Key Features
- Dual 2-input XOR gate in LVC CMOS operating from 1.65V to 5.5V for wide mixed-voltage system compatibility
- Fast propagation delay as low as 3.8ns at 3.3V enabling high-speed parity checking and digital comparison circuits
- Ultra-compact 8-pin VSSOP footprint (~3mm²) for area-sensitive logic integration in portable and wearable electronics
Applications
The SN74LVC2G86DCU3 is used in digital parity-check circuits, data encryption/decryption logic, and phase-comparison circuits across consumer electronics, communications equipment, and industrial controllers. Its wide 1.65V to 5.5V supply range and tiny VSSOP-8 package make it an ideal glue-logic building block in mixed-voltage designs where XOR functions are needed alongside microcontrollers or FPGAs operating at different logic levels.

Frequently Asked Questions
What supply voltage range does SN74LVC2G86DCU3 support and how does it handle mixed-voltage interfaces?
The SN74LVC2G86DCU3 operates from 1.65V to 5.5V, allowing it to work directly with 1.8V, 2.5V, 3.3V, and 5V logic systems. Its 5V-tolerant inputs also accept signals above the supply rail without damage, making it straightforward to use as an XOR gate between a 3.3V microcontroller and a 5V legacy peripheral without external level shifting.
How fast is signal propagation through SN74LVC2G86DCU3 at typical operating voltages?
At a 3.3V supply, the device achieves a typical propagation delay of approximately 3.8ns and a maximum of 6.5ns. At 5V, delays are even lower, enabling clock frequencies well above 100MHz for XOR-based serial data processing, CRC generation, or pseudorandom number generation in embedded systems.
What common logic functions can be built using the two XOR gates in SN74LVC2G86DCU3?
With 2 independent 2-input XOR gates, the device supports single-bit parity generation and checking, 1-bit full-adder sum outputs, programmable inverter/buffer functions (by tying one input to VCC or GND), and phase-difference detection for lock-detect circuits. These 4 distinct logic functions are achievable with a single 8-pin IC.
How does the VSSOP-8 package footprint compare to older logic packages for board-space savings?
The VSSOP-8 package occupies a PCB footprint of approximately 3.0mm x 3.0mm, which is roughly 70% smaller than a standard SOIC-8 package that would occupy about 5.0mm x 6.2mm. This significant area reduction is valuable in wearables, hearing aids, and densely populated IoT PCBs where dual-gate logic functions must fit alongside other surface-mount components.
