ADAS domain controllers. IC Role / Device Role / Timing Role: XOR compares delayed and undelayed enable signals to create precise pulse-width reset triggers. Use Value: Provides deterministic, temperature-stable timing window generation without RC networks or dedicated sequencer ICs. | Use Scenario: Enabling/disabling audio amplifier mute lines based on Bluetooth pairing status and system power state. IC Role / Device Role / Timing Role: XOR combines user-initiated mute command with hardware fault flag to generate fail-safe mute control. Use Value: Ensures amplifier remains muted during brown-out or communication loss, preventing pop-noise and speaker damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | TI part in SOT-23-5 package; identical logic function and voltage specs but lacks AEC-Q100 qualification | Not suitable for automotive production; acceptable for industrial prototyping or non-safety-critical consumer designs | Select only if AEC-Q100 is not required and SOT-23-5 footprint compatibility is prioritized |
| 74LVC1G86GW,125 | Nexperia part in TSOP-5 package; matches AEC-Q100 Grade 1 and 5.5V input tolerance, but has higher 3.5ns tPD (typ) at 3.3V | Marginally slower timing response; may limit use in >80MHz clock-domain crossing applications | Choose when TSOP-5 mounting preference exists and 1.2ns timing margin is acceptable |
Compared with SN74LVC1G86DBVR and 74LVC1G86GW,125, the 74LVC1G86QSE-7 uniquely combines AEC-Q100 Grade 1 qualification, SOT353 space efficiency, and 2.3ns propagation delay - making it optimal for compact, high-reliability automotive signal routing where timing and qualification are jointly critical.

FAQ
Is the 74LVC1G86QSE-7 pin-compatible with standard SOT23-5 logic gates?
No - the 74LVC1G86QSE-7 uses SOT353 (5-pin, 0.65mm pitch), which has different pin spacing and layout than SOT23-5 (0.95mm pitch). Pin 1–5 mapping matches functional roles (A, B, GND, Y, VCC), but mechanical fit requires board redesign. Always verify land pattern against Diodes' SOT353 outline drawing AP02007.
Can this XOR gate operate reliably at 1.65V supply while driving a 15pF load?
Yes - at 1.65V, the device guarantees tPD ≤13.0ns (max) and VOL ≤0.70V with 4mA sink current, sufficient for driving 15pF loads at frequencies below 20MHz. The 18pF CPD value confirms internal switching capacitance is low enough to avoid excessive dynamic power at this voltage.
What is the maximum allowable input voltage when VCC = 0V?
Per Absolute Maximum Ratings, VI may reach -0.5V to 6.5V regardless of VCC state. With VCC = 0V, inputs remain tolerant up to 5.5V (as specified in Recommended Operating Conditions), and IOFF ensures output is high-impedance - preventing current injection into the powered-down die.
Does the 74LVC1G86QSE-7 support hot insertion in live backplanes?
No - while IOFF protects against back-current during power-down, the device lacks explicit hot-swap control features like slew-rate limiting or undervoltage lockout. Its 5.5V input tolerance helps withstand transient overvoltage during insertion, but full hot-plug capability requires external protection circuitry per system-level requirements.
