Product details
Overview
74AHC1G86SE-7 from Diodes Incorporated is a single 2-input positive-exclusive-OR (XOR) gate in SOT353 package, operating from 2.0V to 5.5V supply, delivering ±8 mA output drive at 5.0V, with Schmitt-trigger inputs for noise immunity, and RoHS-compliant lead-free finish. It performs the Boolean function Y = A ⊕ B in general-purpose logic applications including PC peripherals and consumer audio/video interfaces.
For engineers reviewing the 74AHC1G86SE-7 datasheet, 74AHC1G86SE-7 pinout, 74AHC1G86SE-7 application, or 74AHC1G86SE-7 equivalent, key selection criteria include input voltage thresholds (VIH/VIL), propagation delay (tpd ≤ 8.5 ns at 5V/15pF), output drive capability, thermal resistance (θJA = 430°C/W), and SOT353 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements standard CMOS XOR logic with true positive polarity: output is high only when inputs differ. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3V at VCC = 3.3V), enabling robust operation with slow-rising or noisy signals without external filtering.
Designed for low-power embedded logic, it supports rail-to-rail input/output swing across its full 2.0–5.5V operating range, maintains sub-10 ns propagation delay up to 125°C ambient, and exhibits ultra-low ICC (≤40 µA at 5.5V) with no load-critical for battery-powered and thermally constrained systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0V to 5.5V - enables direct interface with 3.3V and 5V logic families without level shifters |
| Propagation Delay (tpd) | ≤ 8.5 ns at VCC = 5V, CL = 15pF - supports >100 MHz toggle rates in clean signal paths |
| Output Drive | ±8 mA at VCC = 5V - sufficient to drive 10 LVTTL loads or one 50Ω transmission line |
| Input Hysteresis | Typ. 0.3V at VCC = 3.3V - rejects noise spikes <300 mV on slow edges without external RC |
| Power Dissipation Capacitance | 12 pF at f = 1 MHz - determines dynamic power: P = Cpd × V² × f ≈ 0.3 mW at 3.3V/1MHz |
| ESD Protection | HBM >2000V, CDM >1000V - exceeds IEC 61000-4-2 Level 2 for board-level handling safety |
Pinout & Package
SOT353 (5-pin small outline transistor) package: 1.35 mm × 2.20 mm × 0.95 mm body height, lead-free matte tin finish, JEDEC-compliant footprint with 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First XOR operand; accepts 0–VCC logic levels with Schmitt-trigger hysteresis |
| B | Data Input | Second XOR operand; electrically identical to Pin A, fully interchangeable |
| GND | Ground Reference | Return path for all internal currents; must be connected before VCC to avoid latch-up |
| Y | Data Output | Push-pull CMOS output; drives high/low actively; no pull-up required |
| VCC | Supply Voltage | Primary power rail; decoupling capacitor (100 nF) recommended within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable switching with slow or noisy signals (e.g., mechanical switch debouncing without RC network) |
| Wide supply range (2.0–5.5V) | Eliminates need for separate voltage regulators in mixed-supply systems (e.g., 3.3V MCU + 5V sensor interface) |
| Low ICC (≤40 µA) | Reduces quiescent current in always-on logic monitoring circuits (e.g., wake-on-event detection) |
| RoHS-compliant & halogen-free | Meets EU Directive 2002/95/EC and IPC-1752A Tier 1 reporting requirements for industrial and medical products |
Applications
| PC Peripherals Interface | Consumer Audio Signal Routing |
|---|---|
Use Scenario: Logic-level translation between USB hub controller (3.3V) and legacy PS/2 keyboard interface (5V). IC Role / Device Role / Timing Role: XOR gate used as controlled inverter to condition bidirectional data strobes. Use Value: Eliminates discrete resistor networks while maintaining signal integrity across voltage domains via rail-compatible I/O. |
Use Scenario: Mute/unmute control path in portable Bluetooth speaker with analog audio path and digital control MCU. IC Role / Device Role / Timing Role: XOR generates inverted mute enable signal synchronized to MCU GPIO edge transitions. Use Value: Sub-10 ns propagation ensures zero audible click during mute transitions; Schmitt inputs reject EMI from nearby RF sections. |
| Digital Camera Sensor Sync | Industrial Encoder Quadrature Decoding |
Use Scenario: Edge alignment of image sensor frame sync and pixel clock in compact camera module. IC Role / Device Role / Timing Role: XOR compares two phase-shifted clocks to generate precise timing window for exposure trigger. Use Value: 8.5 ns max tpd ensures sub-pixel timing accuracy; low Cpd minimizes clock loading on high-frequency sensor clocks. |
Use Scenario: Direction detection from quadrature-encoded motor position feedback in HVAC blower control. IC Role / Device Role / Timing Role: XOR computes direction bit from A/B channel transitions in real time. Use Value: Schmitt inputs tolerate long cable runs (>1 m) with unshielded encoder wiring; operates reliably at -40°C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | Lower VCC min (1.65V); higher max output drive (±32 mA at 3.3V); no Schmitt inputs | Preferred for 1.8V systems or high-drive fanout; unsuitable for slow/noisy inputs without external conditioning | Select when interfacing with 1.8V FPGAs or driving multiple LVC loads; avoid where input slew rate <1 V/ns |
| 74AUP1G86GW,125 | Ultra-low ICC (≤0.9 µA); slower tpd (max 13.2 ns at 3.0V); same 2.0–5.5V range and Schmitt inputs | Optimized for battery life over speed; suitable for IoT sensor nodes with infrequent logic evaluation | Select for coin-cell-powered devices requiring <1 µA standby; accept 30% longer delay for 98% ICC reduction |
Compared with SN74LVC1G86DBVR and 74AUP1G86GW,125, the 74AHC1G86SE-7 uniquely balances Schmitt noise immunity, 5V tolerance, and sub-10 ns speed-making it optimal for industrial control and mixed-voltage consumer interfaces where signal integrity and voltage flexibility are jointly critical.

FAQ
What is the maximum operating temperature for continuous use?
The 74AHC1G86SE-7 is rated for continuous operation from –40°C to +125°C ambient temperature. Junction temperature must not exceed +150°C; with θJA = 430°C/W in SOT353, power dissipation should remain below 58 mW under worst-case conditions to maintain safe thermal margin.
Can unused inputs be left floating?
No. Unused inputs must be tied to VCC or GND per datasheet Note 3. Floating inputs may cause increased ICC, oscillation, or unpredictable output states due to CMOS input stage sensitivity. For this single-gate device, both A and B are functional inputs; if only one is used, the other must be fixed to a valid logic level.
Is the SOT353 package compatible with reflow soldering per J-STD-020?
Yes. The SOT353 package meets JEDEC J-STD-020D moisture sensitivity level (MSL) 1, allowing unlimited floor life and standard Pb-free reflow profiles (peak 260°C, 20–40 sec). Diodes Inc. AP02001 pad layout is optimized for void-free solder joints using Type 3 solder paste.
Does this device support hot-swap or live-insertion?
No. The 74AHC1G86SE-7 lacks hot-swap protection circuitry. Power sequencing must follow VCC-before-inputs and GND-before-VCC guidelines to prevent latch-up. For hot-swap applications, external series resistors (≥100 Ω) and TVS diodes are required on all I/O lines.
