Frequently Asked Questions (FAQ)

Q: Are the 74ACT11373NT and 74ACT11373DWR electrically interchangeable?

A: Yes. Both parts share identical electrical specifications, including supply voltage range (4.5V ~ 5.5V), propagation delay (8.5ns), output current capability (24mA), and operating temperature range (-40°C ~ 85°C). Functional equivalence is complete.

Q: What is the primary difference between these parts?

A: The primary difference is packaging and mounting technology. The 74ACT11373NT uses a 24-pin DIP package for through-hole mounting, while the 74ACT11373DWR uses a 24-pin SOIC package for surface-mount assembly. Pin-to-pin functionality remains identical.

Q: Can I use the 74ACT11373DWR as a direct replacement in a through-hole PCB design?

A: No. The 74ACT11373DWR requires surface-mount assembly and cannot be directly installed in through-hole footprints. PCB redesign and assembly process modification are necessary for implementation.

Q: Why is the 74ACT11373NT classified as obsolete?

A: The 74ACT11373NT has reached end-of-life status. The 74ACT11373DWR represents the active product continuation within the 74ACT11373 family, offering equivalent performance in a surface-mount package format aligned with current manufacturing standards.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 74ACT11373NT and 74ACT11373DWR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
