Product details
Overview
74AHCT86D-Q100J from Nexperia is an automotive-qualified quad 2-input XOR gate in SO14 (SOT108-1) package, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and propagation delay ≤8.5 ns (CL = 50 pF). It serves as a logic-level combiner in automotive body control modules for door lock arbitration and window position validation.
For engineers reviewing the 74AHCT86D-Q100J datasheet, 74AHCT86D-Q100J pinout, 74AHCT86D-Q100J application, or 74AHCT86D-Q100J equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, overvoltage-tolerant inputs up to 5.5 V, balanced tPLH/tPHL timing, Schmitt-trigger input hysteresis, and SO14 package compatibility with legacy PCB footprints.
Technical Context
This device implements four 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 sensors. Each gate exhibits matched propagation delays (tpd ≤ 8.5 ns at VCC = 5 V, CL = 50 pF) and supports mixed-voltage translation via overvoltage-tolerant inputs rated to 5.5 V regardless of VCC.
It integrates Schmitt-trigger action on all inputs for noise immunity in electrically noisy automotive environments, and meets AEC-Q100 Grade 1 requirements including latch-up immunity >100 mA and ESD robustness (HBM >2000 V, CDM >1000 V). The SO14 package (SOT108-1) provides proven thermal performance with 10.1 mW/K derating above 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input exclusive-OR (XOR); outputs HIGH only when inputs differ - used for parity checking and signal comparison. |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V automotive power rails and stable operation across battery voltage fluctuations. |
| Propagation Delay | ≤8.5 ns at VCC = 5 V, CL = 50 pF - enables reliable timing in sub-100 MHz digital control loops such as LIN bus synchronization. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - matches TTL logic families, allowing direct connection to legacy 5 V MCUs without level-shifting circuitry. |
| Overvoltage Tolerance | Inputs withstand up to 5.5 V independent of VCC - permits safe interfacing with higher-voltage sensors or diagnostics lines in vehicle networks. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin-mounted ECUs exposed to extreme thermal cycling. |
| ESD Protection | HBM >2000 V, CDM >1000 V - exceeds automotive assembly and handling requirements, reducing field failure risk during manufacturing and service. |
Pinout & Package
74AHCT86D-Q100J uses the SO14 plastic small outline package (SOT108-1), 14-pin, 3.9 mm body width, with gull-wing leads and industry-standard 1.27 mm pitch. Pin 1 is marked by a bevelled corner or notch; the package supports reflow soldering and automated optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A (Pins 1, 4, 9, 12) | Data input A for each XOR gate | Accepts TTL-level signals; internally routed to first input of respective XOR cell. |
| 1B, 2B, 3B, 4B (Pins 2, 5, 10, 13) | Data input B for each XOR gate | Accepts TTL-level signals; internally routed to second input of respective XOR cell. |
| 1Y, 2Y, 3Y, 4Y (Pins 3, 6, 8, 11) | Data output for each XOR gate | CMOS push-pull output driving loads up to ±8 mA; compatible with 5 V logic families. |
| VCC (Pin 14) | Positive supply rail | Connects to 4.5–5.5 V automotive power domain; decoupling capacitor required within 10 mm. |
| GND (Pin 7) | Ground reference | Common return path for all gates; must be low-impedance to minimize switching noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling, humidity bias, and mechanical shock testing. |
| Overvoltage-tolerant inputs | Withstand 5.5 V regardless of VCC level - enables safe integration with 5 V sensor buses while powered from regulated 5 V or 3.3 V rails. |
| Schmitt-trigger inputs | Provides >0.4 V hysteresis on all inputs - suppresses false triggering from slow-rising or noisy signals common in automotive wiring harnesses. |
| Low dynamic power dissipation | CPD = 12.0 pF - limits switching current draw in high-frequency applications like PWM feedback logic, reducing thermal load on PCB. |
| SO14 footprint compatibility | Direct replacement for legacy 74LS86 and 74HC86 in existing designs - eliminates need for layout revision or tooling change. |
