Substitute Part Grouping Explanation

Substitution of the CD74HCT670M96 is determined by strict equivalence across the following critical parameters:

• Functional Type: Register File with identical circuit configuration (1 × 1:1)
• Independent Circuits: 4 circuits required
• Voltage Supply: Single supply operation at 4.5V ~ 5.5V
• Operating Temperature Range: -55°C ~ 125°C
• Package / Case: 16-SOIC surface mount package (0.154", 3.90mm Width)
• Series Compatibility: 74HCT logic family
• Compliance: ROHS3 compliant, MSL 1, REACH unaffected

The CD74HCT670M differs from the main part only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard packaging). All electrical and mechanical parameters remain identical, establishing direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The CD74HCT670M is the direct substitute for the CD74HCT670M96. Both parts share identical electrical specifications, circuit configuration, and mechanical packaging. The primary distinction is product status: CD74HCT670M is classified as Active, while CD74HCT670M96 is Obsolete.

Selection of CD74HCT670M is supported by:

• Active product status ensuring continued manufacturer support and availability
• Full compliance with ROHS3 and REACH requirements
• Identical voltage supply range (4.5V ~ 5.5V) and operating temperature specifications (-55°C ~ 125°C)
• Matching 16-SOIC package geometry and pinout
• MSL 1 rating indicating no moisture sensitivity constraints

No design modifications or circuit adjustments are required when substituting CD74HCT670M for CD74HCT670M96.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT670M directly replace CD74HCT670M96 without design changes?

A: Yes. Both parts are electrically and mechanically identical. No circuit modifications, pin reassignments, or layout adjustments are necessary. The substitute operates within the same voltage supply range (4.5V ~ 5.5V) and temperature specifications (-55°C ~ 125°C).

Q: What is the difference between CD74HCT670M96 and CD74HCT670M?

A: The primary differences are product status (Obsolete vs. Active) and packaging format (standard vs. Tube). All functional and electrical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. Regulatory and environmental certifications are equivalent.

Q: Is the 16-SOIC package identical between both parts?

A: Yes. Both parts use the 16-SOIC package with 0.154" width (3.90mm). Pinout, pad layout, and mechanical dimensions are identical, ensuring direct PCB compatibility.

Q: Why is CD74HCT670M96 marked as Obsolete?

A: Product status reflects Texas Instruments' lifecycle classification. CD74HCT670M (Active status) is the current production equivalent and recommended for new designs and ongoing procurement.
