Engineering Selection Recommendations

CD74ACT05M96 (Texas Instruments): Direct Texas Instruments substitute with identical electrical specifications and extended temperature range (-55°C ~ 125°C). Available in active production status with higher inventory availability. Packaging format differs (Cut Tape vs. Tube), suitable for automated assembly environments.

MC74ACT05DR2G (onsemi): Active onsemi alternative with improved propagation delay performance (8.5ns vs. 10.8ns). Restricted operating temperature range (-40°C ~ 85°C) requires evaluation against application requirements. Available in Cut Tape and Digi-Reel packaging formats for high-volume production.

MC74ACT05DG (onsemi): Manufacturer-recommended onsemi substitute with identical electrical performance to MC74ACT05DR2G. Tube packaging format matches original CD74ACT05M configuration. Suitable for applications within -40°C ~ 85°C operating range. Active production status with established supply chain.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT05DR2G and MC74ACT05DG be used interchangeably with CD74ACT05M?

A: Both onsemi parts are functionally equivalent for applications operating within -40°C ~ 85°C. The primary difference is packaging format (Cut Tape/Digi-Reel vs. Tube). If your application requires the extended temperature range of -55°C ~ 125°C, use CD74ACT05M96 instead.

Q: What is the significance of the propagation delay difference between Texas Instruments and onsemi parts?

A: Texas Instruments parts specify 10.8ns maximum propagation delay, while onsemi parts specify 8.5ns. Both meet standard 74ACT logic timing requirements. The onsemi specification represents improved performance; no circuit redesign is required when substituting.

Q: Does packaging format affect electrical performance?

A: No. Tube, Cut Tape, and Digi-Reel packaging formats are mechanical variations only. All formats contain identical die and electrical characteristics. Selection should be based on assembly process requirements and inventory management practices.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CD74ACT05M96, MC74ACT05DR2G, and MC74ACT05DG are all ROHS3 compliant with MSL Level 1 rating, meeting current environmental and reliability standards.

Q: Which substitute should I select for new designs?

A: For new designs, select based on operating temperature requirements and packaging preference. MC74ACT05DG (onsemi, Tube) or MC74ACT05DR2G (onsemi, Cut Tape) are recommended due to active production status and improved propagation delay performance. CD74ACT05M96 is preferred if extended temperature range (-55°C ~ 125°C) is required.
