Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC2G74DCUTG4 is determined by the following critical parameters:

Functional Equivalence Requirements:

• D-Type flip-flop architecture with 1 element, 1 bit per element
• Complementary output configuration
• Set/Preset and Reset functionality
• Positive edge trigger mechanism
• 74LVC logic family classification

Electrical Compatibility Requirements:

• Supply voltage range: 1.65V ~ 5.5V (must encompass or match)
• Operating temperature range: -40°C ~ 125°C
• Output current capability: 32mA high and low
• Package / Case: 8-VFSOP (0.091", 2.30mm Width)
• Surface mount mounting type

Compliance Requirements:

• ROHS3 Compliant
• REACH Unaffected status

The substitute parts identified below meet all functional and electrical compatibility criteria. Variations in clock frequency, propagation delay, quiescent current, and input capacitance are within acceptable engineering tolerances for this component category and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC2G74DCUT (Parametric Equivalent): This Texas Instruments part maintains identical electrical specifications to the main part number while offering active product status. The transition from tube to tape & reel packaging accommodates high-volume production environments. This substitute is the direct functional replacement with no performance trade-offs.

74LVC2G74DC,125 (Upgrade): Manufactured by Nexperia USA Inc., this part offers enhanced performance characteristics including 200 MHz clock frequency (versus 140 MHz), reduced propagation delay of 4.1 ns (versus 5.1 ns), and improved input capacitance of 4 pF (versus 5 pF). Quiescent current increases to 40 µA. This upgrade path is suitable for applications requiring higher speed performance while maintaining full electrical compatibility and compliance certifications.

74LVC1G74DC,125 (MFR Recommended): Also from Nexperia USA Inc., this part provides the lowest quiescent current at 4 µA, making it optimal for power-constrained applications. It matches the 200 MHz clock frequency and 4.1 ns propagation delay of the upgrade option. This selection is recommended for designs prioritizing low-power operation without sacrificing speed performance.

All three substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical package specifications, ensuring direct PCB compatibility and regulatory compliance continuity.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC2G74DCUT be used as a direct replacement for SN74LVC2G74DCUTG4?

A: Yes. SN74LVC2G74DCUT is a parametric equivalent with identical electrical specifications, functional architecture, and package configuration. The only difference is packaging format (tape & reel versus tube) and active product status. No circuit modifications are required.

Q: What is the difference between the Nexperia parts and the Texas Instruments options?

A: Both manufacturers produce 74LVC logic components meeting identical functional and electrical standards. The Nexperia parts (74LVC2G74DC,125 and 74LVC1G74DC,125) offer enhanced performance metrics: higher clock frequency (200 MHz versus 140 MHz) and faster propagation delay (4.1 ns versus 5.1 ns). The 74LVC1G74DC,125 additionally provides the lowest quiescent current at 4 µA.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All substitute parts use the identical 8-VFSOP (0.091", 2.30mm Width) surface mount package. PCB footprints, reflow profiles, and assembly processes remain unchanged. Packaging format differences (tube, tape & reel, cut tape) affect only supply chain and handling procedures, not component functionality or board-level compatibility.

Q: Which substitute should be selected for power-sensitive applications?

A: The 74LVC1G74DC,125 is recommended for power-constrained designs, offering the lowest quiescent current at 4 µA while maintaining 200 MHz clock frequency and 4.1 ns propagation delay performance.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited) and ECCN/HTSUS classifications as the original part.

Q: What is the inventory availability status of these substitutes?

A: SN74LVC2G74DCUT has 3,610 units in stock. 74LVC2G74DC,125 has 19,788 units in stock. 74LVC1G74DC,125 has 3,221 units in stock. All parts are currently active products with established supply chains.
