MAX4066EPD+ Equivalent & Substitute Parts

Part Overview

The MAX4066EPD+ is a 4-circuit IC switch manufactured by Analog Devices Inc./Maxim Integrated, classified as an Interface component in the SPST-NO (Single Pole Single Throw - Normally Open) switch category. This part is designated as Obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

The MAX4066EPD+ serves as a general-purpose analog switch suitable for signal routing and multiplexing applications. Due to its obsolete status, equivalent parts from active manufacturers must be evaluated to maintain design continuity and ensure component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4066EPD+ is determined by the following critical parameters:

• Circuit Configuration: 4-circuit SPST-NO switch topology
• Multiplexer Ratio: 1:1 channel configuration
• Compliance Standards: ROHS3 compliance and REACH unaffected status
• Environmental Classification: MSL rating compatibility
• Functional Equivalence: Identical switch circuit architecture and pin count

The CD74HC4066E from Texas Instruments meets all substitution criteria as an active, Last Time Buy component with identical circuit topology, configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4066E is the primary equivalent substitute for the MAX4066EPD+. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The CD74HC4066E carries Last Time Buy status from Texas Instruments, indicating continued but limited availability.

For applications requiring the MAX4066EPD+, the CD74HC4066E provides functional equivalence with documented electrical performance specifications. The through-hole 14-DIP package format ensures mechanical compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Why is the MAX4066EPD+ obsolete? A: The MAX4066EPD+ has reached end-of-life status from Analog Devices Inc./Maxim Integrated. The CD74HC4066E from Texas Instruments provides equivalent functionality for new designs and ongoing support.

Q: Are the MAX4066EPD+ and CD74HC4066E pin-compatible? A: Both components feature 4-circuit SPST-NO switch topology with identical circuit configuration. Pin compatibility must be verified against specific PCB layout and schematic requirements.

Q: What is the difference between Last Time Buy and Obsolete status? A: Obsolete status indicates the part is no longer manufactured or supported. Last Time Buy status indicates limited remaining inventory availability before discontinuation. The CD74HC4066E is in Last Time Buy phase, requiring timely procurement decisions.

Q: Are both parts RoHS compliant? A: Yes. Both the MAX4066EPD+ and CD74HC4066E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging format is used for the CD74HC4066E? A: The CD74HC4066E is supplied in 14-DIP (0.300", 7.62mm) through-hole package format, compatible with standard PCB assembly processes.
