Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74AVC16374DGG are identified based on the following critical parameters that determine functional and mechanical compatibility:

Functional Compatibility Criteria:

• Series designation (74AVC)
• Type (D-Type Flip-Flop)
• Number of elements (2) and bits per element (8)
• Output type (Tri-State, Non-Inverted)
• Trigger type (Positive Edge)
• Max propagation delay at 3.3V, 30pF load (3.3 ns)
• Output current capability (12 mA / 12 mA)
• Operating temperature range (-40°C ~ 85°C)

Mechanical Compatibility Criteria:

• Mounting type (Surface Mount)
• Package family (48-TFSOP)
• Pin count and signal assignments

Compliance Criteria:

• RoHS3 compliance
• REACH status
• Moisture sensitivity level

Substitute parts are grouped into two categories: direct manufacturer equivalents (identical packaging) and similar parts (alternative packaging within the same family).

Engineering Selection Recommendations

SN74AVC16374DGGR (Texas Instruments - Direct Equivalent)

The SN74AVC16374DGGR is a direct functional and mechanical equivalent to the 74AVC16374DGG. Both parts share identical package dimensions (48-TFSOP, 0.240" width), pin assignments, and electrical performance specifications. The SN74AVC16374DGGR is manufactured by Texas Instruments and maintains active product status, ensuring long-term availability and supply chain continuity. This part is recommended as the primary substitute for new designs and production continuity.

SN74AVC16374DGVR (Texas Instruments - Alternative Package)

The SN74AVC16374DGVR is functionally equivalent but utilizes a narrower 48-TVSOP package (0.173" width) compared to the original 48-TFSOP (0.240" width). This part is suitable for applications where reduced board space is a design requirement. PCB layout modifications are necessary to accommodate the different package footprint. The SN74AVC16374DGVR is manufactured by Texas Instruments with active product status.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 (unlimited moisture sensitivity), ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the SN74AVC16374DGGR be used as a direct replacement for the 74AVC16374DGG?

A: Yes. The SN74AVC16374DGGR is a direct functional and mechanical equivalent. Both parts feature identical 48-TFSOP packaging, pin configuration, and electrical specifications. No PCB modifications are required for substitution.

Q: What is the difference between the SN74AVC16374DGGR and SN74AVC16374DGVR?

A: The primary difference is package width. The SN74AVC16374DGGR uses a 48-TFSOP package (0.240" width), while the SN74AVC16374DGVR uses a 48-TVSOP package (0.173" width). Both are functionally equivalent, but the narrower TVSOP package requires PCB footprint redesign. Electrical performance and pin assignments remain identical.

Q: Are there voltage supply differences between the original and substitute parts?

A: The original 74AVC16374DGG supports 1.2V ~ 3.6V supply range, while both Texas Instruments substitutes support 1.4V ~ 3.6V. For applications requiring operation below 1.4V, the original Nexperia part may be necessary. For standard 3.3V and 5V logic applications, both substitutes are fully compatible.

Q: What is the clock frequency difference, and does it affect compatibility?

A: The original 74AVC16374DGG specifies 350 MHz clock frequency, while the Texas Instruments substitutes specify 200 MHz. Both exceed typical digital logic application requirements. The max propagation delay specification (3.3 ns @ 3.3V, 30pF) is identical across all parts, ensuring timing compatibility in standard applications.

Q: Do the substitute parts have the same input capacitance?

A: The original part specifies 5 pF input capacitance, while the Texas Instruments substitutes specify 3 pF. Lower input capacitance in the substitutes may provide marginal benefits in high-frequency applications but does not affect functional compatibility.

Q: Are all parts RoHS3 compliant?

A: Yes. The original 74AVC16374DGG and both substitute parts (SN74AVC16374DGGR and SN74AVC16374DGVR) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available for procurement?

A: The SN74AVC16374DGGR is available in Tape & Reel (TR) packaging, suitable for automated assembly. The SN74AVC16374DGVR is available in bulk packaging. Packaging selection depends on production volume and assembly process requirements.
