CD74ACT283M96 Equivalent & Substitute Parts

Part Overview

The CD74ACT283M96 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, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates within a 4.5V to 5.5V supply voltage range and supports operating temperatures from -55°C to 125°C, typical for industrial and commercial applications requiring reliable arithmetic logic functions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74ACT283M96 is determined by the following critical parameters:

• Logic Function: Binary full adder with fast carry capability (4-bit)
• Bit Width: 4-bit configuration
• Supply Voltage Range: 4.5V to 5.5V compatibility
• Operating Temperature Range: -55°C to 125°C
• Package Type: 16-SOIC surface mount package with 0.154" width (3.90mm)
• Series Compatibility: 74ACT logic family

The substitute part CD74ACT283M must match all these parameters to ensure functional and mechanical compatibility within existing designs. Variations in any of these core parameters would require design-level evaluation and are not considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT283M manufactured by Harris Corporation is a direct functional equivalent to the CD74ACT283M96. Both parts share identical logic specifications, voltage ratings, temperature ranges, and package configurations. The primary distinction is the RoHS compliance status: the main part is ROHS3 compliant, while the substitute is RoHS non-compliant. This difference is significant for applications subject to RoHS regulations and must be evaluated against project requirements and regional compliance mandates. Both parts are classified as obsolete, indicating limited future availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT283M be used as a direct replacement for the CD74ACT283M96?

A: Yes, the CD74ACT283M is functionally equivalent. Both parts are 4-bit binary full adders with fast carry logic, operate at 4.5V to 5.5V, support -55°C to 125°C temperature ranges, and use identical 16-SOIC packaging. The substitute is suitable for applications where RoHS non-compliance is acceptable.

Q: What is the impact of the RoHS compliance difference?

A: The CD74ACT283M96 is ROHS3 compliant, while the CD74ACT283M is not. For applications or markets requiring RoHS compliance, the non-compliant substitute may not be acceptable. Verify compliance requirements before selection.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the 16-SOIC surface mount package with identical 0.154" (3.90mm) width specifications. PCB footprints and assembly processes are interchangeable.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these parts are no longer in active production. Availability is limited to existing inventory. For new designs, consider evaluating current-generation 4-bit adder alternatives within the 74ACT or compatible logic families.

Q: What are the key parameters that must match for substitution?

A: Logic function (4-bit binary full adder), bit width (4), supply voltage (4.5V–5.5V), operating temperature range (-55°C–125°C), package type (16-SOIC), and series family (74ACT) must all match for direct substitution.
