• Voltage - Supply: 4.5V ~ 5.5V
• Independent Circuits: 1
• Current - Output High, Low: 24mA, 24mA
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 20-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The SN74ACT563N from Texas Instruments meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent. Both parts share identical logic architecture, pin configuration, voltage specifications, output current ratings, and thermal operating range within the 20-DIP package format.

Parameter Comparison

Engineering Selection Recommendations

The SN74ACT563N is the qualified substitute for the 74ACTQ563PC based on complete electrical and mechanical parameter alignment. The substitute part is manufactured by Texas Instruments and maintains active product status, ensuring continued availability and supply chain stability. The SN74ACT563N carries ROHS3 compliance certification, meeting current environmental and regulatory standards. Both parts are REACH Unaffected and classified under ECCN EAR99 with identical HTSUS coding (8542.39.0001), confirming regulatory equivalence.

The propagation delay differential (1ns versus 6.5ns) reflects manufacturing process variations between onsemi and Texas Instruments but does not affect functional substitution within standard logic circuit applications operating at the specified voltage and temperature parameters.

Frequently Asked Questions (FAQ)

Q: Can the SN74ACT563N directly replace the 74ACTQ563PC in existing circuit designs?

A: Yes. Both parts share identical logic architecture, pin configuration, voltage specifications, output current ratings, and thermal operating range. Direct pin-for-pin substitution is supported within the 20-DIP package format.

Q: What is the significance of the propagation delay difference between these parts?

A: The 74ACTQ563PC specifies 1ns propagation delay while the SN74ACT563N specifies 6.5ns. This difference reflects manufacturing process variations between manufacturers but does not affect functional compatibility in standard logic applications operating within the specified voltage and temperature parameters.

Q: Are there any compliance or regulatory differences between these parts?

A: The SN74ACT563N carries ROHS3 compliance certification, while the 74ACTQ563PC does not specify RoHS status. Both parts are REACH Unaffected and share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and procurement purposes.

Q: Why is the 74ACTQ563PC listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The SN74ACT563N from Texas Instruments provides functional continuity for applications requiring D-Type Transparent Latch logic with 8:8 circuit configuration and tri-state output in 20-DIP packaging.

Q: Are packaging options available for the substitute part?

A: The SN74ACT563N is supplied in tube packaging format. Both the original and substitute parts utilize 20-DIP (0.300", 7.62mm) through-hole package configuration, ensuring mechanical compatibility with existing PCB designs.
