MAX4664EPE Equivalent & Substitute Parts

Part Overview

The MAX4664EPE is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 4Ohm on-state resistance and is housed in a 16-DIP through-hole package. The MAX4664EPE is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4664EPE is determined by the following critical parameters:

Switch circuit configuration (SPST - NC)
Number of circuits (4)
On-state resistance (4Ohm maximum)
Channel-to-channel matching (200mOhm)
Supply voltage ranges (single and dual)
Package type (16-DIP through-hole)
Mounting compatibility (through-hole)

The MAX4604CPE+ and MAX4601EPE+ meet these core electrical and mechanical requirements, establishing them as valid substitutes. Both parts maintain identical switch topology, circuit count, resistance specifications, and package form factor.

Engineering Selection Recommendations

The MAX4604CPE+ is the primary substitute for the MAX4664EPE. This part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring long-term availability and technical support. The MAX4604CPE+ achieves ROHS3 compliance, addressing environmental and regulatory requirements that the obsolete MAX4664EPE does not meet. Electrical parameters remain equivalent across core specifications: 4Ohm on-state resistance, 200mOhm channel matching, and identical supply voltage ranges.

The MAX4604CPE+ demonstrates improved performance characteristics in switch timing (120ns/130ns versus 275ns/175ns) and reduced charge injection (225pC versus 300pC), providing enhanced signal integrity in switching applications. Operating temperature range narrows to 0°C ~ 70°C, which is suitable for standard industrial and commercial environments.

The MAX4601EPE+ is listed as an alternative substitute but carries obsolete product status. Limited technical parameter data is provided for this part, restricting its suitability for new designs. This part is appropriate only for legacy system maintenance where MAX4664EPE inventory is depleted.

Frequently Asked Questions (FAQ)

Q: Can MAX4604CPE+ directly replace MAX4664EPE in existing designs?

A: The MAX4604CPE+ is electrically and mechanically compatible with the MAX4664EPE. Both parts feature identical switch topology (SPST-NC), circuit count (4), on-state resistance (4Ohm), channel matching (200mOhm), and package form factor (16-DIP through-hole). The narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C) must be verified against application requirements.

Q: What is the primary advantage of MAX4604CPE+ over MAX4664EPE?

A: The MAX4604CPE+ is an active product with ROHS3 compliance, ensuring regulatory alignment and long-term supply chain stability. Performance improvements include faster switch times and lower charge injection, benefiting high-frequency switching applications.

Q: Are there packaging differences between these parts?

A: All three parts use identical 16-DIP (0.300", 7.62mm) through-hole packages. Packaging format differs only in supplier delivery method: MAX4664EPE (standard), MAX4604CPE+ (tube), and MAX4601EPE+ (bulk). PCB footprint and mounting procedures remain unchanged.

Q: Is MAX4601EPE+ suitable for new designs?

A: MAX4601EPE+ carries obsolete product status. Use this part only for legacy system maintenance. For new designs, MAX4604CPE+ is the recommended substitute.

Q: What compliance certifications apply to these parts?

A: MAX4664EPE is RoHS non-compliant. MAX4604CPE+ and MAX4601EPE+ both achieve ROHS3 compliance. All three parts are REACH Unaffected and classified under ECCN EAR99.
