CD74ACT04M96E4 Equivalent & Substitute Parts

Part Overview

The CD74ACT04M96E4 is a 6-channel inverter logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part operates within the 74ACT logic family and is classified as obsolete.

Substitute Part Grouping Explanation

Substitution for the CD74ACT04M96E4 is determined by strict equivalence across the following parameters:

Logic type (Inverter)
Number of circuits (6 channels)
Number of inputs (1 per channel)
Supply voltage range (4.5V ~ 5.5V)
Output current capability (24mA high and low)
Input logic thresholds (0.8V low, 2V high)
Package type (14-SOIC)
Mounting type (Surface Mount)
Base product number (74ACT04)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in propagation delay, operating temperature range, product status, and compliance certifications are noted but do not disqualify substitution eligibility based on functional equivalence.

Engineering Selection Recommendations

For applications currently using the CD74ACT04M96E4, the following selection criteria apply:

Active Product Status Priority: MC74ACT04DR2G, 74ACT04SC, and 74ACT04SCX are all active products from onsemi and represent the preferred substitutes for long-term availability and supply chain continuity.

RoHS Compliance: All active substitutes (MC74ACT04DR2G, 74ACT04SC, 74ACT04SCX) maintain ROHS3 compliance, matching the original part's compliance status. CD74ACT04M96 from Harris Corporation is non-compliant and should be avoided in applications requiring RoHS certification.

Operating Temperature Consideration: The original CD74ACT04M96E4 operates across -55°C ~ 125°C. Active substitutes operate within -40°C ~ 85°C. Applications requiring the extended lower temperature range (-55°C) must retain the original part or CD74ACT04M96 from Harris Corporation.

Propagation Delay: Active onsemi substitutes (MC74ACT04DR2G, 74ACT04SC, 74ACT04SCX) offer improved propagation delay of 8.5ns compared to the original 9.3ns, providing performance margin without functional impact.

Packaging Format: Selection between MC74ACT04DR2G (Tape & Reel), 74ACT04SC (Tube), and 74ACT04SCX (Cut Tape & Digi-Reel) depends on procurement volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CD74ACT04M96E4 with any of the listed parts?

A: All listed parts are functionally equivalent based on logic type, circuit count, input configuration, supply voltage, output current, input thresholds, and package type. However, operating temperature range and product status must be evaluated for your specific application requirements.

Q: What is the difference between the onsemi substitutes (MC74ACT04DR2G, 74ACT04SC, 74ACT04SCX)?

A: All three onsemi parts are electrically identical. The differences are in packaging format: MC74ACT04DR2G is supplied in Tape & Reel, 74ACT04SC in Tube, and 74ACT04SCX in Cut Tape & Digi-Reel. Selection depends on your assembly process and order quantity.

Q: Why is the CD74ACT04M96 from Harris Corporation listed if it is non-compliant?

A: CD74ACT04M96 maintains full electrical equivalence and is included for reference in legacy system documentation. However, it does not meet ROHS3 compliance and should not be selected for new designs or applications requiring RoHS certification.

Q: Does the improved propagation delay of active substitutes affect circuit operation?

A: The active onsemi substitutes provide 8.5ns propagation delay compared to the original 9.3ns. This represents faster switching performance and does not create compatibility issues. Circuits designed for the original part will function correctly with the faster substitute.

Q: What should I do if my application requires the -55°C lower operating temperature?

A: If your design requires operation below -40°C, the original CD74ACT04M96E4 or CD74ACT04M96 must be retained, as active substitutes are limited to -40°C ~ 85°C. Verify long-term availability through your supplier before committing to this requirement.

Q: Are all substitute parts pin-compatible with the original?

A: Yes. All parts use the 14-SOIC package with identical pinout and are direct mechanical and electrical replacements.
