Substitute Part Grouping Explanation

Substitution of the N74F374DB,112 is determined by strict equivalence across the following critical parameters:

• Logic Function: D-Type flip-flop with 1 element, 8-bit configuration
• Output Configuration: Tri-state, non-inverted outputs
• Trigger Mechanism: Positive edge-triggered operation
• Package Compatibility: 20-SSOP surface mount package with identical physical dimensions (0.209", 5.30mm width)
• Electrical Specifications: Supply voltage range 4.5V to 5.5V, operating temperature 0°C to 70°C
• Compliance Standards: ROHS3 compliant, REACH unaffected status

The SN74F374DBR from Texas Instruments meets all substitution criteria within the 74F logic series, maintaining functional and electrical equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74F374DBR from Texas Instruments is the direct functional equivalent for the obsolete N74F374DB,112. Both components maintain identical electrical characteristics, package specifications, and compliance certifications. The primary distinction is product status: the Texas Instruments variant is actively manufactured and supported, whereas the NXP part is obsolete.

For new designs and ongoing system support, the SN74F374DBR is the appropriate selection. Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance across manufacturing and deployment environments. The identical 20-SSOP package and surface mount configuration enable direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74F374DBR directly replace the N74F374DB,112 in existing designs?

A: Yes. Both components share identical package specifications (20-SSOP), electrical ratings (4.5V to 5.5V supply), output configuration (tri-state, non-inverted), and trigger mechanism (positive edge). Direct substitution is functionally and electrically equivalent.

Q: What is the significance of the product status difference?

A: The N74F374DB,112 is classified as obsolete, indicating NXP has discontinued manufacturing. The SN74F374DBR maintains active production status, ensuring long-term availability and supply chain reliability for component procurement.

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

A: The N74F374DB,112 specifies 7.5ns maximum propagation delay at 5V with 50pF load, while the SN74F374DBR specifies 8.5ns under identical conditions. Both values fall within acceptable operating parameters for 74F series logic applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the N74F374DB,112 and SN74F374DBR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and deployment.

Q: What packaging options are available for the substitute part?

A: The SN74F374DBR is supplied in Tape & Reel (TR) packaging, standard for surface mount production environments. The 20-SSOP package dimensions remain consistent with the original component.
