Substitute Part Grouping Explanation

Substitution of the SN74F374DW is determined by strict equivalence across the following critical parameters:

• Functional Type: D-Type flip-flop with 1 element, 8-bit configuration
• Output Configuration: Tri-state, non-inverted output
• Electrical Performance: 100 MHz clock frequency, 8.5ns maximum propagation delay at specified conditions
• Trigger Mechanism: Positive edge triggering
• Supply Voltage Range: 4.5V to 5.5V
• Package Format: 20-SOIC surface mount package with identical physical dimensions
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The SN74F374DWR qualifies as a direct substitute based on identical electrical specifications, functional characteristics, and package configuration. The primary distinction is packaging format: the main part uses Tube packaging while the substitute uses Tape & Reel (TR) format. Both maintain identical component performance and pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74F374DWR is a direct functional and electrical equivalent to the SN74F374DW. Selection between these parts should be based on the following factors:

SN74F374DW (Tube Packaging): Suitable for applications with lower volume requirements or existing inventory management systems configured for tube-packaged components. Product status as Last Time Buy indicates limited future availability; existing stock of 2600 units represents the final production run.

SN74F374DWR (Tape & Reel Packaging): Recommended for new designs and high-volume production environments where automated pick-and-place assembly is standard. Active product status ensures continued availability. Current inventory of 5306 units provides superior supply security.

Both parts maintain identical electrical performance, pinout configuration, and compliance certifications (ROHS3, MSL Level 1). The choice between them is determined by packaging requirements and supply chain strategy rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can SN74F374DWR be used as a direct replacement for SN74F374DW in existing designs?

A: Yes. Both parts are electrically and functionally identical with matching pinout, electrical specifications, and performance characteristics. The only difference is packaging format (Tube versus Tape & Reel). PCB layout and circuit design require no modification.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual component handling and lower-volume applications. Tape & Reel packaging is designed for automated assembly equipment and high-volume production. Both formats contain identical components with no electrical or functional differences.

Q: Why is the SN74F374DW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The SN74F374DWR, with identical specifications and active product status, is the recommended long-term alternative for continued supply.

Q: Are there any compatibility issues when switching from SN74F374DW to SN74F374DWR?

A: No compatibility issues exist. Both parts share identical pin assignments, electrical characteristics, and functional behavior. The substitution is transparent to circuit operation.

Q: What compliance certifications apply to both parts?

A: Both SN74F374DW and SN74F374DWR are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) rating, indicating no moisture-related handling restrictions during storage or assembly.
