Substitute Part Grouping Explanation

Substitution eligibility for the CLVTH16373MGQLREP is determined by the following critical parameters:

• Logic Type: D-Type Transparent Latch (must match)
• Circuit Configuration: 8:8 (must match)
• Independent Circuits: 2 (must match)
• Output Type: Tri-State (must match)
• Voltage - Supply: 2.7V ~ 3.6V (must match)
• Delay Time - Propagation: 2.9ns (must match)
• Current - Output High, Low: 32mA, 64mA (must match)
• Base Product Number: CLVTH16373 (must match)

The CLVTH16373IDGGREP qualifies as a direct functional substitute based on identical electrical specifications and core logic architecture. Variations in package type (56-VFBGA to 48-TSSOP), operating temperature range, and product status do not affect functional equivalence when electrical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The CLVTH16373IDGGREP is the primary substitute for the obsolete CLVTH16373MGQLREP. This recommendation is based on:

• Identical electrical performance across all critical parameters
• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance, meeting current regulatory requirements for new designs
• Equivalent functional capability for all D-Type transparent latch applications

The operating temperature range of the substitute (-40°C ~ 85°C) is narrower than the original part (-55°C ~ 125°C). Applications requiring the extended temperature range of the original part must evaluate this limitation against system requirements.

The package change from 56-VFBGA to 48-TFSOP requires PCB layout modification and design validation. Pin-to-pin functional mapping must be verified during integration.

Frequently Asked Questions (FAQ)

Q: Can CLVTH16373IDGGREP directly replace CLVTH16373MGQLREP without design changes?

A: Electrical functionality is identical. However, the package format differs (56-VFBGA vs. 48-TFSOP), requiring PCB redesign and footprint modification. Pin configuration must be mapped during integration.

Q: What is the significance of the operating temperature range difference?

A: The original part operates from -55°C to 125°C, while the substitute operates from -40°C to 85°C. Applications requiring operation below -40°C or above 85°C must evaluate alternative solutions or confirm system temperature requirements do not exceed these limits.

Q: Does RoHS3 compliance of the substitute affect compatibility?

A: RoHS3 compliance is a regulatory advantage for new designs and systems subject to environmental regulations. The original part's non-compliance status does not affect electrical performance but may restrict use in regulated applications.

Q: Are there other substitutes available for this part?

A: The provided substitute list identifies CLVTH16373IDGGREP as the manufacturer-recommended equivalent. Additional cross-references (74LVT16373MTDX, 74LVT16373ADGG) may exist but are not included in this engineering reference based on provided data.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.
