Product details
Overview
74LVC1G86QW5-7 from Diodes Incorporated is an automotive-grade single 2-input positive XOR gate in SOT25 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with 5.5V-tolerant inputs and IOFF partial power-down protection. It performs Boolean Y = A ⊕ B and is qualified per AEC-Q100 Grade 1 (–40°C to +125°C) for use in automotive signal routing and voltage-level shifting circuits.
For engineers reviewing the 74LVC1G86QW5-7 datasheet, 74LVC1G86QW5-7 pinout, 74LVC1G86QW5-7 application, or 74LVC1G86QW5-7 equivalent, key selection criteria include its 5.5V input tolerance in mixed-voltage systems, IOFF-enabled backflow prevention during power sequencing, ±24mA drive strength at 3.3V, and guaranteed operation across –40°C to +125°C ambient.
Technical Context
This device implements a non-inverting XOR logic function (Y = A ⊕ B) using CMOS technology, supporting rail-to-rail input and output swing across its full 1.65V–5.5V VCC range. Its IOFF circuit actively disables outputs when VCC = 0V, blocking current flow between powered and unpowered domains.
Propagation delay is specified from 0.5ns (typ, 5V) to 3.7ns (typ, 1.8V), with input transition rate support up to 20 ns/V at 1.8V. Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V), enabling robust interfacing across voltage domains without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic families |
| Input Voltage Tolerance | Up to 5.5V - enables safe connection to higher-voltage signals without clamping diodes |
| IOFF Leakage | ±2 μA max - prevents damaging back-current during partial power-down sequences |
| Output Drive | ±24mA at VCC = 3.0V - sufficient to drive multiple LVC loads or small capacitive buses |
| tPD (Max) | 13.0ns at 1.8V - ensures timing compliance in sub-100MHz digital control paths |
| Operating Temp | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood automotive use |
| ESD HBM | >2000V - exceeds AEC-Q100-002 for robustness in manufacturing and field handling |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First XOR operand; 5.5V-tolerant, compatible with mixed-supply signaling |
| 2 (B) | Data Input | Second XOR operand; identical electrical specs to Pin 1 |
| 3 (GND) | Ground Reference | Return path for all internal logic and output current; must be low-impedance |
| 4 (Y) | Data Output | XOR result (Y = A ⊕ B); push-pull, rail-to-rail, ±24mA capable |
| 5 (VCC) | Supply Voltage | Primary power rail; IOFF activates automatically when VCC = 0V |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | SOT-23-5 package (same pinout), identical logic function and electrical specs; lower thermal resistance (θJA = 172°C/W vs 184°C/W) | No AEC-Q100 qualification; rated only for commercial temperature range (–40°C to +85°C) | Select for cost-sensitive industrial or consumer designs where automotive qualification is not required. |
| 74LVC1G86GW,125 | SC-70-5 package (smaller footprint), same AEC-Q100 Grade 1 rating, but lower output drive (±12mA at 3.0V) | Lower drive limits use in high-capacitance or multi-load scenarios; tighter layout constraints due to 1.25mm × 1.25mm size | Select when board space is critical and load capacitance remains below 20pF with ≤2 fanouts. |
Compared with SN74LVC1G86DBVR and 74LVC1G86GW,125, the 74LVC1G86QW5-7 uniquely combines AEC-Q100 Grade 1 qualification, ±24mA drive, and SOT25 mechanical robustness-making it optimal for automotive body electronics requiring both reliability and signal integrity under thermal stress.

FAQ
What is the maximum clock frequency supported by the 74LVC1G86QW5-7?
The device does not specify a maximum clock frequency, as it is a combinational logic gate-not a sequential element. Its usable toggle rate is determined by propagation delay (tPD ≤13.0ns at 1.8V) and load capacitance. For a 30pF load, maximum reliable toggle frequency is approximately 38MHz (1/(2 × tPD_max)), assuming clean edges and proper termination.
Can the 74LVC1G86QW5-7 be used with a 1.65V supply and 5V inputs simultaneously?
Yes. The 74LVC1G86QW5-7 accepts input voltages up to 5.5V regardless of VCC setting, including at the minimum 1.65V supply. Inputs are overvoltage-tolerant and do not require external clamping. Output swing will be rail-to-rail relative to the 1.65V VCC, so output high = ~1.65V, not 5V.
Does the IOFF feature require external control or configuration?
No. IOFF is fully automatic and requires no external enable signal or configuration. When VCC drops to 0V (or near 0V), the internal circuitry detects loss of supply and immediately disables the output drivers, presenting a high-impedance state and blocking reverse current flow from I/O pins into the unpowered device.
Is the SOT25 package of the 74LVC1G86QW5-7 compatible with standard SOT-23-5 reflow profiles?
Yes. The SOT25 package shares identical footprint, pad layout, and thermal mass characteristics with industry-standard SOT-23-5. It is qualified for moisture sensitivity level 1 and supports standard lead-free reflow profiles (J-STD-020), including peak temperatures up to 260°C for 30 seconds, with no special process adjustments needed.
