74HC86D

Overview

The Toshiba Semiconductor and Storage 74HC86D is a high-speed CMOS Quad Exclusive OR Gate fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 to 6.0 V and supports an operating temperature from -40°C to 125°C. The device features balanced propagation delays, achieving typical speeds of 10 ns at 5 V. Quiescent current is limited to 1.0 µA maximum at 25°C. Output drive capability reaches ±5.2 mA. It is housed in a 14-pin SOIC package.

Feature Summary

• High-speed operation comparable to equivalent LSTTL while maintaining low power dissipation
• Input and output buffers provide high noise immunity and stable output performance
• All inputs are equipped with protection circuits against static discharge or transient excess voltage

Applications

• Digital logic circuits requiring exclusive OR functionality
• Data processing systems utilizing XOR operations
• General-purpose digital signal routing applications

Procurement Notes

Verify the manufacturer designation as Toshiba Semiconductor and Storage for the specific 74HC86D part number. Confirm the package type matches the required 14-SOIC form factor. Ensure the operating environment falls within the specified -40°C to 125°C temperature range. Validate that the supply voltage requirements align with the 2.0 V to 6.0 V operational limits defined in the datasheet.

Selection Notes

Select this component when a quad XOR gate is required in a surface-mount design. The 74HC series ensures compatibility with standard logic families. Consider the 14-SOIC package dimensions for PCB layout constraints. Evaluate the 5.2 mA output drive strength against load requirements. Verify input protection needs for environments prone to electrostatic discharge.

Part Context

The 74HC86D belongs to the 74HC family of high-speed CMOS logic devices. This series is designed to be pin-compatible with older Low-power Schottky TTL (LSTTL) standards. The device implements four independent two-input XOR gates on a single monolithic silicon chip. It represents a modern CMOS implementation of classic logic functions.

Replacement Considerations

Cross-reference with other manufacturers' 74HC86 equivalents such as SN74HC86 or NXP variants. Verify pinout compatibility and electrical characteristics match before substitution.
