Engineering Selection Recommendations

All three substitute parts are Active product status components from established semiconductor manufacturers. Selection between substitutes should be based on the following considerations:

74ACT00SCX (Fairchild Semiconductor): This part offers improved propagation delay performance (9ns versus 13.2ns) and lower quiescent current (2 µA versus 4 µA). However, the operating temperature range is limited to -40°C ~ 85°C, which is narrower than the original CD74ACT00M96. This part is suitable for applications operating within the -40°C to 85°C range where lower power consumption and faster switching are beneficial.

MC74ACT00DG (onsemi): This part maintains the full operating temperature range of -55°C ~ 125°C matching the original component, with improved propagation delay (9ns) and ROHS3 compliance. Packaging is specified as Tube. This part is suitable for applications requiring the extended temperature range and is compliant with environmental regulations.

MC74ACT00DR2G (onsemi): This part also maintains the full operating temperature range of -55°C ~ 125°C with improved propagation delay (9ns) and ROHS3 compliance. Packaging is specified as Tape & Reel (TR). This part is suitable for high-volume production environments requiring tape and reel packaging.

All substitute parts maintain electrical compatibility with the original CD74ACT00M96 in terms of supply voltage, output current, and input logic levels. The choice between substitutes depends on packaging requirements, temperature range constraints, and performance specifications for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT00SCX directly replace the CD74ACT00M96 in all applications?

A: The 74ACT00SCX is electrically compatible with the CD74ACT00M96 for applications operating within the -40°C to 85°C temperature range. If your application requires operation below -40°C or above 85°C, the onsemi alternatives (MC74ACT00DG or MC74ACT00DR2G) are required to maintain the full -55°C to 125°C operating range.

Q: What is the difference between MC74ACT00DG and MC74ACT00DR2G?

A: Both parts are functionally and electrically identical. The primary difference is packaging: MC74ACT00DG is supplied in Tube packaging, while MC74ACT00DR2G is supplied in Tape & Reel (TR) packaging. Selection depends on your procurement and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: The CD74ACT00M96, MC74ACT00DG, and MC74ACT00DR2G are all ROHS3 compliant. The 74ACT00SCX RoHS status is not specified in the available documentation.

Q: Do all parts have the same propagation delay?

A: No. The CD74ACT00M96 has a maximum propagation delay of 13.2ns at 5V with 50pF load. The three substitute parts (74ACT00SCX, MC74ACT00DG, and MC74ACT00DR2G) all have a maximum propagation delay of 9ns at 5V with 50pF load, representing improved switching performance.

Q: Are the package dimensions identical across all parts?

A: Yes. All parts use the 14-SOIC package with dimensions of 0.154" width and 3.90mm width, ensuring mechanical compatibility in PCB layouts.

Q: What is the moisture sensitivity level for these parts?

A: The CD74ACT00M96, MC74ACT00DG, and MC74ACT00DR2G all have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions. The 74ACT00SCX MSL is not specified.
