N74F85D,512

Comparators Overview

The N74F85D,512 is a 4-bit magnitude comparator manufactured by NXP USA Inc. It features active high outputs for A<B, A=B, and A>B comparisons. The device operates within a voltage range of 4.5V to 5.5V and supports a maximum propagation delay of 14ns at 5V with 50pF load. It utilizes a 16-SOIC package and functions within an operating temperature range of 0°C to 70°C.

Comparators Feature Summary

• Performs 4-bit magnitude comparison between two binary words
• Provides active high logic outputs for less than, equal, and greater than conditions
• Supports cascading capabilities for expanding bit-width comparisons

Comparators Applications

• Digital arithmetic logic units
• Address decoding circuits
• Data sorting systems

Comparators Procurement Notes

Verify the specific suffix '512' against official NXP documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as product availability may vary. Ensure the 16-SOIC footprint matches the target PCB design requirements before finalizing procurement orders.

Comparators Selection Notes

Select this component when a standard TTL-compatible magnitude comparator is required for 4-bit data paths. Consider the 14ns propagation delay for timing constraints in the application circuit. Verify that the 4.5V to 5.5V supply voltage aligns with the system power rails.

Comparators Part Context

This part belongs to the 74F series of high-speed CMOS logic devices. It serves as a functional equivalent to other industry-standard 4-bit comparators. The device is designed for general-purpose digital logic applications requiring reliable magnitude comparison operations.

Comparators Replacement Considerations

Check for direct pin-to-pin replacements from other manufacturers offering 74F85 equivalents. Verify electrical parameter compatibility, specifically output drive strength and propagation delay, before substituting.
