Substitute Part Grouping Explanation

Substitute parts for the CD74ACT08M96 are qualified based on the following criteria:

Base product number equivalence (74ACT08 family)
Identical logic configuration (4-channel, 2-input AND gate)
Matching electrical specifications (supply voltage, input/output levels, quiescent current, output drive capability)
Compatible package type (14-SOIC surface mount)
Active product status with current manufacturing support
Compliance with RoHS3 and REACH requirements

The substitute parts identified—74ACT08SCX, 74ACT08SC, MC74ACT08DG, and MC74ACT08DR2G—all meet these criteria. Variations in packaging format (Cut Tape & Digi-Reel, Tube, or Tape & Reel) do not affect electrical compatibility and represent different distribution methods for the same functional device.

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and functional equivalence to the CD74ACT08M96. Selection among the substitute options should be based on the following factors:

Operating Temperature Range: The CD74ACT08M96 supports -55°C to 125°C operation, while all onsemi substitutes support -40°C to 85°C. Applications requiring extended low-temperature operation below -40°C must retain the Texas Instruments part.

Propagation Delay: The onsemi substitutes (74ACT08SCX, 74ACT08SC, MC74ACT08DG, MC74ACT08DR2G) offer improved propagation delay of 9ns compared to the CD74ACT08M96 at 12.9ns. This faster switching characteristic is compatible with all applications designed for the original part.

Packaging Format: All substitutes are available in 14-SOIC surface mount packaging. Selection between Cut Tape & Digi-Reel (74ACT08SCX), Tube (74ACT08SC, MC74ACT08DG), or Tape & Reel (MC74ACT08DR2G) depends on assembly process requirements and order quantities.

Compliance: All parts maintain ROHS3 compliance and REACH unaffected status, suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the onsemi 74ACT08SCX replace the Texas Instruments CD74ACT08M96 in existing designs?

A: Yes, the 74ACT08SCX is electrically equivalent for all standard operating conditions within the overlapping temperature range (-40°C to 85°C). The improved propagation delay of 9ns versus 12.9ns is a performance enhancement that does not create compatibility issues. Designs operating above 85°C or below -40°C require the original CD74ACT08M96.

Q: What is the difference between 74ACT08SCX, 74ACT08SC, MC74ACT08DG, and MC74ACT08DR2G?

A: These parts are functionally identical 4-channel 2-input AND gates with the same electrical specifications. The differences are in packaging format: 74ACT08SCX uses Cut Tape & Digi-Reel distribution, 74ACT08SC and MC74ACT08DG use Tube packaging, and MC74ACT08DR2G uses Tape & Reel. Selection depends on assembly process and order quantity requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all identified substitute parts—74ACT08SCX, 74ACT08SC, MC74ACT08DG, and MC74ACT08DR2G—are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the compliance profile of the CD74ACT08M96.

Q: What is the impact of the faster propagation delay in onsemi substitutes?

A: The onsemi substitutes feature 9ns propagation delay compared to 12.9ns in the CD74ACT08M96. This faster switching is a performance improvement that maintains backward compatibility. No circuit redesign is required, and timing margins are improved.

Q: Can I mix manufacturers in the same circuit board?

A: Yes, all parts operate within identical electrical specifications for supply voltage, input/output levels, and quiescent current. Mixing Texas Instruments and onsemi parts on the same board is electrically compatible within the overlapping operating temperature range.
