Parameter Comparison

Engineering Selection Recommendations

74LVC1G74DC,125 is a direct parametric equivalent with identical electrical specifications and performance characteristics. The primary difference is packaging format availability (Cut Tape & Digi-Reel®). This part is suitable for applications requiring standard commercial-grade components with flexible packaging options.

74LVC1G74DC-Q100H is qualified to AEC-Q100 automotive standards and carries automotive-grade designation. All electrical and timing parameters remain identical to the main part. This variant is required for automotive applications subject to automotive qualification requirements.

74LVC2G74DC,125 maintains all critical electrical parameters and timing specifications. The quiescent current specification is 40 µA compared to 4 µA in the main part. This part is suitable for applications where the higher quiescent current is acceptable and where the 74LVC2G74 base product number variant is preferred.

All substitute parts maintain Active product status, ROHS3 compliance, and MSL 1 rating, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can 74LVC1G74DC,125 be used as a direct replacement for 74LVC1G74DC/S470,1?

A: Yes. Both parts are parametrically equivalent with identical electrical specifications, timing characteristics, and package dimensions. The difference is limited to packaging format. 74LVC1G74DC,125 offers Cut Tape and Digi-Reel® options, while 74LVC1G74DC/S470,1 is supplied in Digi-Reel® format.

Q: When should 74LVC1G74DC-Q100H be selected?

A: 74LVC1G74DC-Q100H is required for automotive applications requiring AEC-Q100 qualification. All electrical and timing parameters are identical to the standard part. Selection is driven by application requirements and automotive compliance mandates, not performance differences.

Q: What is the significance of the quiescent current difference in 74LVC2G74DC,125?

A: The 74LVC2G74DC,125 has a quiescent current specification of 40 µA compared to 4 µA in the main part. This represents a 10-fold increase in standby power consumption. Selection should be based on application power budget requirements and whether the higher quiescent current is acceptable for the intended use case.

Q: Are all substitute parts available in the same 8-VFSOP package?

A: Yes. All substitute parts use the 8-VFSOP (0.091", 2.30mm Width) package with Surface Mount mounting type. Package dimensions and footprints are identical across all variants.

Q: Do all parts meet the same compliance and regulatory standards?

A: Yes. All parts listed are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain Active product status. The 74LVC1G74DC-Q100H additionally carries AEC-Q100 automotive qualification.
