SN74LVTH374IPWREP Equivalent & Substitute Parts

Part Overview

The SN74LVTH374IPWREP is a D-type flip-flop logic integrated circuit manufactured by Texas Instruments, designed for 8-bit data storage and transfer applications. This device operates at supply voltages between 2.7V and 3.6V with a maximum clock frequency of 150 MHz, making it suitable for low-voltage digital logic systems. The part is currently in active production status with 1046 units in stock. Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required, or when sourcing from multiple manufacturers is needed for supply chain resilience.

The substitute parts listed maintain all critical electrical and mechanical parameters within the specified tolerances, ensuring direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments SN74LVTH374PWR is the primary parametric equivalent, offering identical electrical specifications and active product status. This part maintains full compatibility with the original SN74LVTH374IPWREP and is recommended for direct substitution when the IPWREP variant is unavailable. Higher inventory availability (3118 units) supports consistent supply.

Texas Instruments SN74LVTH574PWR provides equivalent electrical performance with the highest inventory level (5400 units). This part maintains all critical parameters and active product status, making it suitable for applications requiring maximum supply availability.

onsemi 74LVT574MTCX and 74LVTH574MTCX are manufacturer-recommended alternatives from onsemi. Both parts meet all electrical and mechanical specifications with propagation delay of 4.6ns, which remains within acceptable tolerance. However, both parts carry Last Time Buy status, indicating discontinued production. These options are suitable only when long-term supply is not a requirement or when existing inventory is available for immediate use.

For new designs and applications requiring long-term availability, Texas Instruments parts with Active status are preferred. For supply chain diversification or when onsemi inventory is available, the onsemi alternatives provide equivalent functionality within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can SN74LVTH374PWR directly replace SN74LVTH374IPWREP?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, package type (20-TSSOP), and compliance certifications. The difference lies in packaging format (tape & reel variant designation), not functional performance. Direct substitution is supported without circuit modification.

Q: What is the difference between the 74LVTH374 and 74LVTH574 series?

A: Both are 8-bit D-type flip-flops with identical electrical parameters, supply voltage, clock frequency, and output characteristics. The primary distinction is in the base product number designation. Both are functionally equivalent for this application and meet all substitution criteria.

Q: Why do onsemi parts show Last Time Buy status?

A: Last Time Buy status indicates that the manufacturer has discontinued production and existing inventory represents the final available supply. These parts remain fully functional and compliant with all specifications. Selection of Last Time Buy parts should be based on immediate availability requirements and long-term supply planning.

Q: Are there any differences in propagation delay between the Texas Instruments and onsemi parts?

A: Texas Instruments parts specify 4.5ns maximum propagation delay, while onsemi parts specify 4.6ns. Both values are within acceptable tolerance for the 150 MHz operating frequency and do not affect functional compatibility in standard applications.

Q: Can I use these parts interchangeably in my circuit?

A: Yes, all listed substitute parts maintain identical package footprints (20-TSSOP), pin configurations, electrical specifications, and operating ranges. Interchangeability is supported at the circuit board level without design changes.

Q: What packaging format differences exist between these part numbers?

A: SN74LVTH374IPWREP and SN74LVTH374PWR are supplied in Tape & Reel (TR) format. The onsemi parts (74LVT574MTCX and 74LVTH574MTCX) are supplied in Cut Tape (CT) & Digi-Reel format. Both packaging formats are compatible with standard surface mount assembly equipment and provide equivalent component protection and handling characteristics.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing processes and environmental regulations.