Applications
| Door Lock Arbitration | Window Position Validation |
|---|---|
|
Use Scenario: Simultaneous lock/unlock requests from driver and passenger door switches are resolved using XOR logic to prevent conflicting actuator commands. IC Role / Device Role / Timing Role: Performs real-time logical comparison between two independent switch inputs to generate a deterministic enable signal for the door lock motor driver. Use Value: Eliminates race conditions and mechanical wear by ensuring only one valid command executes per cycle, with <8.5 ns decision latency. |
Use Scenario: Verifies consistency between Hall-effect sensor output and potentiometer feedback in power window lift systems to detect jamming or sensor failure. IC Role / Device Role / Timing Role: Compares redundant position signals; XOR output HIGH indicates mismatch, triggering safety shutdown before stall torque is reached. Use Value: Enables fail-safe response within one clock cycle of fault detection, meeting ISO 26262 ASIL-B diagnostic coverage requirements. |
| LIN Bus Parity Generation | Ignition Timing Synchronization |
|
Use Scenario: Generates odd parity bit for LIN frame transmission in body control units to ensure data integrity over noisy vehicle networks. IC Role / Device Role / Timing Role: Combines four data bits using cascaded XOR gates to compute parity in hardware, independent of MCU firmware execution. Use Value: Reduces CPU overhead and guarantees deterministic parity calculation time (<35 ns total for 4-bit chain), improving bus throughput. |
Use Scenario: Synchronizes crankshaft and camshaft position signals in engine control modules to determine cylinder firing order. IC Role / Device Role / Timing Role: Detects phase alignment between two digital timing tracks; XOR output pulses indicate misalignment requiring correction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT86PW-Q100 | TSSOP14 package (SOT402-1), 4.4 mm body width, 0.65 mm pitch - smaller footprint but requires tighter stencil design and AOI calibration. | Better thermal resistance (7.3 mW/K derating above 81 °C) suits compact under-dash modules with limited airflow. | Select when board space is constrained and reflow profile supports fine-pitch components; not drop-in for SO14 layouts. |
| 74AHC86D-Q100 | CMOS-level inputs (VIH = 3.85 V min at VCC = 5.5 V) instead of TTL-level - requires compatible 3.3/5 V hybrid signaling or level shifters. | Lower ICC (2 μA typical) and wider VCC range (2.0–5.5 V) suit mixed-supply domains like infotainment power management. | Choose for ultra-low static power or multi-rail systems; avoid if interfacing directly with legacy 5 V TTL peripherals. |
Compared with 74AHCT86PW-Q100, the 74AHCT86D-Q100J offers plug-compatible SO14 mounting and identical electrical behavior but trades off thermal efficiency for legacy manufacturability; versus 74AHC86D-Q100, it delivers guaranteed TTL interoperability at the cost of slightly higher ICC and narrower VCC tolerance.

FAQ
Is 74AHCT86D-Q100J compatible with 3.3 V microcontrollers?
No - this part has TTL-level inputs requiring VIH ≥ 2.0 V, but its minimum VCC is 4.5 V. It cannot operate below 4.5 V and is not designed for direct interface with 3.3 V I/O. Use 74AHC86D-Q100 for 3.3 V–5.5 V mixed-supply systems with CMOS input thresholds.
What is the maximum output drive capability per pin?
Each output drives ±8.0 mA at VCC = 4.5 V while maintaining VOH ≥ 3.70 V and VOL ≤ 0.44 V across -40 °C to +125 °C. Total ICC remains ≤40 μA under static conditions, making it suitable for fan-out to multiple 74AHCT inputs without buffering.
Does the SO14 package include exposed thermal pad?
No - the SOT108-1 (SO14) package used for 74AHCT86D-Q100J has no thermal pad. Thermal management relies on copper pour connected to Pin 7 (GND) and Pin 14 (VCC) on the PCB; junction-to-ambient θJA is 100 K/W per datasheet.
Can unused inputs be left floating?
No - all inputs must be terminated to VCC or GND. Floating inputs cause increased ICC, erratic switching, and potential latch-up due to internal Schmitt-trigger metastability. Tie unused A/B inputs directly to VCC or GND using shortest possible trace.
