ICS574MT Equivalent & Substitute Parts

Part Overview

The ICS574MT is a Fanout Buffer (Distribution) with Zero Delay Buffer functionality manufactured by Renesas Electronics Corporation. This 8-SOIC surface mount integrated circuit operates at a maximum frequency of 160MHz and features a 1:4 input-to-output ratio with integrated PLL capability. The device is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the ICS574MT is determined by strict equivalence across the following critical parameters:

• Functional Type: Fanout Buffer (Distribution) with Zero Delay Buffer capability
• Frequency Rating: 160MHz maximum operating frequency
• Input/Output Configuration: CMOS input and CMOS output
• Circuit Count and Ratio: Single circuit with 1:4 input-to-output ratio
• PLL Functionality: Integrated Phase-Locked Loop
• Supply Voltage Range: 3V to 5.5V operation
• Operating Temperature Range: 0°C to 70°C
• Package Type: 8-SOIC (0.154", 3.90mm Width) surface mount
• Electrical Characteristics: Divider/Multiplier capability (No/Yes)

The substitute part 574MLFT meets all these parameters identically, establishing it as a parametric equivalent. Differences in packaging format (Cut Tape & Digi-Reel versus standard packaging) and RoHS compliance status do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The 574MLFT serves as a direct parametric equivalent to the ICS574MT across all functional and electrical specifications. Both devices are classified as obsolete products from Renesas Electronics Corporation.

A key distinction exists in regulatory compliance: the ICS574MT is RoHS non-compliant, while the 574MLFT achieves ROHS3 compliance. For applications subject to RoHS directives or environmental regulations, the 574MLFT is the appropriate selection. For legacy systems or applications without RoHS requirements, either part satisfies the electrical and functional specifications identically.

Both parts maintain identical MSL ratings (1 - Unlimited), supply voltage ranges (3V to 5.5V), and operating temperature specifications (0°C to 70°C), ensuring interchangeability in PCB assembly and thermal management contexts.

Frequently Asked Questions (FAQ)

Q: Can the 574MLFT replace the ICS574MT in existing designs?

A: Yes. The 574MLFT is a parametric equivalent with identical electrical specifications, frequency rating, input/output configuration, and package type. Functional substitution is direct.

Q: What is the difference between ICS574MT and 574MLFT?

A: The primary difference is RoHS compliance status. The ICS574MT is RoHS non-compliant, while the 574MLFT is ROHS3 compliant. All electrical and functional parameters are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The 574MLFT is supplied in Cut Tape & Digi-Reel format, while the ICS574MT uses standard packaging. This does not affect electrical compatibility or PCB assembly.

Q: Why is the ICS574MT classified as obsolete?

A: Product status reflects manufacturer discontinuation. The 574MLFT is also obsolete, indicating both parts are no longer in active production. Existing inventory may be available through authorized distributors.

Q: What are the critical parameters for substitution?

A: Substitution requires equivalence in frequency rating (160MHz), input/output type (CMOS/CMOS), circuit ratio (1:4), PLL functionality, supply voltage range (3V to 5.5V), operating temperature (0°C to 70°C), and package type (8-SOIC surface mount).

Q: Can these parts be used in new designs?

A: Both the ICS574MT and 574MLFT are obsolete products. New designs should evaluate current-generation Renesas fanout buffer offerings. For legacy system support or replacement applications, these parts remain functionally viable within their specified operating parameters.
