Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74ACT563PW are identified based on strict electrical and mechanical parameter alignment. The critical parameters determining substitution eligibility are:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Supply Voltage Range: 4.5V ~ 5.5V
• Independent Circuits: 1
• Output Current Capability: 24mA (High and Low)
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 20-TSSOP
• Mounting Type: Surface Mount

Substitutes are grouped into two categories: MFR Recommended (same base product with different packaging) and Parametric Equivalent (functionally equivalent with minor specification variations).

Parameter Comparison

Engineering Selection Recommendations

SN74ACT563PWR is the primary recommended substitute for the SN74ACT563PW. Both parts share identical electrical specifications and the same 20-TSSOP package. The SN74ACT563PWR differs only in packaging format (Tape & Reel versus Tube) and maintains Active product status, ensuring continued availability and supply chain stability. This part is suitable for direct replacement in all applications where the main part was specified.

SN74ACT573PW is a parametric equivalent offering functional compatibility with a minor propagation delay specification of 6ns compared to 6.5ns in the main part. This represents a performance improvement and does not introduce compatibility issues. However, this part is discontinued at DiGi Electronics, which may limit future procurement options. Selection of this part should account for long-term availability constraints.

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

Frequently Asked Questions (FAQ)

Q: Can SN74ACT563PWR be used as a direct replacement for SN74ACT563PW?

A: Yes. The SN74ACT563PWR is electrically and mechanically identical to the SN74ACT563PW. The only difference is the packaging format (Tape & Reel versus Tube). Both parts are suitable for direct substitution in PCB assembly and design applications.

Q: What is the difference between the packaging formats?

A: SN74ACT563PW is supplied in Tube packaging, while SN74ACT563PWR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes, while Tube packaging is typically used for manual handling or smaller quantity orders. The electrical and mechanical specifications are identical.

Q: Is SN74ACT573PW compatible with designs using SN74ACT563PW?

A: SN74ACT573PW meets all critical electrical parameters required for substitution, including supply voltage, output current, operating temperature range, and package type. The propagation delay of 6ns is faster than the specified 6.5ns, which does not introduce compatibility issues. However, this part is discontinued at DiGi Electronics, limiting future availability.

Q: Why is the main part listed as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has announced the end of production for this part. This necessitates identifying substitute parts to ensure design continuity. The SN74ACT563PWR, which maintains Active status, is the recommended alternative for ongoing procurement.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both SN74ACT563PWR and SN74ACT573PW are ROHS3 compliant, meeting environmental and regulatory requirements for electronic components.

Q: What does MSL Level 1 mean for storage and handling?

A: MSL Level 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. These parts do not require baking or desiccant storage conditions prior to assembly.
