74HCT2G86DP,125

Overview

The Nexperia 74HCT2G86DP,125 is a dual 2-input EXCLUSIVE-OR gate in the HCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input levels. The device features two independent XOR gates with inputs including clamp diodes for overvoltage tolerance. It is housed in an SOT505-2 (TSSOP8) package. Static characteristics specify low leakage current and defined output voltage levels under standard load conditions.

Feature Summary

• Dual 2-input EXCLUSIVE-OR logic function
• TTL-compatible input switching levels
• Input clamp diodes for overvoltage tolerance
• ESD protection exceeding JEDEC Class 2 and C3 standards

Applications

• Digital signal processing circuits
• Data transmission error detection systems
• Logic level translation between mixed-voltage domains

Selection Notes

Select this component when a compact dual XOR solution is required for 5 V digital logic applications. The HCT series ensures compatibility with standard TTL outputs while maintaining CMOS power efficiency. Ensure the design accommodates the specified propagation delay limits at the target operating voltage and temperature range.

Part Context

This part belongs to the Nexperia 74HCT2Gxx family of single-function logic gates. These devices are designed for high-speed operation in small outline packages. The 74HCT2G86 specifically provides exclusive-OR functionality, distinguishing it from other gates like NAND or OR variants within the same package footprint.

Replacement Considerations

Direct pin-compatible replacements include the 74HC2G86DP variant, which offers CMOS input levels instead of TTL. Other dual XOR gates in similar packages may require verification of input/output voltage thresholds and propagation delays to ensure functional equivalence.
