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 of 1.5 GHz, supporting differential HSTL, LVECL, and LVPECL input/output standards. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. Substitute parts must maintain functional compatibility across clock distribution, frequency range, and signal integrity requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX9316EWP is determined by the following critical parameters:

• Functional Type: Fanout Buffer (Distribution) Multiplexer with 2:5 input-to-output ratio
• Frequency Capability: Maximum 1.5 GHz operation
• Differential Signal Support: Differential input and output capability
• Signal Standards: Support for HSTL, LVECL, and LVPECL standards
• Supply Voltage Range: Compatibility within or overlapping the 3V to 3.8V range
• Operating Temperature: -40°C to 85°C range
• Package Compatibility: Surface mount configuration

The MAX9315EUP+ qualifies as a direct substitute based on matching all critical functional parameters: identical 2:5 ratio, 1.5 GHz maximum frequency, differential input/output support, and compatible signal standards. The substitute maintains the same operating temperature range and surface mount technology. The primary difference is packaging format (20-TSSOP versus 20-SOIC) and expanded supply voltage range (2.25V ~ 3.8V versus 3V ~ 3.8V), with the substitute offering broader voltage compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX9315EUP+ is the qualified substitute for the obsolete MAX9316EWP. Selection of the MAX9315EUP+ provides the following advantages:

• Product Status: Active production status ensures long-term availability and supply chain continuity, eliminating obsolescence risk associated with the MAX9316EWP.
• Regulatory Compliance: ROHS3 compliance of the MAX9315EUP+ meets current environmental and regulatory requirements, whereas the MAX9316EWP is non-compliant.
• Functional Equivalence: Identical clock distribution performance, frequency capability, and signal standard support ensure direct functional replacement in existing circuit designs.
• Voltage Flexibility: The expanded supply voltage range (2.25V ~ 3.8V) of the MAX9315EUP+ provides additional design flexibility compared to the MAX9316EWP (3V ~ 3.8V).
• Package Consideration: The 20-TSSOP package of the MAX9315EUP+ is smaller than the 20-SOIC package of the MAX9316EWP, requiring PCB layout modification but offering space efficiency benefits.

Frequently Asked Questions (FAQ)

Q: Can the MAX9315EUP+ directly replace the MAX9316EWP without circuit modification?

A: Functional replacement is direct due to identical input/output ratios, frequency specifications, and signal standards. However, package geometry differs (20-TSSOP versus 20-SOIC), requiring PCB footprint redesign and layout adjustment. Electrical performance and pinout compatibility are maintained.

Q: What is the impact of the different package types?

A: The MAX9315EUP+ uses a 20-TSSOP package (0.173" width) compared to the MAX9316EWP's 20-SOIC package (0.295" width). The TSSOP package is narrower and more compact. PCB layout and footprint must be updated accordingly, but electrical functionality remains identical.

Q: Does the expanded supply voltage range of the MAX9315EUP+ affect compatibility?

A: The MAX9315EUP+ operates across 2.25V ~ 3.8V, while the MAX9316EWP operates across 3V ~ 3.8V. The substitute's broader range is fully compatible with designs operating within the original 3V ~ 3.8V specification. No circuit modification is required for voltage compatibility.

Q: Why is RoHS compliance important for this substitution?

A: The MAX9315EUP+ is ROHS3 compliant, meeting current environmental regulations and manufacturing standards. The obsolete MAX9316EWP is non-compliant. For new production and designs subject to regulatory requirements, the compliant substitute is necessary.

Q: Are there any signal integrity differences between these parts?

A: Both parts support identical differential input/output standards (HSTL, LVECL, LVPECL) and operate at the same maximum frequency (1.5 GHz). Signal integrity performance is equivalent across the specified operating range.
