Engineering Selection Recommendations

Primary Recommendation - Parametric Equivalent:

The 74LVCH16374APVG (IDT, Integrated Device Technology Inc) is the direct parametric equivalent. It maintains identical electrical specifications including 150 MHz clock frequency, 4.5ns propagation delay at 3.3V with 50pF load, 24mA output drive, and 10 µA quiescent current. The supply voltage range is 2.7V to 3.6V, which overlaps the original 2.3V to 3.6V specification. This part is active and available in bulk packaging with 12,472 units in stock.

Active Alternatives - Same Package (48-BSSOP):

For designs requiring active product status with enhanced specifications, the following Texas Instruments parts are recommended:

SN74LVC16374ADL, SN74LVC16374ADLR, SN74LVC16374DL, and SN74LVCH16374ADL all maintain the 48-BSSOP package footprint. These parts feature extended supply voltage ranges (1.65V to 3.6V), ROHS3 compliance, and active product status. SN74LVC16374ADLR and SN74LVCH16374ADLR offer the highest inventory availability (41,597 and 2,786 units respectively) and are packaged in Tape & Reel format suitable for automated assembly.

SN74LVCH16374ADL and SN74LVCH16374ADLR extend the operating temperature range to -40°C to 125°C, providing enhanced thermal performance for demanding applications.

Package Variant Alternative:

The 74LVC16374ADGG,118 (Nexperia) offers superior performance with 300 MHz clock frequency and 5.4ns propagation delay, but uses the 48-TFSOP package (0.240", 6.10mm width). This package variant requires PCB layout modification and is suitable only for new designs where footprint changes are acceptable.

Not Recommended:

CY74FCT16374CTPVC (Texas Instruments) operates at 4.5V to 5.5V supply voltage, incompatible with the 3.3V logic domain of the original part. Additionally, it is obsolete with significantly higher quiescent current (500 µA) and is not suitable as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC16374DLR as a direct replacement for 74LVC16374APVG?

A: SN74LVC16374DLR is functionally compatible but with performance trade-offs. It maintains the same 48-BSSOP package and dual 8-bit D-type configuration. However, the clock frequency is reduced to 100 MHz and propagation delay increases to 7.5ns at 3.3V with 50pF load, compared to the original 150 MHz and 4.5ns. The supply voltage range is 2.7V to 3.6V. This part is suitable for applications where the reduced speed is acceptable.

Q: What is the difference between 74LVCH16374APVG and SN74LVCH16374ADL?

A: Both are 74LVCH series parts with identical electrical performance (150 MHz, 4.5ns propagation delay). The primary differences are manufacturer (IDT versus Texas Instruments), packaging format (bulk versus tube), and operating temperature range. SN74LVCH16374ADL extends to -40°C to 125°C, while 74LVCH16374APVG operates to -40°C to 85°C. Both are active products with ROHS3 compliance.

Q: Why does 74LVC16374ADGG,118 have different package dimensions?

A: The 74LVC16374ADGG,118 uses the 48-TFSOP package (0.240", 6.10mm width) instead of the 48-BSSOP package (0.295", 7.50mm width). This is a narrower package variant that requires different PCB footprint and layout. While electrically compatible, physical substitution requires PCB redesign and is not recommended for drop-in replacement scenarios.

Q: Is the 74LVCH16374APVG available in tape and reel packaging?

A: The provided data specifies 74LVCH16374APVG in bulk packaging only. For tape and reel packaging of equivalent 74LVCH series parts, SN74LVCH16374ADLR (Texas Instruments) is available with 2,786 units in stock and identical electrical specifications.

Q: What is the minimum supply voltage for the substitute parts?

A: The original 74LVC16374APVG operates at 2.3V minimum. Most active substitutes (SN74LVC16374ADL, SN74LVC16374ADLR, SN74LVCH16374ADL, SN74LVCH16374ADLR) support 1.65V minimum, providing enhanced low-voltage operation. The 74LVCH16374APVG operates at 2.7V minimum. For applications requiring 2.3V operation, verify compatibility with the specific substitute selected.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original 74LVC16374APVG (obsolete) does not specify RoHS status. CY74FCT16374CTPVC is also ROHS3 compliant but is obsolete and not recommended due to incompatible supply voltage requirements.
