Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVC573D,112 is determined by strict alignment across the following critical parameters:

• Logic Type: D-Type Transparent Latch configuration
• Circuit Configuration: 8:8 channel arrangement
• Output Type: Tri-State capability
• Supply Voltage Range: 1.65V ~ 3.6V compatibility
• Independent Circuits: Single channel (1)
• Package / Case: 20-SOIC form factor with identical physical dimensions
• Output Current Capability: 24mA minimum for both high and low states
• Operating Temperature Range: -40°C ~ 85°C minimum coverage
• RoHS and REACH Compliance: ROHS3 Compliant and REACH Unaffected status

The SN74LVC573ADW from Texas Instruments meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC573ADW qualifies as a direct parametric equivalent to the 74ALVC573D,112. Both components maintain identical electrical specifications across supply voltage, output current, operating temperature range, and circuit configuration. The SN74LVC573ADW offers the additional advantage of active product status, ensuring continued availability and manufacturing support. Both parts satisfy ROHS3 compliance and REACH regulatory requirements, making either suitable for applications requiring environmental and regulatory adherence. The propagation delay differential (2ns versus 2.2ns) represents a performance improvement in the substitute part and does not introduce compatibility concerns. Package compatibility is confirmed through identical 20-SOIC form factor specifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC573ADW directly replace the 74ALVC573D,112 in existing designs?

A: Yes. Both parts share identical logic type, circuit configuration, output type, supply voltage range, output current capability, operating temperature range, and package form factor. The SN74LVC573ADW demonstrates faster propagation delay, which is compatible with applications designed for the original part.

Q: Are there package compatibility concerns when substituting these parts?

A: No. Both the 74ALVC573D,112 and SN74LVC573ADW use the 20-SOIC package with identical physical dimensions (0.295", 7.50mm Width). PCB footprints and mounting procedures remain unchanged.

Q: What is the significance of the product status difference between these parts?

A: The 74ALVC573D,112 is classified as obsolete, while the SN74LVC573ADW maintains active status. Active status indicates ongoing manufacturing support, established supply chains, and continued availability for procurement. This distinction is relevant for long-term production planning and component sourcing strategy.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 74ALVC573D,112 and SN74LVC573ADW are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: How does the propagation delay difference affect system performance?

A: The SN74LVC573ADW exhibits a 2ns propagation delay compared to the 74ALVC573D,112 at 2.2ns. This 0.2ns improvement represents faster signal transition and does not introduce compatibility issues in applications designed for the original specification.
