Product details
Overview
74HCT2G86DC-Q100 from Nexperia is a dual 2-input EXCLUSIVE-OR gate in VSSOP8 package, qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with 4.5 V–5.5 V supply, TTL-compatible inputs, and propagation delay of 11–48 ns at VCC = 4.5 V - used in automotive body control modules for signal-level logic comparison and fault-detection arbitration.
For engineers reviewing the 74HCT2G86DC-Q100 datasheet, 74HCT2G86DC-Q100 pinout, 74HCT2G86DC-Q100 application, or 74HCT2G86DC-Q100 equivalent, this page delivers verified functional role, automotive-grade thermal and ESD specs, exact pin mapping for VSSOP8, and validated alternatives for logic-level XOR replacement in safety-critical vehicle subsystems.
Technical Context
This device implements two independent CMOS-based XOR gates with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V microcontrollers and sensor outputs without level-shifting. Each gate features rail-to-rail output swing and input clamp diodes supporting current-limited overvoltage tolerance.
Its dynamic behavior is characterized by propagation delays (tpd) ranging from 11 ns (typ) to 48 ns (max) across temperature and voltage, with transition times (tt) under 22 ns and power dissipation capacitance (CPD) of 9 pF per buffer - optimized for low-noise, low-power combinatorial logic in CAN/LIN node interface circuits and diagnostic signal validation paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input EXCLUSIVE-OR - performs bitwise inequality detection on two independent input pairs |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10% tolerance |
| Operating Temperature | -40 °C to +125 °C - supports under-hood and powertrain ECUs without derating |
| Input Compatibility | TTL-level - accepts 0.8 V/2.0 V thresholds, eliminating need for external level shifters with 5 V MCU I/O |
| Propagation Delay | 11 ns (typ) to 48 ns (max) at VCC = 4.5 V - ensures timing predictability in real-time diagnostic loops |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD robustness requirements per ISO 10605 |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads (< 15 pF) |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First XOR gate input A - accepts TTL-level signals; clamped to GND/VCC via internal diodes |
| 2 | VCC | Positive supply - must be decoupled locally with 100 nF ceramic capacitor near pin |
| 3 | 1Y | First XOR gate output - drives downstream logic or pull-up/pull-down networks |
| 4 | GND | Ground reference - shared return path for both gates; requires low-inductance PCB connection |
| 5 | 2A | Second XOR gate input A - electrically isolated from 1A; identical electrical characteristics |
| 6 | 2B | Second XOR gate input B - paired with 2A to form second independent XOR function |
| 7 | 2Y | Second XOR gate output - provides parallel logic result without crosstalk or timing skew vs. 1Y |
| 8 | 1B | First XOR gate input B - completes first gate; pin order follows IEC logic symbol layout (Fig. 1) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including HTOL, TC, and ESD stress testing |
| Input clamp diodes | Enable safe interface to voltages exceeding VCC when used with series current-limiting resistors |
| High noise immunity | CMOS architecture with >40% noise margin at VCC = 5 V ensures reliable operation in electrically noisy vehicle harnesses |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transients or hot-plug events |
| Low static current | ICC ≤ 20 μA at VCC = 5.5 V and TA = +125 °C - minimizes quiescent power in always-on vehicle modules |
Applications
| Body Control Module Logic | Powertrain Diagnostic Arbitration |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC2G86DC-Q100 | CMOS-level inputs (VIH = 3.15 V min at VCC = 4.5 V); higher noise margin but requires level shifting for TTL sources | Suitable where all upstream logic is HC-family or 3.3 V systems; not drop-in for 5 V TTL interfaces | Select when interfacing with 3.3 V MCUs or mixed-voltage domains requiring higher VIH threshold |
| SN74LVC2G86DPWR | Wider supply range (1.65–5.5 V); LVTTL-compatible inputs; non-automotive grade (no AEC-Q100) | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules per OEM requirements | Acceptable for infotainment or telematics modules outside AEC-Q100 scope, where cost or supply chain favors TI |
Compared with 74HCT2G86DC-Q100, the HC variant demands higher input voltage compliance and lacks native TTL compatibility, while the LVC part omits automotive qualification - making the HCT version uniquely suited for AEC-Q100-compliant 5 V logic interfacing where reliability and specification alignment are mandatory.

FAQ
What is the maximum recommended supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per AEC-Q100 qualification. Operation above 5.5 V voids automotive qualification and risks parametric shift or accelerated aging, even if within limiting values.
Can this device interface directly with 3.3 V microcontroller outputs?
No - its TTL-compatible inputs require minimum 2.0 V for HIGH recognition at VCC = 5 V, but 3.3 V logic typically drives only ~2.4–2.7 V HIGH under load. A level shifter or resistor divider is required to ensure VIH margin; the 74HC2G86DC-Q100 variant is better suited for 3.3 V domains.
Is the VSSOP8 package lead-free and RoHS compliant?
Yes - the SOT765-1 package uses lead-free matte tin terminal finish and complies with EU RoHS Directive 2011/65/EU and China RoHS, with full material declarations available in Nexperia's compliance portal under document number QG-0000124.
How does the input clamp diode affect external resistor selection?
When interfacing to voltages > VCC (e.g., 12 V sensor signals), a series current-limiting resistor must restrict IVCC or IGND to ≤ ±20 mA per diode. For 12 V input and 5 V VCC, minimum resistance is (12 V − 5.5 V)/20 mA = 325 Ω - 470 Ω is recommended for margin and thermal safety.
