ICS574M Equivalent & Substitute Parts

Part Overview

The ICS574M 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 product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS574M is determined by strict equivalence across the following critical parameters:

• Functional type: Fanout Buffer with Zero Delay Buffer capability
• Maximum frequency: 160MHz operation
• Input/Output configuration: CMOS/CMOS with 1:4 ratio
• PLL integration: Required
• Package type: 8-SOIC form factor
• Supply voltage range: 3V ~ 5.5V compatibility
• Mounting method: Surface Mount

The substitute part 574MLF meets all these criteria while offering improved RoHS3 compliance status. Both parts share identical electrical specifications and mechanical packaging, enabling direct substitution in applications where the ICS574M is specified.

Parameter Comparison

Engineering Selection Recommendations

The 574MLF serves as the direct substitute for the ICS574M based on complete electrical and mechanical equivalence. The primary distinction between these parts is regulatory compliance: the 574MLF achieves RoHS3 compliance while the ICS574M does not. For applications subject to RoHS requirements or environmental regulations, the 574MLF is the appropriate selection. Both parts maintain identical functional specifications, package geometry, and thermal operating ranges, ensuring pin-for-pin compatibility in existing circuit designs. The MSL rating of 1 (Unlimited) for both parts indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the 574MLF directly replace the ICS574M in existing designs? A: Yes. The 574MLF is electrically and mechanically equivalent to the ICS574M. Both parts feature identical frequency specifications (160MHz), supply voltage ranges (3V ~ 5.5V), package geometry (8-SOIC), and functional characteristics (1:4 fanout buffer with PLL). Direct substitution is supported without circuit modification.

Q: What is the primary difference between ICS574M and 574MLF? A: The 574MLF achieves RoHS3 compliance, while the ICS574M is RoHS non-compliant. All other electrical, mechanical, and thermal specifications 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 ICS574M is supplied in standard packaging, while the 574MLF is supplied in tube packaging. The physical component dimensions and pin configuration remain identical.

Q: What does the 1:4 ratio specification mean? A: The 1:4 input-to-output ratio indicates that one input signal is distributed to four output channels. This fanout buffer configuration enables clock distribution from a single source to multiple destinations while maintaining zero delay propagation.

Q: Are moisture sensitivity considerations important for these parts? A: Both parts carry an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity. Standard handling and storage procedures are sufficient; specialized dry-pack storage is not required.

Q: Can these parts operate at frequencies below 160MHz? A: Yes. The 160MHz specification represents the maximum operating frequency. Both parts function at lower frequencies within the specified supply voltage range of 3V ~ 5.5V and operating temperature range of 0°C ~ 70°C.
