Product details
Overview
74AHC86D-Q100 from Nexperia is an automotive-qualified quad 2-input XOR gate in SO14 (SOT108-1) package, operating from 2.0 V to 5.5 V supply, with CMOS-level inputs, -40 °C to +125 °C temperature range, and overvoltage-tolerant inputs up to 5.5 V - used for logic-level translation and signal integrity control in automotive body electronics and powertrain interface circuits.
For engineers reviewing the 74AHC86D-Q100 datasheet, 74AHC86D-Q100 pinout, 74AHC86D-Q100 application, or 74AHC86D-Q100 equivalent, key selection considerations include AEC-Q100 Grade 1 qualification, input voltage tolerance across mixed-voltage domains, propagation delay under 8.5 ns at 5 V/50 pF, Schmitt-trigger input hysteresis, and SO14 package compatibility with legacy PCB layouts.
Technical Context
This device implements four independent 2-input exclusive-OR logic functions with fully buffered outputs and rail-to-rail CMOS-compatible switching. Each gate features Schmitt-trigger inputs for noise immunity and operates with balanced tPLH/tPHL propagation delays.
It supports mixed-voltage interfacing via overvoltage-tolerant inputs (up to 5.5 V regardless of VCC), enabling use between 3.3 V and 5 V subsystems without level shifters. The logic function follows standard XOR truth table: output HIGH only when inputs differ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input XOR gate; each gate outputs HIGH only when its two inputs differ. |
| Supply Voltage Range | 2.0 V to 5.5 V - enables operation across 3.3 V and 5 V systems without external regulation. |
| Propagation Delay | ≤8.5 ns at VCC = 5.0 V, CL = 50 pF - ensures timing compliance in high-speed digital control loops. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe interfacing with higher-voltage signals in mixed-rail designs. |
| Operating Temperature | -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood automotive applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - provides robust handling during assembly and field operation. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive multiple CMOS loads or moderate capacitive traces. |
Pinout & Package
74AHC86D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, and JEDEC MS-012 compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data input A for gates 1–4 | CMOS-level inputs accepting voltages up to 5.5 V; Schmitt-triggered for noise rejection. |
| 1B, 2B, 3B, 4B | Data input B for gates 1–4 | Independent complementary inputs per gate; tolerant of slow or noisy edges. |
| 1Y, 2Y, 3Y, 4Y | Data output Y for gates 1–4 | Pull-up/pull-down CMOS outputs capable of sourcing/sinking ±8 mA at 4.5 V. |
| VCC (Pin 14) | Positive supply | Primary power rail; decoupling capacitor required within 10 mm for stable switching. |
| GND (Pin 7) | Ground reference | Return path for all internal logic and I/O; must be low-impedance and tied to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| Overvoltage-tolerant inputs | Accepts input signals up to 5.5 V regardless of VCC setting - eliminates need for external level translators. |
| Schmitt-trigger inputs | Provides hysteresis (typically 0.3–0.5 V) to reject noise on slow-rising/falling signals in noisy automotive environments. |
| Low dynamic power dissipation | CPD = 10.0 pF - enables efficient operation at 1 MHz with <1 μW/MHz dynamic power per input. |
| Wide supply range (2.0–5.5 V) | Supports direct integration into both 3.3 V microcontroller peripherals and 5 V sensor interfaces without voltage conversion. |
Applications
| Body Control Module Logic | Powertrain Sensor Interface |
|---|---|
|
Use Scenario: Detecting mismatch between redundant position sensor outputs in door latch or seat motor control. IC Role / Device Role / Timing Role: XOR gate compares dual analog-to-digital converter outputs after conditioning; flags discrepancy as fault signal. Use Value: Enables real-time hardware-level fault detection without MCU intervention, meeting ASIL-B diagnostic coverage requirements. |
Use Scenario: Validating crankshaft and camshaft sensor synchronization in engine management units. IC Role / Device Role / Timing Role: Compares phase-aligned square-wave signals from Hall-effect sensors to verify correct timing relationship. Use Value: Provides deterministic, sub-10 ns timing comparison independent of software latency - critical for misfire detection. |
| LED Driver Enable Logic | Diagnostic Communication Arbitration |
|
Use Scenario: Enabling high-side LED drivers only when both enable and safety-lock signals are asserted. IC Role / Device Role / Timing Role: Implements XOR-based enable gating where output activates only when inputs differ - used as inverted enable logic. Use Value: Adds fail-safe behavior: driver remains off if both control lines are shorted to same state, preventing unintended illumination. |
Use Scenario: Resolving bus arbitration conflicts between two CAN transceiver status indicators in gateway ECUs. IC Role / Device Role / Timing Role: Compares active-low interrupt flags from dual CAN controllers to generate prioritized fault alert. Use Value: Delivers deterministic, zero-software-latency resolution of concurrent diagnostic events - essential for OBD-II compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT86D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), fixed 4.5–5.5 V supply range - no 3.3 V operation. | Required where interfacing legacy 5 V TTL logic; incompatible with 3.3 V-only systems. | Select when interfacing 5 V microcontrollers or legacy peripherals requiring TTL thresholds. |
| SN74LVC2G86DCUR | Single dual-input XOR in US8 package; 1.65–5.5 V supply; lower drive (±24 mA), but no AEC-Q100 qualification. | Not qualified for automotive use; suitable only for industrial or consumer applications. | Choose for space-constrained non-automotive designs needing single-gate flexibility and wider voltage support. |
Compared with 74AHCT86D-Q100, the 74AHC86D-Q100 supports broader supply range and CMOS thresholds, while SN74LVC2G86DCUR offers smaller size and higher drive but lacks automotive qualification and quad integration.

FAQ
Is 74AHC86D-Q100 pin-compatible with standard 74HC86 devices?
Yes - it uses identical SO14 pinout (SOT108-1) and functional mapping as industry-standard 74HC86, but adds AEC-Q100 qualification, extended temperature range (-40 °C to +125 °C), and overvoltage-tolerant inputs up to 5.5 V. No PCB redesign is needed for drop-in replacement in qualified automotive designs.
Can 74AHC86D-Q100 operate reliably at 3.3 V supply?
Yes - it is fully specified from 2.0 V to 5.5 V, with guaranteed VIH/VIL thresholds, propagation delay (≤14.0 ns at 3.3 V/50 pF), and output drive (±4 mA) across the entire range. It interfaces natively with 3.3 V microcontrollers without level shifting.
What is the purpose of Schmitt-trigger inputs in this device?
Schmitt-trigger inputs provide hysteresis (~0.4 V typical) to reject noise on slow or degraded signal edges - critical in automotive wiring harnesses subject to EMI, load dump, or long trace ringing. This prevents false toggling during signal transitions.
Does 74AHC86D-Q100 require external pull-up or pull-down resistors on unused inputs?
No - all inputs have internal protection and defined logic states when floating, but best practice is to tie unused inputs to VCC or GND to prevent noise coupling and minimize ICC. Floating inputs may increase supply current and cause erratic output behavior in high-noise environments.
