Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74ACT283M96G4 is determined by strict equivalence across the following critical parameters:

• Logic Function: Binary full adder with fast carry (4-bit)
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V; operating temperature -55°C ~ 125°C
• Package Compatibility: 16-SOIC surface mount package with 0.154" (3.90mm) width
• Series Compatibility: 74ACT logic family
• Pin Configuration: Identical pinout and signal definitions

The CD74ACT283M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in manufacturer origin and RoHS compliance status do not affect functional interchangeability within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT283M from Harris Corporation is a functional equivalent to the CD74ACT283M96G4. Both parts share identical electrical specifications, package geometry, and logic functionality. Selection between these parts should be based on the following considerations:

RoHS Compliance Requirements: The main part (CD74ACT283M96G4) carries ROHS3 compliance certification, while the substitute (CD74ACT283M) is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the Texas Instruments variant.

Product Status: Both parts are classified as obsolete. Procurement planning should account for limited availability and potential supply discontinuation.

Manufacturer Availability: The Harris Corporation variant shows higher current inventory (4181 pcs) compared to the Texas Instruments version (743 pcs), which may influence lead time and cost considerations for high-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT283M be used as a direct replacement for the CD74ACT283M96G4?

A: Yes, the CD74ACT283M is functionally equivalent. Both parts operate at identical supply voltages (4.5V ~ 5.5V), support the same temperature range (-55°C ~ 125°C), and use the 16-SOIC package. Pin configuration and logic behavior are identical.

Q: What is the difference in RoHS compliance between these parts?

A: The CD74ACT283M96G4 (Texas Instruments) is ROHS3 compliant, while the CD74ACT283M (Harris Corporation) is RoHS non-compliant. Applications requiring RoHS certification must specify the Texas Instruments part.

Q: Are there any package or mounting differences?

A: No. Both parts use the 16-SOIC surface mount package with identical dimensions (0.154" or 3.90mm width). 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 by their manufacturers. This classification affects long-term availability and may influence procurement strategy for designs requiring extended product lifecycles.

Q: Which part should be selected for new designs?

A: For new designs, evaluate current market availability and RoHS compliance requirements. The Texas Instruments variant (CD74ACT283M96G4) is preferred for RoHS-regulated applications. For applications without RoHS constraints, either part is functionally suitable based on availability and cost.
