MC74F521N

Comparators Overview

The MC74F521N is an 8-bit identity comparator belonging to the 74F series. It features inverted active-low outputs that indicate equality between two 8-bit inputs. The device operates within a standard temperature range and provides defined output current capabilities for high and low states.

Comparators Feature Summary

• Performs 8-bit identity comparison with inverted logic
• Generates active-low output signal when input values are equal
• Compatible with TTL logic families

Comparators Applications

• Digital system data validation
• Address matching circuits
• Comparator logic in industrial control systems

Comparators Procurement Notes

Verify the package type corresponds to PDIP-20 as indicated by the 'N' suffix. Confirm the product status is Active. Ensure compliance with RoHS standards if required for the specific application environment.

Comparators Selection Notes

Select this component for applications requiring fast 8-bit equality checking. Consider the active-low output polarity and TTL compatibility. Evaluate the through-hole mounting requirement against available board space and assembly methods.

Comparators Part Context

This part belongs to the 74F (Fast) logic family, known for higher speed performance compared to standard variants. It serves as a fundamental digital building block for comparing binary data streams in legacy and mixed-signal designs.

Comparators Replacement Considerations

Check for equivalent parts from other manufacturers offering the same 74F series specifications and PDIP-20 package. Verify pinout compatibility before substitution.
