Product details
Overview
74LVC1G86FW5-7 from Diodes Incorporated is a single 2-input XOR gate in X1-DFN1010-6 (Type B) 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 logic interfaces.
For engineers reviewing the 74LVC1G86FW5-7 datasheet, 74LVC1G86FW5-7 pinout, 74LVC1G86FW5-7 application, or 74LVC1G86FW5-7 equivalent, key selection criteria include supply voltage range, IOFF-enabled power-down behavior, input voltage tolerance, propagation delay (≤6.5ns at 3.3V), and DFN package thermal resistance (θJA = 435°C/W).
Technical Context
This device implements a positive-logic exclusive OR function (Y = A·B̅ + Ā·B) using CMOS technology, supporting mixed-voltage interfacing via 5.5V-tolerant inputs while powered from as low as 1.65V. Its IOFF circuit disables output leakage during partial power-down, preventing backflow current when VCC = 0V.
Switching performance is characterized across 1.8V–5.0V supplies, with tPD ranging from 0.5ns (min) to 6.5ns (max) at 3.3V over –40°C to +125°C. Input transition rate is specified up to 20 ns/V at 1.8V, ensuring robust timing margin in high-speed digital systems.

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 1.65–5.5V range; uses SOT-23-5 (5-pin) package with no NC pin; θJA = 204°C/W | Larger footprint and higher thermal performance; lacks NC pin but requires different PCB layout | Select when board space permits larger package and lower junction-to-ambient resistance is prioritized over miniaturization |
| 74LVC1G86Z-7 | Identical logic and specs; packaged in 1.6mm × 1.6mm SOT553 with 0.5mm pitch; θJA = 231°C/W | More accessible hand-soldering and test probing than DFN; slightly larger area but better manufacturability | Choose for prototyping, low-volume production, or where DFN rework capability is limited |
Compared with SN74LVC1G86DBVR and 74LVC1G86Z-7, the 74LVC1G86FW5-7 offers the smallest PCB footprint (1.0mm²) and highest integration density, making it optimal for space-critical mobile and wearables designs-though its DFN package demands precision placement and reflow control.

FAQ
What is the maximum allowable input voltage when VCC = 0V?
The 74LVC1G86FW5-7 supports 5.5V-tolerant inputs regardless of VCC state. When VCC = 0V, the IOFF circuit disables the output, and inputs may safely remain at up to 5.5V without causing back-current or damage-verified per JESD78 latch-up testing (>100mA) and absolute maximum ratings.
Can this device drive a 50pF load at 10MHz without signal degradation?
Yes. With Cpd = 14pF and typical output drive of ±24mA at 3.3V, the device can reliably drive a 50pF capacitive load at 10MHz. Propagation delay remains ≤6.5ns, and output voltage swing stays within VOL ≤0.55V and VOH ≥2.0V under those conditions per datasheet switching characteristics.
Is the NC pin on the X1-DFN1010-6 (Type B) package required to be grounded or left floating?
The NC pin must remain unconnected and un-soldered-neither grounded nor tied to any net. Per Diodes Incorporated's datasheet (page 2, Pin Assignments), it is an unbonded terminal; connecting it risks internal shorting or undefined behavior due to die-level construction.
Does this part support hot-plug operation in systems with asynchronous power sequencing?
Yes. The IOFF feature ensures that when VCC is ramping or zero, the output enters high-impedance state and input pins remain tolerant to 5.5V. This enables safe hot-plug operation in multi-rail systems-confirmed by ESD ratings (2kV HBM) and partial-power-down characterization across –40°C to +125°C.
