74HC2G86GD,125

Overview

The Nexperia 74HC2G86GD,125 is a dual two-input exclusive-OR gate implemented in high-speed silicon-gate CMOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V and features overvoltage-tolerant inputs. The device provides symmetrical output impedance and balanced propagation delays, ensuring reliable performance across a wide temperature range from -40°C to +125°C. Packaged in an 8-DFN surface-mount format, it offers low power dissipation and high noise immunity suitable for mixed-voltage applications.

Feature Summary

• Dual exclusive-OR logic function with two independent channels
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Symmetrical output impedance with balanced propagation delays

Applications

• Mixed voltage level translation between different logic families
• Parity generation and error detection circuits
• Arithmetic logic operations such as addition and subtraction

Procurement Notes

Verify the specific suffix GD against the official Nexperia datasheet to confirm the 8-DFN package configuration. Ensure compatibility with RoHS3 and REACH regulations by checking the latest product change notifications. Confirm that the operating voltage requirements align with the 2.0 V to 6.0 V specification before integration into the design.

Selection Notes

Select this component when a compact dual XOR solution is required for space-constrained designs. The 74HC series is appropriate for applications needing standard CMOS input levels and moderate speed. Consider the 8-DFN package for its small footprint compared to traditional TSSOP options while maintaining robust thermal and electrical performance.

Part Context

This part belongs to the Nexperia 74HC family of single-function gates, designed for general-purpose digital applications. The 74HC2G86 specifically provides two XOR gates in a minimal package, serving as a fundamental building block for complex logic circuits. It complements other 74HC devices like NAND and OR gates within the same series for system consistency.

Replacement Considerations

Check for direct pin-compatible alternatives within the 74HC2G86 series from Nexperia or other manufacturers. Verify that any substitute maintains the same 8-DFN package dimensions and electrical characteristics, particularly the supply voltage range and propagation delay specifications.
