MPC905EF Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The MPC905EF is a Clock Fanout Buffer (Distribution) IC manufactured by Renesas Electronics Corporation, designed for 1:6 clock distribution at frequencies up to 100 MHz. This component features LVCMOS output and operates across a 3V to 3.6V supply voltage range in a 16-SOIC surface mount package.

The MPC905EF is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MPC905EF is determined by strict alignment of the following electrical and mechanical parameters:

• Fanout Configuration: 1:6 input-to-output ratio
• Maximum Frequency: 100 MHz operation capability
• Package Type: 16-SOIC surface mount form factor
• Input Interface: Crystal input compatibility
• Output Logic Family: LVCMOS or compatible logic levels
• Supply Voltage Range: Compatibility with 3V to 3.6V operation
• Operating Temperature Range: 0°C to 70°C
• Moisture Sensitivity: MSL 3 classification

The substitute part 83905AMLF meets these core substitution criteria while maintaining functional equivalence for clock distribution applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MPC905EF and 83905AMLF are obsolete components from Renesas Electronics Corporation. Selection between these parts should be based on the following factors:

Supply Voltage Compatibility: The 83905AMLF operates across a wider supply voltage range (1.6V to 3.465V) compared to the MPC905EF (3V to 3.6V). Applications requiring operation at the MPC905EF's specified 3V to 3.6V range are compatible with the 83905AMLF.

Output Logic Flexibility: The 83905AMLF supports both LVCMOS and LVTTL output logic families, whereas the MPC905EF is specified for LVCMOS only. This provides additional flexibility in the 83905AMLF for systems requiring LVTTL compatibility.

Regulatory Compliance: Both parts maintain REACH Unaffected status and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory standing.

Packaging and Thermal Characteristics: Both components share identical 16-SOIC packaging, MSL 3 moisture sensitivity rating, and operating temperature range, ensuring mechanical and thermal interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 83905AMLF directly replace the MPC905EF in existing designs?

A: Yes, the 83905AMLF is a direct functional substitute for the MPC905EF. Both components share identical 1:6 fanout configuration, 100 MHz maximum frequency, 16-SOIC package, and operating temperature range. The 83905AMLF's wider supply voltage range and dual output logic support (LVCMOS and LVTTL) provide additional design flexibility without compromising compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range and output logic options. The 83905AMLF operates from 1.6V to 3.465V (versus 3V to 3.6V for the MPC905EF) and supports both LVCMOS and LVTTL outputs (versus LVCMOS only for the MPC905EF). Both parts are functionally equivalent for 1:6 clock distribution at 100 MHz.

Q: Are there any package or pinout differences?

A: No. Both the MPC905EF and 83905AMLF use the identical 16-SOIC (0.154", 3.90mm Width) package with the same pinout configuration, ensuring direct mechanical and electrical interchangeability.

Q: What is the significance of the obsolete product status?

A: Both parts are classified as obsolete by Renesas Electronics Corporation. This status indicates that these components are no longer in active production. Availability is limited to existing inventory. For new designs or long-term supply requirements, consultation with component distributors regarding inventory levels and alternative current-generation clock distribution solutions is recommended.

Q: Are there regulatory or compliance considerations for substitution?

A: Both parts maintain identical REACH Unaffected status, ECCN (EAR99), and HTSUS (8542.39.0001) classifications. No additional regulatory review is required for substitution between these parts.
