74F283PC Binary Full Adder Equivalent & Substitute Parts

Part Overview

The 74F283PC is a 4-bit binary full adder with fast carry logic manufactured by onsemi. This through-hole DIP package component performs parallel binary addition with carry propagation. The product status is obsolete, making equivalent substitutes necessary for ongoing design support, maintenance, and new production requirements where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F283PC is determined by strict equivalence across the following parameters:

• Logic Function: Binary full adder with fast carry (4-bit)
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V; operating temperature 0°C ~ 70°C
• Physical Package: 16-DIP (0.300", 7.62mm) through-hole configuration
• Pin Configuration: 16-PDIP supplier device package
• Base Product Series: 74F logic family

The SN74F283N from Texas Instruments meets all substitution criteria as a direct functional and pin-compatible equivalent within the 74F283 product family.

Parameter Comparison

Engineering Selection Recommendations

The SN74F283N is a direct substitute for the 74F283PC based on the following factors:

• Functional Equivalence: Both components implement identical 4-bit binary full adder logic with fast carry propagation
• Electrical Compatibility: Matching supply voltage range (4.5V ~ 5.5V) and operating temperature specifications (0°C ~ 70°C)
• Physical Compatibility: Identical 16-DIP through-hole package dimensions and pin configuration
• Regulatory Compliance: Both components share REACH Unaffected status and EAR99 ECCN classification
• Product Availability: The SN74F283N maintains active product status with current manufacturing support, addressing the obsolescence of the 74F283PC

Frequently Asked Questions (FAQ)

Q: Can the SN74F283N directly replace the 74F283PC in existing designs?

A: Yes. The SN74F283N is pin-compatible and functionally equivalent. Both components operate within identical electrical specifications and use the same 16-DIP through-hole package.

Q: What is the primary reason for substitution?

A: The 74F283PC is obsolete. The SN74F283N provides active manufacturing support and equivalent performance for the same 4-bit binary full adder function.

Q: Are there package differences between these parts?

A: No. Both the 74F283PC and SN74F283N use the 16-DIP (0.300", 7.62mm) through-hole package with identical pin assignments.

Q: Do these components have different compliance certifications?

A: Both components share REACH Unaffected status and EAR99 ECCN classification. The SN74F283N includes RoHS3 compliance, which is not specified for the 74F283PC.

Q: What are the critical parameters for substitution?

A: Supply voltage (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), 4-bit logic function, and 16-DIP package configuration must remain constant for substitution validity.
