74LVTH574D,112 Equivalent & Substitute Parts

Part Overview

The 74LVTH574D,112 is a D-type flip-flop logic integrated circuit manufactured by NXP USA Inc., featuring 1 element with 8-bit positive edge triggering in a 20-SOIC surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The 74LVTH574 series operates at 150 MHz clock frequency with tri-state, non-inverted outputs, designed for low-voltage CMOS applications with supply voltage range of 2.7V to 3.6V. Current product status transitions require identification of active alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 74LVTH574D,112 is determined by strict equivalence across the following critical parameters:

• Functional equivalence: D-type flip-flop, 1 element, 8-bit configuration with positive edge triggering
• Output characteristics: Tri-state, non-inverted output type
• Electrical specifications: Clock frequency 150 MHz, supply voltage 2.7V ~ 3.6V, output current ratings 32 mA / 64 mA
• Thermal performance: Operating temperature range -40°C ~ 85°C
• Package compatibility: 20-SOIC (0.295", 7.50mm Width) surface mount package
• Compliance: ROHS3 compliant, MSL Level 1

Substitute parts are grouped into three categories based on manufacturer designation and product status:

1. Direct Manufacturer Equivalent: SN74LVT574DWR (Texas Instruments) - Active product status, identical parametric performance
2. MFR Recommended Equivalents: SN74LVTH574DW and SN74LVTH574DWR (Texas Instruments) - Active product status, same base series with improved propagation delay performance
3. Parametric Equivalent: SN74LVT574DW (Texas Instruments) - Active product status, identical electrical specifications

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with Texas Instruments, ensuring long-term availability and manufacturing support compared to the obsolete NXP 74LVTH574D,112.

SN74LVTH574DWR (Tape & Reel packaging) and SN74LVTH574DW (Tube packaging) are manufacturer-recommended equivalents within the same 74LVTH series, offering improved propagation delay performance of 4.5 ns at 3.3V and 50 pF load compared to the original 5.9 ns specification. These parts feature reduced input capacitance of 3 pF, providing enhanced signal integrity in high-speed applications.

SN74LVT574DWR and SN74LVT574DW are direct parametric equivalents from the 74LVT series, maintaining identical electrical specifications including 5.9 ns propagation delay and 4 pF input capacitance. These alternatives provide functional compatibility with identical output current ratings and supply voltage specifications.

All substitute parts comply with ROHS3 requirements and maintain MSL Level 1 classification, supporting standard manufacturing and storage conditions without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can SN74LVTH574DWR replace 74LVTH574D,112 in existing designs?

A: Yes. SN74LVTH574DWR is a direct manufacturer-recommended equivalent with identical functional specifications, electrical parameters, and 20-SOIC package compatibility. The improved propagation delay of 4.5 ns provides enhanced performance margin.

Q: What is the difference between 74LVTH and 74LVT series substitutes?

A: Both series maintain identical D-type flip-flop functionality, output characteristics, and supply voltage specifications. The 74LVT series (SN74LVT574DWR, SN74LVT574DW) exhibits 5.9 ns propagation delay with 4 pF input capacitance, while the 74LVTH series (SN74LVTH574DW, SN74LVTH574DWR) offers improved 4.5 ns propagation delay with 3 pF input capacitance.

Q: Does packaging type affect electrical performance?

A: No. Tape & Reel (TR) and Tube packaging options provide identical electrical specifications and functional performance. Packaging selection is determined by procurement and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL Level 1 classification, meeting environmental and manufacturing standards equivalent to the original part.

Q: What is the inventory status of substitute parts?

A: SN74LVTH574DWR maintains the highest inventory availability at 91,697 pieces. SN74LVTH574DW and SN74LVT574DWR each maintain 1,240 and 2,200 pieces respectively, supporting immediate procurement requirements.
