74LVTH574D,118 Equivalent & Substitute Parts

Part Overview

The 74LVTH574D,118 is a single-element D-type flip-flop logic integrated circuit manufactured by NXP USA Inc., designed for 8-bit positive edge-triggered applications. This component operates at 150 MHz clock frequency with tri-state, non-inverted output configuration in a 20-SOIC surface mount package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts must maintain identical functional specifications, electrical performance, and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitute parts for the 74LVTH574D,118 are classified based on the following substitution criteria:

Critical Parameters for Substitution:

• D-Type flip-flop function with 1 element, 8 bits per element
• Tri-state, non-inverted output configuration
• Positive edge trigger type
• 150 MHz clock frequency capability
• 2.7V ~ 3.6V supply voltage range
• -40°C ~ 85°C operating temperature range
• 20-SOIC (0.295", 7.50mm Width) package
• Surface mount mounting type
• ROHS3 compliance and REACH unaffected status

Substitute Categories:

1. Direct Manufacturer Equivalent (SN74LVT574DW): Texas Instruments part with identical electrical and mechanical specifications. Series designation differs (74LVT vs. 74LVTH) but maintains all critical parameters. Active product status ensures ongoing availability.

2. Manufacturer Recommended Equivalents (SN74LVTH574DW, SN74LVTH574DWR): Texas Instruments parts with matching series designation (74LVTH). These represent the active production equivalents to the obsolete NXP part. Available in different packaging formats (Tube and Tape & Reel).

3. Parametric Equivalent (SN74LVT574DWR): Texas Instruments part with identical functional and electrical parameters in Tape & Reel packaging. Series designation differs but all critical substitution parameters align.

Engineering Selection Recommendations

Primary Recommendation: SN74LVTH574DWR (Texas Instruments)

The SN74LVTH574DWR is the preferred substitute for the obsolete 74LVTH574D,118. This part maintains identical series designation (74LVTH), ensuring design continuity with the original component. It is an active product with high inventory availability (91,697 pcs), supplied in Tape & Reel packaging suitable for automated assembly. The part demonstrates improved propagation delay performance (4.5ns vs. 5.9ns) and reduced input capacitance (3 pF vs. 4 pF), providing enhanced electrical characteristics. Full ROHS3 compliance and REACH unaffected status satisfy regulatory requirements.

Secondary Recommendation: SN74LVTH574DW (Texas Instruments)

The SN74LVTH574DW offers identical functional and electrical specifications to the primary recommendation, with availability in Tube packaging. This option is suitable for lower-volume applications or manual assembly processes. Inventory availability is 1,240 pcs.

Alternative Recommendation: SN74LVT574DW or SN74LVT574DWR (Texas Instruments)

The 74LVT series parts (SN74LVT574DW and SN74LVT574DWR) provide complete parametric equivalence with identical propagation delay (5.9ns) and input capacitance (4 pF) matching the original part. These parts are suitable for applications where series designation flexibility is acceptable. The SN74LVT574DWR offers high inventory (2,200 pcs) in Tape & Reel format.

All substitute parts are active products with confirmed availability, ROHS3 compliance, and REACH unaffected status, ensuring regulatory compliance and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74LVTH574D,118 with any of the recommended substitutes?

A: Yes. All recommended substitutes maintain identical functional specifications, electrical parameters, and 20-SOIC package dimensions. Direct pin-for-pin replacement is supported without circuit modification.

Q: What is the difference between the 74LVTH and 74LVT series parts?

A: Both series meet the critical substitution parameters for this application. The 74LVTH series (SN74LVTH574DW, SN74LVTH574DWR) maintains the original series designation. The 74LVT series (SN74LVT574DW, SN74LVT574DWR) provides parametric equivalence with identical propagation delay and output drive characteristics. Series selection depends on design documentation requirements and supply chain preferences.

Q: Are there packaging format differences among the substitutes?

A: Yes. SN74LVTH574DW and SN74LVT574DW are supplied in Tube packaging. SN74LVTH574DWR and SN74LVT574DWR are supplied in Tape & Reel (TR) format. Tube packaging is suitable for manual assembly and lower volumes. Tape & Reel format is optimized for automated pick-and-place assembly and higher production volumes. Both formats contain identical components.

Q: Do the substitute parts have better performance than the original?

A: The 74LVTH series substitutes (SN74LVTH574DW, SN74LVTH574DWR) demonstrate improved propagation delay (4.5ns vs. 5.9ns) and lower input capacitance (3 pF vs. 4 pF). The 74LVT series substitutes maintain identical propagation delay (5.9ns) and input capacitance (4 pF) to the original part. All substitutes meet or exceed the original specifications.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. All recommended substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Which substitute should I select for new designs?

A: For new designs, SN74LVTH574DWR is recommended as the primary choice due to active product status, high inventory availability, improved electrical performance, and Tape & Reel packaging suitable for automated manufacturing. This part ensures long-term supply continuity and design flexibility.
