74AC86SCX_SF86755A

Overview

The onsemi 74AC86SCX is a Quad 2-Input Exclusive-OR Gate from the AC logic series, 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 range of -40 °C to +85 °C. The device features outputs capable of sourcing or sinking 24 mA. Propagation delay is typically 6.5 ns at 3.3 V and 4.5 ns at 5.0 V under a 50 pF load.

Feature Summary

• Contains four independent 2-input exclusive-OR gates for complex logic implementation
• Provides high drive capability with output currents reaching 24 mA
• Features significantly reduced quiescent supply current compared to previous generations

Applications

• Digital logic circuits requiring XOR functionality
• Parity generators and checkers
• Arithmetic logic units (ALUs)
• Error detection systems

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm RoHS compliance status as indicated by the marking code. Ensure the procurement channel provides valid traceability documentation. Check for any specific handling requirements related to electrostatic discharge protection during storage and assembly processes.

Selection Notes

Select this component when a quad XOR gate configuration is required within standard AC logic families. Consider the 24 mA output drive strength for direct load interfacing needs. Evaluate the propagation delay specifications against system timing constraints. Verify that the SOIC-14 package dimensions fit the available PCB real estate.

Part Context

This part belongs to the 74AC logic family, known for high-speed operation and low power consumption. It serves as a digital logic building block for implementing Boolean functions. The AC series offers improved performance over older HC or HCT variants while maintaining compatibility with standard logic levels.

Replacement Considerations

Compatible substitutes include other manufacturers' 74AC86 devices in SOIC-14 packages. Cross-reference pinouts and electrical characteristics to ensure functional equivalence. Verify that alternative parts meet the same voltage and temperature operating ranges.
