Substitute Part Grouping Explanation
Substitution of the 74LVC2G74GD,125 is determined by strict equivalence across the following critical parameters:
Electrical Parameters (Must Match):
- Clock Frequency: 200 MHz
- Max Propagation Delay @ 5V, 50pF: 4.1 ns
- Trigger Type: Positive Edge
- Current - Output High/Low: 32 mA / 32 mA
- Voltage - Supply: 1.65V ~ 5.5V
- Input Capacitance: 4 pF
- Operating Temperature: -40°C ~ 125°C (TA)
Functional Parameters (Must Match):
- Type: D-Type Flip Flop
- Output Type: Complementary
- Number of Elements: 1
- Number of Bits per Element: 1

Engineering Selection Recommendations
Primary Substitutes (Active Status, ROHS3 Compliant):
The 74LVC2G74GN,115, 74LVC2G74GS,115, and 74LVC2G74GT,115 are direct functional and package equivalents with active product status. These parts maintain identical electrical specifications and the same 8-XFDFN package footprint. Selection among these three should be based on packaging format availability: 74LVC2G74GN,115 (Bulk), 74LVC2G74GS,115 (Tape & Reel), or 74LVC2G74GT,115 (Bulk).
Alternative Package Option:
The 74LVC2G74DC,125 provides electrical equivalence with active product status and ROHS3 compliance but uses an 8-VFSOP package instead of 8-XFDFN. This substitute is suitable only if PCB layout accommodates the larger 8-VFSOP footprint (0.091" width, 2.30mm).
Automotive-Grade Option:
The 74LVC1G74GT-Q100X is qualified to AEC-Q100 automotive standards with active product status and ROHS3 compliance. This part is appropriate for automotive applications requiring automotive-grade components.
Secondary Substitutes (Active Status, Compliance Not Fully Specified):
The 74LVC1G74GN,115 and 74LVC1G74GT,115 meet all electrical and functional requirements with active product status but do not specify RoHS compliance status in the provided data. These parts are suitable for applications where RoHS compliance documentation is not required.
Frequently Asked Questions (FAQ)
Q: Can I use 74LVC1G74 series parts as substitutes for 74LVC2G74GD,125?
A: Yes. The 74LVC1G74GN,115, 74LVC1G74GS,115, and 74LVC1G74GT,115 are parametric equivalents with identical electrical specifications, clock frequency, propagation delay, supply voltage range, output current, and operating temperature. All maintain the same 8-XFDFN package footprint and complementary output configuration.
Q: What is the difference between 74LVC2G74GS,115 and 74LVC2G74GN,115?
A: Both parts are electrically and functionally identical. The difference is packaging format: 74LVC2G74GS,115 is supplied in Tape & Reel format, while 74LVC2G74GN,115 is supplied in Bulk format. Selection depends on procurement and assembly requirements.
Q: Is 74LVC2G74DC,125 a direct replacement?
A: 74LVC2G74DC,125 is electrically equivalent but uses an 8-VFSOP package instead of 8-XFDFN. This larger package may require PCB layout modifications. Use only if your design accommodates the 8-VFSOP footprint.
Q: Why is the original 74LVC2G74GD,125 marked as obsolete?
A: The 74LVC2G74GD,125 is obsolete, but multiple active equivalents exist from both Nexperia and NXP. The 74LVC2G74GN,115, 74LVC2G74GS,115, and 74LVC2G74GT,115 provide identical functionality with current product support.
Q: Do all substitute parts meet RoHS3 compliance?
A: The 74LVC2G74GN,115, 74LVC2G74GS,115, 74LVC2G74GT,115, 74LVC2G74DC,125, and 74LVC1G74GT-Q100X are confirmed ROHS3 compliant. The 74LVC1G74GN,115 and 74LVC1G74GT,115 do not specify RoHS status in the provided data.
Q: Can I use 74LVC1G74GT-Q100X in non-automotive applications?
A: Yes. The 74LVC1G74GT-Q100X meets all electrical and functional requirements for general-purpose applications. Automotive qualification (AEC-Q100) is an additional certification that does not restrict use in non-automotive designs.
Q: What is the maximum operating frequency for all listed parts?
A: All listed parts, including the original 74LVC2G74GD,125 and all substitutes, support a clock frequency of 200 MHz with a maximum propagation delay of 4.1 ns at 5V with 50pF load.
