MAX365ESE IC Switch SPST-NO 4 Circuit 85Ohm 16-SOIC Equivalent & Substitute Parts

Part Overview

The MAX365ESE is a 4-circuit SPST-NO (Single Pole Single Throw - Normally Open) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 85Ohm on-state resistance and is housed in a 16-SOIC surface mount package. The MAX365ESE is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Active alternatives with identical or superior electrical characteristics are available from both Analog Devices and Vishay Siliconix.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX365ESE is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Switch circuit type: SPST - NO
• Number of circuits: 4
• Multiplexer/Demultiplexer configuration: 1:1
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 85°C (TA)

Electrical Performance Parameters:

• On-state resistance (Max): 85Ohm or lower
• Channel-to-channel matching (ΔRon): 2Ohm (Max) or better
• Voltage supply ranges: Single supply 10V ~ 30V or dual supply ±4.5V ~ 20V (or broader ranges)
• Switch time specifications: Ton and Toff within acceptable limits
• Charge injection: 5pC or lower
• Channel capacitance: 4pF or lower
• Leakage current: 500pA or lower
• Crosstalk: -100dB @ 1MHz or better

Substitute Parts Identified:

1. Direct Manufacturer Equivalent (Analog Devices): MAX365ESE+ - Identical electrical specifications with active product status and RoHS3 compliance
2. Parametric Equivalent (Analog Devices): MAX362ESE+ - Identical electrical specifications with active product status and RoHS3 compliance
3. MFR Recommended Alternative (Vishay Siliconix): DG412DY-E3 and DG412DY-T1-E3 - Superior on-state resistance (35Ohm vs 85Ohm), faster switching times, broader supply voltage range, and RoHS3 compliance

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

The MAX365ESE+ and MAX362ESE+ are direct substitutes for the obsolete MAX365ESE. Both parts maintain identical electrical specifications and operating parameters. The MAX365ESE+ is the primary recommendation due to its matching base product number. Both alternatives carry active product status and ROHS3 compliance, addressing regulatory requirements that the original MAX365ESE does not meet. Inventory availability is adequate for both parts (3100 and 3200 units respectively).

For Enhanced Performance Alternative:

The DG412DY-E3 and DG412DY-T1-E3 (Vishay Siliconix) offer superior electrical characteristics including 35Ohm on-state resistance (58% lower than MAX365ESE), faster switching times (Ton reduced from 250ns to 175ns), lower leakage current (250pA vs 500pA), and broader single-supply voltage range (5V ~ 44V vs 10V ~ 30V). These parts are suitable for applications where lower on-state resistance and faster switching are beneficial. Both variants are ROHS3 compliant and carry active product status. The DG412DY-T1-E3 offers superior inventory availability (20450 units) in Cut Tape and Digi-Reel packaging.

Compliance Considerations:

All substitute parts are ROHS3 compliant, whereas the original MAX365ESE is RoHS non-compliant. This compliance upgrade is significant for new designs and production environments subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can MAX365ESE+ be used as a direct drop-in replacement for MAX365ESE?

A: Yes. The MAX365ESE+ maintains identical electrical specifications, package configuration (16-SOIC), and pin compatibility. The primary difference is product status (active vs obsolete) and RoHS3 compliance. No circuit modifications are required.

Q: What is the difference between MAX365ESE+ and MAX362ESE+?

A: Both parts are parametrically equivalent with identical electrical specifications and operating ranges. The base product numbers differ (MAX365 vs MAX362), but all critical parameters including on-state resistance, switching times, supply voltages, and operating temperature are identical. Selection between these parts may be based on availability or supplier preference.

Q: Are the Vishay DG412DY variants compatible with MAX365ESE designs?

A: The DG412DY-E3 and DG412DY-T1-E3 are functionally compatible as 4-circuit SPST-NO switches in 16-SOIC packages. However, they offer different electrical characteristics. The 35Ohm on-state resistance (vs 85Ohm) and faster switching times represent performance improvements suitable for many applications. The broader supply voltage range (5V ~ 44V single supply) provides additional design flexibility. Applications sensitive to on-state resistance or crosstalk performance should evaluate these differences against circuit requirements.

Q: What is the difference between DG412DY-E3 and DG412DY-T1-E3?

A: Both parts are electrically identical. The primary difference is packaging format: DG412DY-E3 is supplied in Tube packaging, while DG412DY-T1-E3 is supplied in Cut Tape (CT) and Digi-Reel format. The DG412DY-T1-E3 offers significantly higher inventory availability (20450 units vs 2288 units). Selection depends on production volume requirements and handling preferences.

Q: Why does the MAX365ESE have higher on-state resistance than the DG412DY variants?

A: On-state resistance is a fundamental characteristic of the semiconductor design and manufacturing process. The MAX365ESE is specified at 85Ohm maximum, while the DG412DY series is specified at 35Ohm maximum. This difference reflects different design priorities and process technologies between Analog Devices and Vishay Siliconix. Applications requiring lower resistance should specify the DG412DY variants.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts (MAX365ESE+, MAX362ESE+, DG412DY-E3, and DG412DY-T1-E3) are housed in 16-SOIC packages with identical physical dimensions (0.154" width, 3.90mm). PCB footprints and assembly processes remain unchanged.

Q: What is the impact of the higher channel capacitance in DG412DY parts?

A: The DG412DY variants specify 9pF channel capacitance (CS(off), CD(off)) compared to 4pF for MAX365ESE. This higher capacitance may affect high-frequency performance in sensitive analog signal routing applications. Applications operating at frequencies where this capacitance becomes significant should evaluate circuit performance with the DG412DY specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. MAX365ESE+, MAX362ESE+, DG412DY-E3, and DG412DY-T1-E3 are all ROHS3 compliant. The original MAX365ESE is RoHS non-compliant. This compliance upgrade is mandatory for new designs and production environments subject to RoHS regulations.
