Product details
Overview
74AHCT1G86QW5-7 from Diodes Incorporated is an automotive-grade single 2-input positive Exclusive-OR gate in SOT25 package, operating at 4.5V–5.5V supply, delivering ±8mA output drive at 5V, with propagation delay ≤9.0ns (–40°C to +125°C) and AEC-Q100 Grade 1 qualification for under-hood automotive logic applications.
For engineers reviewing the 74AHCT1G86QW5-7 datasheet, 74AHCT1G86QW5-7 pinout, 74AHCT1G86QW5-7 application, or 74AHCT1G86QW5-7 equivalent, key selection criteria include its Schmitt-trigger input tolerance for slow-edge signals, balanced high/low drive capability, latch-up immunity (>100mA), ESD robustness (2kV HBM), and IATF 16949-manufactured supply chain traceability.
Technical Context
This device implements the Boolean function Y = A ⊕ B using CMOS technology with push-pull outputs and Schmitt-trigger inputs-enabling reliable operation with slow-rising/falling waveforms in noisy automotive environments. It supports rail-to-rail input voltage range (–0.5V to VCC + 0.5V) and operates across –40°C to +125°C ambient without derating.
Its logic behavior follows a standard XOR truth table (H/H→L, L/H→H, H/L→H, L/L→L), with matched tPLH/tPHL delays and symmetrical VOH/VOL specs (VOH ≥3.70V @ –40°C to +125°C, VOL ≤0.55V @ same range), ensuring predictable timing in combinatorial logic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input positive Exclusive-OR (Y = A ⊕ B); enables parity generation, signal comparison, and controlled inversion. |
| Supply Voltage Range | 4.5V to 5.5V; compatible with standard 5V automotive and industrial power rails without level-shifting. |
| Output Drive | ±8mA at 5V; sufficient to directly drive multiple 74AHCT inputs or small LEDs without buffering. |
| Propagation Delay | ≤9.0ns max (–40°C to +125°C, CL = 15pF); ensures timing integrity in high-speed control loops. |
| Input Threshold | VIL ≤0.8V, VIH ≥2.0V at 5V; wide noise margin with Schmitt-trigger hysteresis for robust noise immunity. |
| Operating Temperature | –40°C to +125°C ambient (Grade 1); qualified per AEC-Q100 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
SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with moisture sensitivity level 1 and matte tin-plated leads compliant with MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Primary XOR operand input; accepts full-rail voltages (–0.5V to VCC + 0.5V) with Schmitt-trigger hysteresis. |
| 2 (B) | Data Input | Secondary XOR operand input; electrically identical to Pin 1 with matched input thresholds and capacitance. |
| 3 (GND) | Ground Reference | Return path for all internal logic and output current; must be low-impedance to maintain noise immunity. |
| 4 (Y) | Data Output | Push-pull XOR result output; capable of sourcing/sinking ±8mA while maintaining VOH/VOL specs. |
| 5 (VCC) | Power Supply | Positive supply terminal; requires local 100nF ceramic decoupling within 5mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow edge rates (≤20 ns/V) in noisy automotive harnesses without external filtering. |
| Grade 1 temperature rating | Validated operation from –40°C to +125°C ambient, supporting placement near engines, inverters, and power modules. |
| CMOS low-power design | ICC ≤40μA max over full temperature range, minimizing standby current in always-on vehicle modules. |
| Input voltage independence | Inputs functional up to VCC + 0.5V, allowing safe interfacing with higher-voltage sensors or legacy 5V peripherals. |
| Latch-up immunity | Exceeds 100mA per AEC-Q100-004, preventing destructive failure during transient overvoltage events. |

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 supply range (1.65V–5.5V); lower drive (±24mA @ 3.3V); no AEC-Q100 qualification. | Targeted at commercial/industrial 3.3V systems; lacks automotive temperature and reliability validation. | Select when operating below 4.5V or requiring 3.3V compatibility; verify thermal derating for >85°C ambient. |
| 74AHC1G86W5-7 | Same footprint and pinout; wider VCC range (2V–5.5V); higher ICC (≤100μA); non-automotive grade. | Not AEC-Q100 qualified; rated only to +105°C ambient; unsuitable for under-hood deployment. | Use for cost-sensitive non-automotive designs where extended voltage flexibility outweighs qualification requirements. |
Compared with SN74LVC1G86DBVR and 74AHC1G86W5-7, the 74AHCT1G86QW5-7 uniquely combines AEC-Q100 Grade 1 qualification, 4.5V–5.5V rail compatibility, and Schmitt-trigger inputs-making it the only choice for safety-critical automotive XOR functions requiring guaranteed operation at +125°C.

FAQ
Is the 74AHCT1G86QW5-7 pin-compatible with other SOT25-packaged logic gates?
Yes-it shares the standard SOT25 5-pin layout (A-B-GND-Y-VCC) used across Diodes' 74AHCT1Gxx series, enabling drop-in replacement for functionally equivalent gates like 74AHCT1G00 or 74AHCT1G04 in the same package. No PCB redesign is needed when swapping within this family.
Can unused inputs be left floating?
No-unused inputs must be tied to VCC or GND per the datasheet's recommended operating conditions. Floating inputs may cause increased ICC, oscillation, or undefined output states due to CMOS input structure susceptibility to noise and leakage.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50pF load capacitance, with tPD specified at both 15pF and 50pF. Driving >50pF risks exceeding propagation delay limits and increasing dynamic power dissipation; add a buffer stage for loads above this threshold.
Does this part support hot-swap or live-insertion?
No-hot-swap capability is not supported. The absolute maximum ratings specify VI and VO limits relative to GND and VCC, and no power sequencing or current-limiting features are integrated. Power must be applied before signal inputs to avoid violating VI or VO limits.
