Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVTH574NSR is determined by strict equivalence across the following critical parameters: D-Type flip-flop architecture with 8-bit configuration, 150 MHz clock frequency capability, 4.5ns maximum propagation delay at 3.3V with 50pF load, tri-state non-inverted output configuration, 2.7V to 3.6V supply voltage range, 32mA/64mA output current specifications, -40°C to 85°C operating temperature range, 20-SOIC surface mount packaging, and Active product status with RoHS3 compliance. Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVTH374NSR qualifies as a direct parametric equivalent to the SN74LVTH574NSR based on complete alignment across all specified electrical and mechanical parameters. Both parts maintain Active product status from Texas Instruments, carry identical RoHS3 compliance certification, and share equivalent MSL ratings. Selection between these parts depends on design-specific requirements not defined within the provided parameter set. Both parts are suitable for applications requiring 8-bit D-Type flip-flop functionality within the specified voltage, frequency, and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: What defines a substitute part for the SN74LVTH574NSR? A: A substitute part must match all critical parameters: 8-bit D-Type flip-flop configuration, 150 MHz clock frequency, 4.5ns propagation delay at 3.3V with 50pF load, tri-state non-inverted outputs, 2.7V to 3.6V supply voltage, 32mA/64mA output current, -40°C to 85°C operating temperature, 20-SOIC surface mount package, and Active product status with RoHS3 compliance.

Q: Are the SN74LVTH574NSR and SN74LVTH374NSR pin-compatible? A: Both parts use identical 20-SOIC (0.209", 5.30mm Width) surface mount packaging. Pin compatibility is determined by the specific application circuit design and functional requirements.

Q: Can these parts be used interchangeably in production? A: Parts meeting all specified parameters are electrically and mechanically equivalent. Production substitution decisions must account for design validation, supply chain considerations, and any application-specific requirements beyond the provided parameter set.

Q: What is the significance of the RoHS3 compliance rating? A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations, confirming absence of restricted materials within specified thresholds. Both the main part and substitute maintain this certification status.

Q: Does MSL rating 1 (Unlimited) affect substitution eligibility? A: MSL rating 1 (Unlimited) indicates no moisture sensitivity restrictions during storage and handling. Both parts share this rating, eliminating moisture sensitivity as a differentiation factor in substitution decisions.
