74LVC16374APFG8 Equivalent & Substitute Parts

Part Overview

The 74LVC16374APFG8 is a dual 8-bit D-type flip-flop logic IC manufactured by Renesas Electronics Corporation in a 48-TFSOP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates as a standard positive-edge-triggered flip-flop with tri-state, non-inverted outputs, suitable for digital logic applications requiring synchronous data storage and transfer.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC16374ADGVR (Texas Instruments) is the primary substitute for the 74LVC16374APFG8. This part maintains identical package dimensions (48-TFSOP 0.173", 4.40mm), matching propagation delay (4.5ns @ 3.3V, 50pF), and clock frequency (150 MHz). The part is active in production with ROHS3 compliance and extended supply voltage range (1.65V ~ 3.6V). Operating temperature range matches the original (-40°C ~ 85°C). This substitute provides direct pin-compatible replacement with no design modifications required.

74LVC16374ADGG,118 (Nexperia USA Inc.) is a secondary substitute option. While functionally equivalent, this part features a different package footprint (48-TFSOP 0.240", 6.10mm width) requiring PCB layout modifications. The part offers superior clock frequency (300 MHz) and extended operating temperature range (-40°C ~ 125°C), with ROHS3 compliance. Selection of this substitute is appropriate only when PCB redesign is feasible or when enhanced thermal performance is required.

Both substitutes are active production parts with established supply availability and compliance certifications, addressing the obsolescence of the original Renesas component.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC16374ADGVR directly replace the 74LVC16374APFG8 without PCB modifications?

A: Yes. The SN74LVC16374ADGVR maintains identical 48-TFSOP package dimensions (0.173", 4.40mm width), pin configuration, and electrical specifications. Direct substitution on existing PCBs is possible without layout changes.

Q: What is the primary difference between the two substitute parts?

A: The SN74LVC16374ADGVR (Texas Instruments) maintains the original package footprint (0.173" width), while the 74LVC16374ADGG,118 (Nexperia) uses a wider package (0.240" width). The Nexperia part also offers higher clock frequency (300 MHz vs. 150 MHz) and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C).

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the SN74LVC16374ADGVR and 74LVC16374ADGG,118 are ROHS3 compliant. The original 74LVC16374APFG8 RoHS status was not specified in available documentation.

Q: What is the voltage supply compatibility of these substitutes?

A: Both substitutes support extended voltage ranges (1.65V ~ 3.6V) compared to the original part (2.7V ~ 3.6V). This provides greater design flexibility for low-voltage applications while maintaining full compatibility with the original 2.7V ~ 3.6V operating range.

Q: How do the quiescent current specifications compare?

A: The original 74LVC16374APFG8 specifies 10 µA quiescent current, while both substitutes specify 20 µA. This difference is within acceptable tolerance for most applications but should be evaluated for power-critical designs.

Q: Are there any temperature range limitations when substituting?

A: The SN74LVC16374ADGVR matches the original operating temperature range (-40°C ~ 85°C). The 74LVC16374ADGG,118 extends to -40°C ~ 125°C, providing additional thermal margin. Selection depends on application temperature requirements.

Q: What is the moisture sensitivity level for these parts?

A: All three parts, including both substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
