Parameter Comparison

Engineering Selection Recommendations

SN74ALS573CDWR is classified as a direct manufacturer substitute. This part maintains all critical electrical and mechanical parameters while offering improved propagation delay performance (2ns versus 6ns). The component carries active product status from Texas Instruments, ensuring ongoing availability and manufacturing support. Full compliance with ROHS3 and REACH regulations is maintained.

SN74ALS373ADWR is classified as a parametric equivalent. This part matches all core electrical specifications and physical package requirements of the SN74ALS580BDWR, including identical propagation delay timing (6ns). The component is actively manufactured by Texas Instruments with equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected).

Both substitute parts are suitable for direct replacement in applications currently utilizing the obsolete SN74ALS580BDWR, provided system timing requirements are compatible with the specified propagation delay characteristics.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS573CDWR be used as a direct replacement for SN74ALS580BDWR?

A: Yes. The SN74ALS573CDWR maintains all critical electrical and mechanical parameters required for functional compatibility. The improved propagation delay (2ns) represents enhanced performance and does not create compatibility issues in standard applications.

Q: What is the difference between the two substitute parts?

A: Both parts are functionally equivalent D-Type Transparent Latch ICs with 8:8 configuration and tri-state output. The primary distinction is propagation delay: SN74ALS573CDWR operates at 2ns while SN74ALS373ADWR matches the original 6ns specification. Selection depends on system timing requirements.

Q: Are the substitute parts available in the same package?

A: Yes. All three parts utilize the 20-SOIC (0.295", 7.50mm Width) surface mount package, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both SN74ALS573CDWR and SN74ALS373ADWR are ROHS3 Compliant and REACH Unaffected, matching the compliance profile of the original SN74ALS580BDWR.

Q: Why is the original part classified as obsolete?

A: The SN74ALS580BDWR has been discontinued by Texas Instruments. The identified substitute parts represent the current active alternatives that fulfill the same functional requirements.
