HEF4585BP,652

Comparators Overview

The HEF4585BP,652 is a 4-bit magnitude comparator manufactured by NXP USA Inc. It compares two 4-bit binary words to determine if one is less than, equal to, or greater than the other. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a 16-pin DIP package with a 0.300-inch (7.62mm) width. It belongs to the 4000B series of CMOS logic devices.

Comparators Feature Summary

• Performs magnitude comparison between two 4-bit binary inputs
• Provides true output signals for less-than, equal-to, and greater-than conditions
• Compatible with standard 4000B series CMOS logic families

Comparators Applications

• Digital arithmetic logic units requiring magnitude evaluation
• Control systems comparing setpoints against measured values
• Data routing circuits based on numerical input comparisons

Comparators Procurement Notes

Verify the component status as obsolete when sourcing this part. Confirm the package type is 16-DIP and the operating temperature range meets system requirements. Ensure compatibility with existing 4000B series logic designs. Check for authorized distributors offering remaining stock or qualified replacement alternatives.

Comparators Selection Notes

Select this component for applications requiring simple 4-bit magnitude comparison without complex programming. It is suitable for general-purpose digital logic where CMOS power consumption is a consideration. Verify that the 16-pin DIP form factor fits the target PCB layout and mounting constraints.

Comparators Part Context

This comparator is part of the NXP 4000B series, which defines standard CMOS logic functions. The HEF4585B variant specifically handles 4-bit word comparisons. It serves as a foundational building block for digital decision-making circuits in industrial and consumer electronics.

Comparators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, verify functional equivalents from other manufacturers that match the 4-bit magnitude comparator specification and 16-DIP package.
