CD74ACT283M96E4 Equivalent & Substitute Parts

Part Overview

The CD74ACT283M96E4 is a 4-bit binary full adder with fast carry logic manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as obsolete, indicating it is no longer in active production. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for system redesign, legacy product support, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74ACT283M96E4 is determined by the following critical parameters:

• Logic Function: Binary full adder with fast carry operation (4-bit configuration)
• Electrical Specifications: Supply voltage range of 4.5V to 5.5V and operating temperature range of -55°C to 125°C
• Package Compatibility: 16-SOIC surface mount package with 0.154" width (3.90mm)
• Base Product Number: 74ACT283 series designation

Substitute parts must maintain identical electrical performance characteristics and physical package dimensions to ensure direct replacement capability without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT283M manufactured by Harris Corporation is a direct functional equivalent to the CD74ACT283M96E4. Both components share identical electrical specifications, package geometry, and logic functionality. Selection between these parts should be based on:

• Availability: Verify current inventory status with component suppliers, as both parts are obsolete
• RoHS Compliance Requirements: The Texas Instruments variant (CD74ACT283M96E4) is ROHS3 compliant, while the Harris Corporation variant (CD74ACT283M) is RoHS non-compliant. Design specifications must account for this compliance difference
• Procurement Lead Time: Obsolete components may have extended procurement cycles; confirm supplier delivery schedules

Both parts are suitable for applications requiring 4-bit binary addition with fast carry propagation in the 4.5V to 5.5V supply voltage range and -55°C to 125°C operating environment.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT283M from Harris Corporation directly replace the CD74ACT283M96E4 from Texas Instruments?

A: Yes. Both components are functionally equivalent 4-bit binary full adders with identical electrical specifications (4.5V–5.5V supply, -55°C to 125°C operating range) and package geometry (16-SOIC). Direct pin-for-pin replacement is possible without circuit modification.

Q: What is the significance of the "96E4" suffix in the Texas Instruments part number?

A: The "96E4" suffix is a Texas Instruments manufacturing code designating a specific production batch, date code, or packaging variant. The base product number 74ACT283 defines the functional specification; the suffix does not alter electrical or mechanical characteristics relevant to substitution.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The CD74ACT283M96E4 (Texas Instruments) is ROHS3 compliant, while the CD74ACT283M (Harris Corporation) is RoHS non-compliant. Applications subject to RoHS regulations must use the Texas Instruments variant or identify alternative modern components.

Q: Why are both parts listed as obsolete?

A: Both the 74ACT283 series components from Texas Instruments and Harris Corporation are no longer manufactured. Modern designs should evaluate contemporary 4-bit adder alternatives; however, these parts remain available through component distributors for legacy system support and repair applications.

Q: Does package width affect substitution eligibility?

A: No. Both parts use the identical 16-SOIC package with 0.154" (3.90mm) width. Package dimensions are fully compatible for PCB layout and assembly processes.
