Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC374ABQ,115 are qualified based on the following critical parameters that determine functional and electrical compatibility:

• Logic Function: D-type flip-flop with 1 element and 8 bits per element
• Trigger Mechanism: Positive edge-triggered operation
• Output Configuration: Non-inverted logic levels
• Supply Voltage Range: 1.65V to 3.6V compatibility
• Operating Temperature Range: -40°C to 125°C
• Package Type: 20-pin VFQFN with exposed pad
• Mounting Technology: Surface mount
• Series Classification: 74LVC logic family
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The 74LVC374AQ20-13 manufactured by Diodes Incorporated meets all substitution criteria within these parameters. Variations in clock frequency and propagation delay do not preclude substitution when the substitute part meets or exceeds the minimum performance requirements of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the 74LVC374ABQ,115 and 74LVC374AQ20-13 are active-status products with full ROHS3 compliance and REACH unaffected designation, meeting current regulatory requirements for electronic component manufacturing and use. Selection between these parts should be based on:

• Supply Chain Availability: The 74LVC374AQ20-13 currently maintains higher inventory levels (5100 pcs vs. 978 pcs), supporting extended lead time requirements and volume production schedules.
• Performance Margin: The 74LVC374AQ20-13 delivers faster propagation delay (6.8 ns vs. 7 ns), providing additional timing margin in clock-synchronous applications.
• Manufacturer Preference: Design specifications may mandate a specific manufacturer. Both parts are qualified for equivalent substitution when manufacturer flexibility is permitted.
• Package Compatibility: Both parts use identical 20-VFQFN exposed pad packaging, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC374AQ20-13 directly replace the 74LVC374ABQ,115 on existing PCBs?

A: Yes. Both parts use the same 20-VFQFN exposed pad package with identical pin assignments and electrical characteristics within the specified operating ranges. No PCB layout modifications are required.

Q: What is the difference between the Tri-State output specification on the main part versus the Non-Inverted specification on the substitute?

A: The 74LVC374ABQ,115 explicitly lists Tri-State and Non-Inverted output types. The 74LVC374AQ20-13 specifies Non-Inverted output. Both parts implement the same D-type flip-flop logic function with non-inverted outputs. The tri-state capability is inherent to the 74LVC374 architecture across both manufacturers.

Q: Are there timing differences that affect circuit performance?

A: The 74LVC374AQ20-13 operates at a lower maximum clock frequency (125 MHz vs. 150 MHz) and exhibits faster propagation delay (6.8 ns vs. 7 ns). For applications operating below 125 MHz, the substitute part meets all timing requirements. Applications requiring operation above 125 MHz must use the 74LVC374ABQ,115.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 74LVC374ABQ,115 and 74LVC374AQ20-13 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for component procurement and use.

Q: What supply voltage range is supported by both parts?

A: Both parts operate across the identical supply voltage range of 1.65V to 3.6V, supporting low-voltage and standard logic applications without modification.
