CD74AC04M Equivalent & Substitute Parts

Part Overview

The CD74AC04M is a 6-channel inverter logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The CD74AC04M operates across a supply voltage range of 1.5V to 5.5V with a maximum propagation delay of 6.5ns at 5V with 50pF load. Substitute parts must maintain functional equivalence in inverter logic operation while meeting the same package and pin configuration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74AC04M are qualified based on the following criteria:

Functional Equivalence: All substitute parts maintain the same logic type (inverter), circuit count (6 channels), and input configuration (1 input per channel).

Package Compatibility: All substitutes use the 14-SOIC package with identical 0.154" (3.90mm) width, ensuring direct pin-for-pin compatibility and PCB layout interchangeability.

Electrical Performance: Substitute parts operate within compatible voltage supply ranges and maintain output drive capability (24mA high and low) and input logic level thresholds suitable for standard TTL/CMOS interfacing.

Compliance Standards: All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Series Designation: All parts belong to the 74AC logic family, confirming functional and electrical compatibility within this established standard.

Engineering Selection Recommendations

CD74AC04M96 (Texas Instruments): This part is the direct Texas Instruments equivalent with active product status. It maintains identical electrical specifications to the obsolete CD74AC04M, including the 1.5V to 5.5V supply voltage range and 6.5ns propagation delay. This part is preferred for applications requiring the original Texas Instruments manufacturing source and extended temperature range (-55°C to 125°C). Available in Cut Tape and Digi-Reel packaging with 2570 units in stock.

74AC04SC, 74AC04SCX, MC74AC04DG, MC74AC04DR2G (onsemi): These onsemi-manufactured parts provide functional substitution with active product status and ROHS3 compliance. The onsemi variants operate within a 2V to 6V supply voltage range, which encompasses standard 5V logic applications. Propagation delay is 7ns at 5V with 50pF load, representing a 0.5ns increase from the original specification. Operating temperature range is -40°C to 85°C, suitable for commercial and industrial applications. These parts are available in multiple packaging options (Tube and Cut Tape/Digi-Reel) with substantial inventory availability (47,750 units for 74AC04SCX and 55,500 units for MC74AC04DR2G).

Packaging Considerations: Select based on assembly requirements. Cut Tape and Digi-Reel packaging (CD74AC04M96, 74AC04SCX, MC74AC04DR2G) is suitable for automated pick-and-place assembly. Tube packaging (74AC04SC, MC74AC04DG) is appropriate for manual assembly or lower-volume production.

Frequently Asked Questions (FAQ)

Q: Can onsemi parts directly replace the obsolete CD74AC04M?

A: Yes. All onsemi substitute parts (74AC04SC, 74AC04SCX, MC74AC04DG, MC74AC04DR2G) are pin-for-pin compatible with the CD74AC04M and maintain the same 6-channel inverter logic function in 14-SOIC packaging. Electrical performance differences are within acceptable tolerances for standard logic applications.

Q: What is the difference between CD74AC04M96 and the onsemi alternatives?

A: CD74AC04M96 is manufactured by Texas Instruments and maintains the original 1.5V to 5.5V supply voltage specification and -55°C to 125°C operating temperature range. onsemi parts operate at 2V to 6V supply voltage and -40°C to 85°C temperature range. For applications requiring the extended low-voltage or temperature specifications of the original part, CD74AC04M96 is the appropriate choice.

Q: Are there differences in propagation delay between substitute parts?

A: The original CD74AC04M and CD74AC04M96 specify 6.5ns maximum propagation delay at 5V with 50pF load. onsemi substitutes specify 7ns under the same conditions. This 0.5ns difference is negligible for most digital logic applications operating at standard clock frequencies.

Q: What packaging options are available for each substitute?

A: CD74AC04M96 is available in Cut Tape and Digi-Reel packaging. onsemi 74AC04SC and MC74AC04DG are supplied in Tube packaging. onsemi 74AC04SCX and MC74AC04DR2G are available in Cut Tape and Digi-Reel packaging. Select based on assembly equipment compatibility and production volume requirements.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original CD74AC04M specifications. All parts are classified as REACH Unaffected and carry EAR99 export classification.

Q: Which substitute part offers the best inventory availability?

A: MC74AC04DR2G (onsemi) offers the highest inventory with 55,500 units in stock, followed by 74AC04SCX (onsemi) with 47,750 units. These parts are suitable for high-volume production requirements.
