MAX336EUI+ Equivalent & Substitute Parts

Part Overview

The MAX336EUI+ is a 16:1 analog multiplexer/demultiplexer integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This single-circuit switch device operates across a wide supply voltage range and is designed for signal routing applications requiring low on-state resistance and minimal crosstalk. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative sourcing options when the primary part becomes unavailable or when design specifications require functional equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX336EUI+ must satisfy the following critical parameters to ensure functional equivalence:

• Multiplexer/Demultiplexer configuration of 16:1
• Single circuit topology
• On-state resistance maximum of 400Ohm
• Channel-to-channel matching (ΔRon) of 5Ohm or better
• Supply voltage compatibility: Single supply 4.5V ~ 30V or dual supply ±4.5V ~ 20V
• Switch timing specifications: Ton and Toff maximum of 500ns
• Charge injection of 4.6pC or lower
• Channel capacitance specifications: CS(off) 2pF, CD(off) 20pF
• Leakage current (IS(off)) maximum of 20pA
• Crosstalk performance of -86dB @ 100kHz or better
• Operating temperature range: -40°C ~ 85°C
• 28-TSSOP surface mount package
• ROHS3 compliance and MSL 1 rating

Parts meeting all these parameters are considered direct functional equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The MAX336EUI+ is an active production part with full ROHS3 compliance and MSL 1 rating, indicating mature manufacturing status and environmental regulatory compliance. When selecting substitute parts, prioritize components with identical active production status and matching compliance certifications. The ROHS3 compliance and unlimited moisture sensitivity rating ensure compatibility with modern manufacturing processes and long-term storage requirements. Parts meeting all specified electrical and mechanical parameters are suitable for direct substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX336EUI+? A: A valid substitute must match all critical parameters: 16:1 multiplexer configuration, 400Ohm maximum on-state resistance, 5Ohm channel matching, compatible supply voltage ranges, 500ns switch timing, 4.6pC charge injection, specified channel capacitance, 20pA maximum leakage, -86dB crosstalk performance, -40°C to 85°C operating temperature, 28-TSSOP package, and ROHS3 compliance.

Q: Can the MAX336EUI+ be replaced with a different package type? A: No. The 28-TSSOP surface mount package is a critical specification. Package changes require PCB redesign and are not considered direct substitution.

Q: Are there any supply voltage restrictions when substituting? A: Substitute parts must support the same supply voltage ranges: single supply 4.5V ~ 30V or dual supply ±4.5V ~ 20V. Your circuit design determines which supply configuration applies.

Q: What is the significance of the 5Ohm channel-to-channel matching specification? A: Channel-to-channel matching (ΔRon) ensures consistent on-state resistance across all 16 channels. The 5Ohm specification is critical for applications requiring uniform signal attenuation across multiplexed channels.

Q: Does the crosstalk specification affect substitution decisions? A: Yes. The -86dB @ 100kHz crosstalk specification is a key performance parameter. Substitute parts must meet or exceed this specification to prevent signal interference between channels.

Q: Is the MSL 1 rating important for component selection? A: Yes. MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling, simplifying supply chain management.
