Product details
Overview
74AHCT1G86QSE-7 from Diodes Incorporated is a single 2-input positive Exclusive-OR gate in SOT353 package, designed for automotive-grade logic applications with AEC-Q100 Grade 1 qualification (-40°C to +125°C), 4.5V–5.5V supply range, ±8mA output drive at 5V, and Schmitt-trigger inputs enabling robust timing in noisy environments. It implements Y = A ⊕ B in standard push-pull CMOS logic.
For engineers reviewing the 74AHCT1G86QSE-7 datasheet, 74AHCT1G86QSE-7 pinout, 74AHCT1G86QSE-7 application, or 74AHCT1G86QSE-7 equivalent, this part supports high-reliability automotive signal conditioning, industrial control interlocks, and noise-immune digital state comparison where precise XOR logic and thermal stability are required.
Technical Context
This device performs the Boolean function Y = A ⊕ B using CMOS technology with Schmitt-trigger inputs that accept slow-rising/falling signals without oscillation, ensuring clean transitions even with marginal edge rates. Its balanced propagation delays (1.0–9.0 ns) and matched high/low drive strength (±8mA) maintain signal integrity across logic states.
Designed for automotive systems, it operates across full Grade 1 temperature range with validated ESD protection (2kV HBM, 1kV CDM) and latch-up immunity (>100mA), while its 5.5V absolute maximum input voltage allows interfacing with higher-voltage peripherals without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input positive XOR (Y = A ⊕ B); enables parity generation, equality detection, and controlled inversion. |
| Supply Voltage Range | 4.5V to 5.5V; compatible with standard 5V automotive and industrial rails without regulation overhead. |
| Output Drive | ±8mA at VCC = 5V; sufficient to drive multiple 74AHCT inputs or small capacitive loads directly. |
| Propagation Delay | 1.0–9.0 ns (CL = 15–50pF); ensures sub-10ns timing resolution for real-time control loops and synchronization. |
| Input Threshold | VIL ≤ 0.8V, VIH ≥ 2.0V at 5V; wide noise margin accommodates voltage droop and EMI in under-hood environments. |
| Operating Temperature | -40°C to +125°C ambient; qualified per AEC-Q100 Grade 1 for engine control, body electronics, and ADAS subsystems. |
| ESD Protection | 2000V HBM, 1000V CDM; exceeds AEC-Q100-002/-011 requirements for assembly and field reliability. |
Pinout & Package
SOT353 (2.15mm × 2.1mm × 1.1mm, 0.65mm pitch) - ultra-compact 5-pin surface-mount package with exposed pad not present; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First XOR operand; Schmitt-triggered for noise immunity and tolerance to slow edges. |
| 2 (B) | Data Input | Second XOR operand; electrically identical to Pin 1, enabling symmetric logic implementation. |
| 3 (Y) | Data Output | Push-pull CMOS output delivering rail-to-rail logic levels with ±8mA sink/source capability. |
| 4 (VCC) | Power Supply | 5V nominal supply input; absolute max 6.5V allows transient overvoltage tolerance. |
| 5 (GND) | Ground Reference | Return path for all internal circuitry and I/O; must be low-impedance for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow or noisy signals (e.g., mechanical switch debouncing, sensor outputs). |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40°C to +125°C ambient, including PPAP and IATF 16949 manufacturing. |
| CMOS low-power consumption | ICC ≤ 40μA max at 5.5V; reduces system-level power budget in always-on modules like gateway ECUs. |
| Input voltage range beyond VCC | VI rated to 6.5V; permits direct interface with 5V-tolerant microcontrollers or legacy 5V peripherals. |
| Lead-free & halogen-free | Fully RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb); meets global automotive environmental mandates. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | Wider VCC range (1.65–5.5V); lower drive (±24mA at 3.3V, ±12mA at 5V); no AEC-Q100 qualification. | Targeted at commercial/industrial 3.3V systems; lacks automotive temperature and reliability validation. | Select when cost-sensitive non-automotive designs require broader voltage flexibility and 3.3V compatibility. |
| 74AHC1G86SE-7 | Same SOT353 package and pinout; wider VCC (2–5.5V); lower drive (±8mA at 5V, but only ±4mA at 3.3V); no Schmitt inputs. | Used in general-purpose 3.3V/5V logic; unsuitable for noisy or slow-edge environments due to standard CMOS inputs. | Choose for non-automotive 5V systems where input slew rate is controlled and AEC-Q100 is unnecessary. |

FAQ
Can the 74AHCT1G86QSE-7 operate reliably at 4.5V minimum supply?
Yes. The device is fully specified from 4.5V to 5.5V, with guaranteed VOH ≥ 3.70V and VOL ≤ 0.55V at 4.5V and -40°C to +125°C. Propagation delay remains within 1.0–9.0 ns across this range, making it suitable for battery-sag conditions in automotive 5V domains.
Does this part require external pull-up resistors on inputs?
No. Inputs feature Schmitt-trigger action with hysteresis (typ. 0.5V), eliminating need for external pull-ups. Unused inputs must be tied to VCC or GND per datasheet recommendation to prevent floating states and excessive ICC.
What is the thermal resistance of the SOT353 package?
The SOT353 package has θJA = 385°C/W (on FR-4, 2oz copper, minimum pad layout) and θJC = 164°C/W. At 5V and 8mA output load, power dissipation stays below 40mW, resulting in <15°C junction rise above ambient-well within safe operating limits.
Is the 74AHCT1G86QSE-7 pin-compatible with other AHCT single-gate devices?
Yes. All Diodes AHCT single-gate SOT353 parts (e.g., 74AHCT1G00, 74AHCT1G04, 74AHCT1G86) share identical 5-pin pinout (A/B/Y/VCC/GND), enabling drop-in replacement across logic families without PCB redesign.
