Substitute Part Grouping Explanation
Substitution of the MC74ACT05DTR2 is based on strict equivalence across the following critical parameters:
- Logic type and circuit configuration (6-channel inverter with open drain)
- Electrical specifications (supply voltage, quiescent current, output current, input logic levels, propagation delay)
- Operating temperature range (-40°C ~ 85°C)
- Physical package (14-TSSOP surface mount)
- Base product number (74ACT05)
The MC74ACT05DTR2G qualifies as a direct substitute because it maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Engineering Selection Recommendations
The MC74ACT05DTR2G is the direct substitute for the obsolete MC74ACT05DTR2. Selection of the MC74ACT05DTR2G is justified by:
- Identical electrical and mechanical specifications ensuring pin-for-pin and functional compatibility
- Active product status providing long-term availability and supply chain stability
- ROHS3 compliance versus non-compliant status of the original part, meeting current regulatory requirements
- Tape & Reel packaging suitable for automated assembly processes
For applications requiring the MC74ACT05DTR2, transition to the MC74ACT05DTR2G without design modification.
Frequently Asked Questions (FAQ)
Q: Can MC74ACT05DTR2G be used as a direct replacement for MC74ACT05DTR2?
A: Yes. Both parts share identical electrical specifications, pin configuration, and package dimensions. The MC74ACT05DTR2G is the active equivalent.
Q: What is the difference between MC74ACT05DTR2 and MC74ACT05DTR2G?
A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (bulk versus Tape & Reel). Electrical and functional performance are identical.
Q: Are there packaging considerations when switching to MC74ACT05DTR2G?
