Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC574AQ20-13 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Core Substitution Criteria:

• D-Type flip-flop architecture with 8-bit configuration
• Positive edge trigger operation
• Supply voltage range: 1.65V ~ 3.6V
• Non-inverted output type
• Surface mount packaging in 20-pin VFQFN format
• Operating temperature range: -40°C ~ 125°C
• RoHS3 compliance and MSL Level 1 rating

Parametric Equivalent: The 74LVC374AQ20-13 maintains identical electrical specifications and package configuration, with minor variations in propagation delay and load capacitance specifications that remain within acceptable operational margins for D-Type flip-flop applications.

Direct Manufacturer Substitute: The 74LVC574ABQ,115 from Nexperia USA Inc. operates within the same 74LVC series with enhanced clock frequency capability (200 MHz vs. 125 MHz) and tri-state output capability, while maintaining core voltage, temperature, and package compatibility.
