MAX4608CSE Equivalent & Substitute Parts

Part Overview

The MAX4608CSE is a 2-circuit IC switch with SPST-NO (Single Pole Single Throw - Normally Open) configuration, manufactured by Analog Devices Inc./Maxim Integrated. This component features 2.5Ohm on-state resistance and operates across a wide supply voltage range of 4.5V to 36V (single supply) or ±4.5V to ±20V (dual supply). The device is housed in a 16-SOIC surface mount package.

The MAX4608CSE is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this interface component.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4608CSE is determined by strict equivalence across the following critical parameters:

Switch circuit configuration (SPST - NO)
Number of circuits (2)
Multiplexer/Demultiplexer circuit ratio (1:1)
On-state resistance maximum (2.5Ohm)
Channel-to-channel matching (50mOhm)
Supply voltage ranges (4.5V ~ 36V single; ±4.5V ~ 20V dual)
Switch timing specifications (110ns, 150ns)
Charge injection (45pC)
Channel capacitance values (64pF, 64pF)
Leakage current maximum (500pA)
Crosstalk performance (-66dB @ 1MHz)
Operating temperature range (0°C ~ 70°C)
Package type (16-SOIC)

The MAX4608CSE+ meets all these criteria and qualifies as a direct substitute.

Engineering Selection Recommendations

The MAX4608CSE+ is the direct substitute for the MAX4608CSE. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all functional parameters.

The primary distinction between these parts is product status and regulatory compliance. The MAX4608CSE is obsolete, while the MAX4608CSE+ maintains active product status. Additionally, the MAX4608CSE+ is ROHS3 compliant, whereas the original MAX4608CSE is RoHS non-compliant. Both parts carry REACH Unaffected status and EAR99 export classification.

For new designs and ongoing production support, the MAX4608CSE+ is the appropriate selection due to its active availability and enhanced regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the MAX4608CSE+ be used as a direct replacement for the MAX4608CSE?

A: Yes. The MAX4608CSE+ is electrically and mechanically identical to the MAX4608CSE across all specified parameters, including switch configuration, on-state resistance, supply voltage ranges, timing characteristics, and package type. Both parts are housed in 16-SOIC surface mount packages with identical pinout and functional behavior.

Q: What is the primary reason to transition from MAX4608CSE to MAX4608CSE+?

A: The MAX4608CSE is classified as obsolete, creating supply chain risk. The MAX4608CSE+ is an active product with ongoing manufacturer support and availability. Additionally, the MAX4608CSE+ is ROHS3 compliant, meeting current regulatory requirements, whereas the MAX4608CSE is RoHS non-compliant.

Q: Are there any differences in packaging between these parts?

A: Both parts use the same 16-SOIC (0.154", 3.90mm Width) surface mount package. The primary packaging difference is that the MAX4608CSE+ is supplied in Tube packaging, while the original MAX4608CSE packaging specification is not detailed. This does not affect electrical or mechanical compatibility.

Q: What electrical parameters must match for substitution eligibility?

A: Critical parameters include SPST-NO switch configuration, 2-circuit count, 1:1 multiplexer ratio, 2.5Ohm maximum on-state resistance, 50mOhm channel-to-channel matching, 4.5V to 36V single supply voltage range, ±4.5V to ±20V dual supply voltage range, 110ns/150ns switch timing, 45pC charge injection, 64pF channel capacitance, 500pA maximum leakage current, and -66dB crosstalk at 1MHz.

Q: Is the operating temperature range identical between both parts?

A: Yes. Both the MAX4608CSE and MAX4608CSE+ operate across the same temperature range of 0°C to 70°C (TA).
