Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC280D,653 is determined by the following critical parameters:

• Logic Function: Parity Generator/Checker with 9-bit configuration
• Package Compatibility: 14-SOIC form factor with 0.154" width (3.90mm)
• Electrical Performance: Supply voltage range 2 V ~ 6 V
• Compliance Requirements: RoHS3 compliance and MSL Level 1 rating
• Series Compatibility: 74HC logic family

The substitute parts CD74HC280M96 and CD74HC280MT meet all substitution criteria through identical functional specification, package geometry, and regulatory compliance. Both are manufactured by Texas Instruments within the same 74HC series.

Parameter Comparison

Engineering Selection Recommendations

CD74HC280M96 is the primary substitute for the 74HC280D,653. Both components maintain active production status, ensuring long-term availability and supply chain stability. This part carries identical electrical and mechanical specifications with documented output current ratings of 5.2mA for both high and low states.

CD74HC280MT provides functional equivalence with identical electrical and mechanical parameters. However, this part carries a Last Time Buy status, indicating discontinued production with limited remaining inventory (1015 units). Selection of this substitute should be limited to applications where existing stock allocation is available and long-term supply is not a design requirement.

Both substitutes maintain full RoHS3 compliance, MSL Level 1 rating, and compatibility with the 14-SOIC package footprint. Selection between active and Last Time Buy alternatives depends on project timeline and inventory planning requirements.

Frequently Asked Questions (FAQ)

Q: Can CD74HC280M96 and CD74HC280MT be used interchangeably with 74HC280D,653?

A: Yes. Both Texas Instruments parts are functionally equivalent substitutes. They share identical logic function (9-bit parity generator/checker), package geometry (14-SOIC), supply voltage range (2 V ~ 6 V), and regulatory compliance (RoHS3, MSL Level 1). The primary difference is product status: CD74HC280M96 is in active production, while CD74HC280MT is Last Time Buy.

Q: What is the significance of the Last Time Buy status for CD74HC280MT?

A: Last Time Buy indicates the manufacturer has discontinued production. Current inventory is limited to 1015 units. This part should only be selected if existing stock is allocated to the project or if short-term supply is sufficient. For new designs or long-term production, CD74HC280M96 is the recommended choice.

Q: Are there any differences in output current specifications between the main part and substitutes?

A: The 74HC280D,653 datasheet does not specify output current values. The Texas Instruments substitutes (CD74HC280M96 and CD74HC280MT) document output current at 5.2mA for both high and low states. This additional specification does not affect substitution eligibility but provides enhanced design margin documentation.

Q: Do all three parts use the same 14-SOIC package footprint?

A: Yes. All three parts use the 14-SOIC package with 0.154" width (3.90mm). PCB footprints and reflow profiles are identical, allowing direct substitution without layout modifications.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts maintain identical RoHS3 compliance, MSL Level 1 rating, REACH unaffected status, and ECCN/HTSUS classifications. Regulatory and environmental compliance is equivalent across all options.
