Product details
Overview
74LVC1G86SE-7 from Diodes Incorporated is a single 2-input XOR gate in SOT353 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 the Boolean function Y = A ⊕ B and is used for voltage-level shifting and signal isolation in portable computing peripherals.
For engineers reviewing the 74LVC1G86SE-7 datasheet, 74LVC1G86SE-7 pinout, 74LVC1G86SE-7 application, or 74LVC1G86SE-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), 5.5V input tolerance for mixed-voltage interfacing, IOFF-enabled power-down isolation, propagation delay ≤6.5ns at 3.3V, and SOT353 footprint compatibility with space-constrained PCB layouts.
Technical Context
The 74LVC1G86SE-7 implements a standard CMOS XOR logic function with push-pull output stage, supporting rail-to-rail input voltage range up to 5.5V independent of VCC. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow between powered and unpowered domains.
It operates across industrial temperature range (−40°C to +125°C) with guaranteed switching performance: tPD ≤6.5ns (max) at VCC = 3.3V and TA = −40°C to +125°C, and supports direct TTL-level interfacing due to VIH/VIL thresholds aligned with legacy logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input exclusive OR (Y = A ⊕ B); enables parity generation, comparator, and controlled inversion in digital control paths. |
| Supply Voltage Range | 1.65V to 5.5V; allows direct integration into multi-rail systems (e.g., 1.8V/3.3V/5V domains) without level shifters. |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC; permits safe interfacing with higher-voltage controllers while VCC is at 1.65V–3.3V. |
| Output Drive Strength | ±24mA at VCC = 3.3V; sufficient to drive multiple LVC loads or small capacitive traces without buffering. |
| Propagation Delay | ≤6.5ns max at VCC = 3.3V, TA = −40°C to +125°C; ensures timing compliance in sub-100MHz synchronous logic paths. |
| IOFF Leakage Current | ±200μA max at VCC = 0V, VI/VO = 5.5V; prevents damaging backflow during hot-insertion or partial system power-down. |
| ESD Protection | HBM >2000V, CDM >1000V, MM >200V; meets IEC 61000-4-2 Level 2 for board-level robustness in consumer and industrial environments. |
Pinout & Package
SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65mm lead pitch) - ultra-compact 5-pin SC-70 package with exposed pad option; optimized for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Primary logic input; accepts 0V–5.5V regardless of VCC; internally clamped. |
| 2 (B) | Data Input | Secondary logic input; identical electrical behavior to Pin 1; both inputs fully 5.5V tolerant. |
| 3 (GND) | Ground Reference | Return path for all internal current; must be low-impedance connection to minimize noise coupling. |
| 4 (Y) | Data Output | Push-pull CMOS output; drives high/low actively; supports fan-out of ≥10 LVC loads at 3.3V. |
| 5 (VCC) | Power Supply | Core supply input; decoupling capacitor (100nF) required within 2mm for stable switching operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5V) | Enables drop-in replacement across 1.8V, 2.5V, 3.3V, and 5V logic subsystems without redesign. |
| 5.5V-tolerant inputs | Eliminates external level translators when interfacing with 5V microcontrollers or legacy peripherals. |
| IOFF partial-power-down | Prevents current backflow during VCC ramp-down or hot-swap events, protecting upstream drivers and downstream loads. |
| Low dynamic power (Cpd = 14pF) | Reduces switching current consumption in battery-powered devices; typical ICC < 0.1μA at standby. |
| Industrial temp support (−40°C to +125°C) | Validated for use in automotive infotainment head units, industrial HMIs, and outdoor-connected peripherals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | Same logic function and IOFF, but in SOT-23-5 (2.9mm × 1.6mm); 20% larger footprint than SOT353. | Less suitable for ultra-dense layouts where 2.0mm × 2.0mm area is constrained; otherwise identical timing and drive. | Select if existing design uses SOT-23 land pattern or requires higher thermal dissipation (θJA = 204°C/W vs. 371°C/W). |
| 74AUP1G86GW,125 | Lower static current (ICC = 0.9μA typ), wider VCC (0.8–3.6V), but no 5.5V input tolerance; max VCC = 3.6V. | Not usable in mixed 5V/3.3V systems; limited to single-supply sub-3.6V domains like wearables or BLE sensors. | Select only for ultra-low-power battery applications where 5V interface is absent and supply is strictly ≤3.6V. |
Compared with SN74LVC1G86DBVR and 74AUP1G86GW,125, the 74LVC1G86SE-7 uniquely balances ultra-small SOT353 size, full 5.5V input tolerance, and industrial temperature support-making it optimal for space-constrained, multi-voltage embedded interfaces requiring robust power-down behavior.

FAQ
Can the 74LVC1G86SE-7 operate with VCC = 1.65V while receiving 5.5V inputs?
Yes. The device guarantees full functionality at VCC = 1.65V with inputs up to 5.5V, enabled by its overvoltage-tolerant input structure. This allows direct connection to 5V sources (e.g., legacy microcontrollers) without external level shifters, provided output loading remains within ±24mA limits at that VCC.
What is the maximum capacitive load the 74LVC1G86SE-7 can drive at 3.3V while maintaining tPD ≤6.5ns?
The datasheet specifies tPD ≤6.5ns under CL = 50pF (including test fixture). With typical board trace capacitance (~2–5pF) and standard LVC fan-out (10 loads), it reliably drives ≤30pF total load. Exceeding 50pF increases tPD nonlinearly and may cause marginal timing in high-speed paths.
Does the IOFF feature require external pull-up/down resistors on inputs or outputs during power-down?
No. IOFF automatically disables the output buffer when VCC = 0V, presenting high-impedance state regardless of input voltage. Inputs remain clamped but do not require external biasing; however, unused inputs should be tied to VCC or GND per recommended operating conditions to prevent floating-induced shoot-through.
How does the SOT353 package of the 74LVC1G86SE-7 compare thermally to SOT25 for continuous operation at 24mA output current?
SOT353 has θJA = 371°C/W versus SOT25's 204°C/W. At 24mA sink/source and 3.3V VCC, power dissipation is ~80mW; junction rise is ~30°C in SOT25 but ~30°C × (371/204) ≈ 54°C in SOT353. Thus, SOT353 requires tighter thermal layout (e.g., 2oz copper, thermal vias) for sustained high-drive operation above 85°C ambient.
