Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC16374APFG is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Type: D-Type Flip Flop (2 elements, 8 bits per element)
• Output Type: Tri-State, Non-Inverted
• Trigger Type: Positive Edge
• Clock Frequency: 150 MHz minimum
• Max Propagation Delay: 4.5ns @ 3.3V, 50pF or better

Electrical Parameters:

• Output Current: 24mA (High and Low)
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package: 48-TFSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Supply Voltage Compatibility: The substitute part must operate within or encompass the original supply voltage range of 2.7V ~ 3.6V. A wider supply voltage range is acceptable provided the lower bound does not exceed 2.7V and the upper bound meets or exceeds 3.6V.

The SN74LVC16374ADGVR from Texas Instruments meets all functional and electrical equivalence criteria while maintaining full pin and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC16374ADGVR from Texas Instruments is the direct functional equivalent for the obsolete 74LVC16374APFG. Selection of this substitute is supported by the following factors:

Product Status: The Texas Instruments part maintains active product status, ensuring continued availability and manufacturing support. The Renesas part is classified as obsolete, making the Texas Instruments alternative the appropriate choice for new designs and ongoing procurement.

Compliance and Certifications: Both parts carry identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The Texas Instruments part includes RoHS3 compliance certification, providing additional environmental compliance assurance.

Electrical Performance: The substitute part meets or exceeds all specified electrical parameters. The wider supply voltage range (1.65V ~ 3.6V) provides enhanced flexibility for multi-voltage system designs while maintaining full compatibility with the original 2.7V ~ 3.6V specification.

Inventory Availability: The Texas Instruments part is available in significantly higher quantities (3000 Pcs) compared to the Renesas part (921 Pcs), supporting both immediate procurement needs and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC16374ADGVR be used as a direct replacement for the 74LVC16374APFG?

A: Yes. Both parts are functionally equivalent dual 8-bit D-type flip-flops with tri-state, non-inverted outputs in the 48-TFSOP package. All critical electrical parameters, including clock frequency, propagation delay, output current, and operating temperature range, are identical or compatible. Pin configuration and package dimensions are equivalent, enabling direct PCB substitution.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Renesas versus Texas Instruments) and product status (obsolete versus active). The Texas Instruments part features a wider supply voltage range (1.65V ~ 3.6V versus 2.7V ~ 3.6V), slightly higher quiescent current (20 µA versus 10 µA), and marginally higher input capacitance (5 pF versus 4.5 pF). These differences do not affect functional compatibility in applications designed for the original part.

Q: Are there any package or pinout differences?

A: No. Both parts use the identical 48-TFSOP (0.173", 4.40mm Width) surface mount package with equivalent pinout. No PCB layout modifications are required for substitution.

Q: Why is the original part listed as obsolete?

A: The 74LVC16374APFG from Renesas Electronics has reached end-of-life status. The Texas Instruments SN74LVC16374ADGVR remains in active production and is the recommended alternative for new designs and replacement procurement.

Q: Does the higher quiescent current of the substitute part affect system performance?

A: The difference in quiescent current (20 µA versus 10 µA) is negligible in most applications. This parameter becomes relevant only in ultra-low-power designs where every microampere of standby current is critical. For standard logic applications, this difference is not operationally significant.

Q: Is the substitute part RoHS compliant?

A: Yes. The SN74LVC16374ADGVR carries RoHS3 compliance certification. The original Renesas part does not specify RoHS status in the provided data.
