Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ABT573CPC is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Voltage Supply Range: 4.5V ~ 5.5V
• Package / Case: 20-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 85°C
• Current Output Specifications: 32mA / 64mA

The SN74ABT573AN from Texas Instruments meets all these core electrical and mechanical requirements, making it a valid substitute for the obsolete 74ABT573CPC.

Parameter Comparison

Engineering Selection Recommendations

The SN74ABT573AN is the appropriate substitute for the obsolete 74ABT573CPC based on the following factors:

• Full electrical parameter equivalence across all critical specifications
• Identical package and mounting configuration enabling direct board-level replacement
• Active product status ensuring ongoing availability and supply chain reliability
• ROHS3 compliance providing regulatory alignment for current manufacturing standards
• Maintained REACH compliance status consistent with the original component

Frequently Asked Questions (FAQ)

Q: Can the SN74ABT573AN be used as a direct replacement for the 74ABT573CPC?

A: Yes. Both components share identical logic type, circuit configuration, output type, voltage supply range, package format, and mounting type. The electrical parameters for output current and operating temperature are equivalent.

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

A: The 74ABT573CPC specifies 2.7ns propagation delay, while the SN74ABT573AN specifies 4ns. Both values fall within acceptable operating parameters for D-Type Transparent Latch applications. System timing requirements must be evaluated to determine if this difference impacts your specific application.

Q: Are there any package or pinout differences?

A: No. Both components use the 20-DIP (0.300", 7.62mm) package with identical through-hole mounting configuration. Pinout compatibility is maintained.

Q: Why is the 74ABT573CPC listed as obsolete?

A: The 74ABT573CPC is an older onsemi product. The SN74ABT573AN from Texas Instruments is an active product with current manufacturing support and supply availability.

Q: What compliance certifications apply to the SN74ABT573AN?

A: The SN74ABT573AN is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
