Product details
Overview
74AHC1G86QSE-7 from Diodes Incorporated is an automotive-grade single 2-input positive Exclusive OR (XOR) gate in SOT353 package, operating from 2.0V to 5.5V supply, delivering ±8mA output drive at 5.0V, with AEC-Q100 Grade 1 qualification (-40°C to +125°C), and Schmitt-trigger inputs for noise-immune signal conditioning in engine control modules.
For engineers reviewing the 74AHC1G86QSE-7 datasheet, 74AHC1G86QSE-7 pinout, 74AHC1G86QSE-7 application, or 74AHC1G86QSE-7 equivalent, this device supports high-reliability logic-level translation, differential signal detection, and fault-tolerant status comparison in constrained automotive and industrial PCB layouts.
Technical Context
This XOR gate implements the Boolean function Y = A ⊕ B using advanced CMOS AHC technology, enabling rail-to-rail input tolerance (VI not limited by VCC) and balanced propagation delays (tPD ≤ 8.5ns at 5V/CL=15pF) across temperature extremes. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3V at 3.3V), improving immunity to slow-rising signals in noisy environments.
The device features symmetrical high- and low-drive capability (IOH/ IOL = ±8mA at 5V), low static current (ICC ≤ 40μA over full temp range), and ESD robustness (2kV HBM, 1kV CDM), all within a 2.15mm × 2.1mm SOT353 footprint optimized for space-constrained automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive XOR gate (Y = A ⊕ B) |
| Supply Voltage Range | 2.0V to 5.5V - supports mixed-voltage system interfacing (e.g., 3.3V MCU to 5V sensor bus) |
| Output Drive | ±8mA at VCC = 5V - sufficient to directly drive LED indicators or small capacitive loads without buffering |
| Propagation Delay | 6.8ns max (VCC = 5V, CL = 15pF, TA = −40°C to +125°C) - enables reliable timing in sub-100MHz combinatorial paths |
| Operating Temperature | −40°C to +125°C (Grade 1) - qualified for under-hood automotive applications per AEC-Q100 |
| Input Hysteresis | Typ. 0.3V at VCC = 3.3V - rejects noise on slow-switching signals (e.g., throttle position feedback) |
| ESD Rating | 2000V HBM, 1000V CDM - exceeds AEC-Q100-002/-011 requirements for production reliability |
Pinout & Package
SOT353 (2.15mm × 2.1mm × 1.1mm, 0.65mm pitch) - ultra-compact 5-pin surface-mount package with exposed pad-compatible thermal profile (θJA = 385°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First XOR operand; accepts rail-to-rail inputs independent of VCC level |
| 2 (B) | Data Input | Second XOR operand; Schmitt-triggered for noise margin on slow edges |
| 3 (GND) | Ground Reference | Return path for logic and output current; must be low-impedance for stable switching |
| 4 (Y) | Data Output | Push-pull XOR result; drives high/low actively without external pull-ups |
| 5 (VCC) | Power Supply | CMOS supply rail; decoupling capacitor required within 3mm for transient stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input voltage range | Inputs tolerate −0.5V to VCC + 0.5V - eliminates level-shifter need when interfacing legacy 5V sensors to 3.3V MCUs |
| Low dynamic power consumption | CPD = 10pF at 1MHz - reduces switching current in battery-powered telematics modules |
| Automotive qualification | AEC-Q100 Grade 1, PPAP-capable, IATF 16949 manufacturing - meets OEM sourcing requirements for Tier-1 ECU designs |
| Latch-up immunity | Exceeds 100mA per AEC-Q100-004 - prevents destructive failure during load dump or ESD 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 VCC range (1.65–5.5V); lower ICC (max 10μA); no AEC-Q100 qualification | Not suitable for automotive under-hood use; acceptable for industrial controls with tighter supply margins | Select when cost-sensitive non-automotive designs require extended low-voltage operation down to 1.65V |
| 74AUP1G86GW,125 | Lower VCC range (0.8–3.6V); ultra-low CPD (4.5pF); −40°C to +125°C but not AEC-Q100 certified | Optimized for battery-powered IoT nodes; insufficient for 5V automotive buses or PPAP documentation | Choose for portable medical devices or wearables needing sub-1V logic compatibility and minimal dynamic power |
Compared with SN74LVC1G86DBVR and 74AUP1G86GW,125, the 74AHC1G86QSE-7 uniquely combines AEC-Q100 Grade 1 qualification, 5.5V tolerance, and Schmitt-trigger inputs-making it the only option for safety-critical XOR functions in automotive powertrain systems requiring validated reliability and wide supply headroom.

FAQ
What is the maximum allowable input voltage for the 74AHC1G86QSE-7?
The absolute maximum input voltage is −0.5V to VCC + 0.5V, independent of supply level. This rail-to-rail tolerance allows direct connection to 5V sensors even when VCC = 3.3V, eliminating external level shifters in mixed-voltage systems.
Does the 74AHC1G86QSE-7 require external pull-up or pull-down resistors on inputs?
No. Unused inputs must be tied to VCC or GND per datasheet recommendation, but no external resistors are needed due to internal input structure. The Schmitt-trigger inputs inherently reject noise without external biasing components.
Can the 74AHC1G86QSE-7 drive a 50pF load at 10MHz without signal degradation?
Yes. With tPD ≤ 11.5ns (VCC = 5V, CL = 50pF, TA = −40°C to +125°C) and rise/fall times < 3ns, the device maintains clean edges into 50pF loads up to ~35MHz fundamental frequency-well above 10MHz operation.
Is the SOT353 package of the 74AHC1G86QSE-7 compatible with standard reflow profiles?
Yes. The SOT353 package has Moisture Sensitivity Level 1 per J-STD-020 and is rated for peak reflow temperatures up to 260°C. Standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020) apply without preconditioning.
