Engineering Selection Recommendations

Primary Recommendation for Direct Replacement:

74LVC2G74GS,115 is the preferred direct substitute. It maintains identical electrical specifications, clock frequency, propagation delay, and supply voltage range as the obsolete 74LVC2G74GF,115. The part is in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Tape & Reel packaging supports automated assembly processes.

Alternative Direct Substitutes:

74LVC2G74GN,115 and 74LVC2G74GT,115 provide equivalent electrical performance with active product status. Selection between these options depends on packaging requirements and supplier availability.

Parametric Equivalents (74LVC1G74 Series):

The 74LVC1G74 series parts are parametric equivalents with identical core electrical specifications. These single-element flip-flops function identically to the dual-element 74LVC2G74 when only one flip-flop is required. All listed 74LVC1G74 variants maintain 200 MHz clock frequency, 4.1ns propagation delay, and 1.65V to 5.5V supply voltage operation.

74LVC1G74GT-Q100X includes AEC-Q100 automotive qualification, suitable for automotive applications requiring grade certification.

SN74LVC1G74DQER from Texas Instruments provides an alternative source with marginally higher propagation delay (4.4ns) and lower quiescent current (10 µA).

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a 74LVC1G74 part to replace the 74LVC2G74GF,115?

A: Yes, if your circuit design uses only one flip-flop element. The 74LVC1G74 series provides identical electrical performance for single-element applications. If your design requires dual flip-flops, use 74LVC2G74 direct substitutes.

Q: What is the difference between 74LVC2G74GS,115 and 74LVC2G74GN,115?

A: Both parts are electrically identical with matching specifications. The primary difference is packaging format: GS,115 is supplied in Tape & Reel, while GN,115 is supplied in Tape & Reel as well. Supplier device package dimensions vary slightly (1.35x1 versus 1.2x1).

Q: Is the SN74LVC1G74DQER from Texas Instruments a suitable replacement?

A: Yes, for single flip-flop applications. The part meets all electrical requirements with 200 MHz clock frequency and 1.65V to 5.5V supply voltage. Propagation delay is marginally higher at 4.4ns versus 4.1ns. Quiescent current is lower at 10 µA.

Q: Why is the 74LVC2G74GF,115 marked as obsolete?

A: The part has been discontinued by the manufacturer. Active equivalent parts from the same 74LVC2G74 series are available as direct replacements with identical specifications and continued production support.

Q: What packaging considerations apply to these substitutes?

A: All substitutes use the 8-XFDFN surface mount package. Packaging formats (Tape & Reel, Bulk, Cut Tape) affect procurement and assembly processes but do not impact electrical performance or board-level compatibility.

Q: Can I mix different manufacturers in my design?

A: Yes. All listed substitutes maintain identical electrical specifications, supply voltage range, clock frequency, and propagation delay. Cross-manufacturer substitution is electrically valid within the same package type.
