MAX9316EWP+ Equivalent & Substitute Parts

Part Overview

The MAX9316EWP+ is a clock fanout buffer (distribution) multiplexer IC manufactured by Analog Devices Inc./Maxim Integrated. This device functions as a 2:5 clock distribution buffer with a maximum frequency rating of 1.5 GHz, supporting differential input and output configurations with HSTL, LVECL, and LVPECL signal levels. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9316EWP+ is determined by strict equivalence across the following critical parameters:

• Functional Architecture: 2:5 input-to-output ratio with differential input and output capability
• Signal Level Support: HSTL, LVECL, and LVPECL compatibility for both input and output
• Frequency Rating: 1.5 GHz maximum operating frequency
• Supply Voltage Range: Compatibility within the specified voltage envelope
• Operating Temperature Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Moisture Sensitivity: MSL 1 rating

The MAX9315EUP+ qualifies as a direct substitute based on identical performance specifications across all critical parameters. The primary distinction is the package format change from 20-SOIC to 20-TSSOP and an expanded lower supply voltage limit (2.25V vs. 3V), which represents an enhancement rather than a limitation.

Parameter Comparison

Engineering Selection Recommendations

The MAX9315EUP+ is the direct functional equivalent of the MAX9316EWP+ and is recommended for new designs and production transitions due to its active product status. Both devices maintain identical electrical specifications, signal level support, frequency ratings, and regulatory compliance certifications.

The primary design consideration is the package transition from 20-SOIC to 20-TSSOP. This change requires PCB layout modification to accommodate the different footprint dimensions (0.295" vs. 0.173" width). The TSSOP package offers a smaller form factor, which may provide space optimization benefits in board-constrained applications.

The expanded supply voltage range of the MAX9315EUP+ (2.25V minimum vs. 3V minimum) provides additional operational flexibility and does not introduce any compatibility constraints for systems designed to the original 3V ~ 3.8V specification.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the MAX9315EUP+ be used as a direct pin-for-pin replacement for the MAX9316EWP+?

A: The MAX9315EUP+ is functionally equivalent but not pin-for-pin compatible due to package differences. The MAX9316EWP+ uses a 20-SOIC package while the MAX9315EUP+ uses a 20-TSSOP package. PCB layout and footprint redesign is required.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both devices share identical input-to-output ratios (2:5), differential signal support, signal level compatibility (HSTL, LVECL, LVPECL), maximum frequency (1.5 GHz), operating temperature range (-40°C to 85°C), and regulatory compliance status.

Q: What is the significance of the expanded supply voltage range in the MAX9315EUP+?

A: The MAX9315EUP+ supports a lower minimum supply voltage (2.25V vs. 3V). This expansion does not affect compatibility with systems designed for the original 3V ~ 3.8V range and provides additional operational margin for lower-voltage applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the MAX9316EWP+ and MAX9315EUP+ are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the MAX9316EWP+ classified as obsolete?

A: The MAX9316EWP+ has been discontinued by the manufacturer. The MAX9315EUP+ represents the active equivalent in the product line and is the recommended choice for ongoing production and new designs.

Q: What packaging format does the MAX9315EUP+ use?

A: The MAX9315EUP+ is supplied in a 20-TSSOP (Thin Shrink Small Outline Package) format with a width of 0.173" (4.40mm), compared to the 20-SOIC format of the original part.
