Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ALVC573PW,112 is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch (identical functional architecture required)
• Circuit Configuration: 8:8 channel arrangement (pin count and signal routing compatibility)
• Output Type: Tri-State (output control capability must match)
• Voltage Supply Range: 1.65V ~ 3.6V (operating voltage compatibility)
• Package / Case: 20-TSSOP (physical and electrical pin compatibility)
• Operating Temperature Range: -40°C ~ 85°C (thermal operating envelope)

The SN74LVC573APW from Texas Instruments meets all these criteria, providing functional and physical compatibility with the obsolete Nexperia component.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC573APW is a direct parametric equivalent suitable for replacing the obsolete 74ALVC573PW,112. Both components share identical electrical specifications, package geometry, and operating characteristics. The Texas Instruments component maintains active product status, ensuring long-term availability and supply chain continuity. Both parts comply with ROHS3 and REACH regulatory requirements, supporting equivalent environmental and compliance standards. The propagation delay differential (2ns versus 2.2ns) falls within acceptable engineering tolerances for transparent latch applications and does not constitute a functional limitation.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC573APW be used as a direct replacement for the 74ALVC573PW,112?

A: Yes. Both components are parametrically equivalent across all critical specifications including logic type, circuit configuration, output type, voltage supply range, package geometry, and operating temperature range. Direct pin-for-pin substitution is supported.

Q: Are there differences in propagation delay between these parts?

A: The 74ALVC573PW,112 specifies 2.2ns propagation delay while the SN74LVC573APW specifies 2ns. This 0.2ns difference is within normal manufacturing tolerances and does not affect functional compatibility in transparent latch applications.

Q: Do both parts require identical PCB layout considerations?

A: Yes. Both components use the 20-TSSOP package with identical pin assignments and physical dimensions (0.173", 4.40mm width). PCB layouts designed for the 74ALVC573PW,112 require no modification for the SN74LVC573APW.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are regulatory certifications equivalent between the two parts?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory standards.
