74AC86SCX_SF501651

Overview

The onsemi 74AC86SCX is a quad 2-input exclusive-OR gate in the 74AC logic family, housed in a 14-pin SOIC package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature from -40°C to +85°C. The device provides output source/sink currents of 24 mA and features reduced quiescent current (ICC). Propagation delays are specified at 9.5 ns maximum at 5.0 V and 12.5 ns maximum at 3.3 V under standard capacitive loading conditions.

Feature Summary

• Contains four independent 2-input exclusive-OR gates for complex logic operations
• Outputs capable of sourcing and sinking 24 mA drive current
• Reduced quiescent supply current compared to previous generations
• Compliant with RoHS standards and manufactured without halogen

Applications

• Digital signal processing circuits requiring XOR functionality
• Parity checkers and error detection systems
• Binary adder implementations
• Logic level translation between different voltage domains

Procurement Notes

Verify that the ordering suffix matches SCX for the SOIC-14 tape and reel configuration. Confirm the datasheet revision aligns with manufacturing requirements. Ensure compliance with specific environmental directives if applicable to the target market. Validate pinout compatibility during integration planning.

Selection Notes

Select this component when high-speed switching is required alongside moderate drive capability. The AC series offers faster performance than HC variants while maintaining CMOS power efficiency. Verify that the 2V to 6V supply range accommodates the system's voltage rails. Consider the 14-SOIC footprint constraints against available board space.

Part Context

This part belongs to the 74AC logic family, designed for high-speed applications using silicon-gate CMOS technology. It serves as a direct functional replacement for older TTL-based XOR gates but requires appropriate voltage level shifting. The device is widely used in general-purpose digital logic designs where speed and low power consumption are prioritized.

Replacement Considerations

Direct substitutes include MC74AC86DG and 74AC86MTCX from onsemi. Cross-manufacturer equivalents such as CD74AC86M from Texas Instruments offer compatible logic functions and pinouts.
