MAX4522EEE Equivalent & Substitute Parts

Part Overview

The MAX4522EEE is a 4-circuit IC switch with SPST-NO (Single Pole Single Throw - Normally Open) configuration manufactured by Analog Devices Inc./Maxim Integrated. This interface component operates across single supply voltages of 2V to 12V or dual supply voltages of ±2V to 6V, making it suitable for signal routing and switching applications in analog systems.

The MAX4522EEE is classified as obsolete, which necessitates identification of equivalent substitute parts for new designs and ongoing production requirements. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity and supply chain reliability.

Engineering Selection Recommendations

The MAX4522EEE+ is the direct substitute for the obsolete MAX4522EEE. Both parts maintain identical electrical performance and mechanical compatibility, with all switching characteristics, supply voltage ranges, and package specifications matching exactly.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX4522EEE is obsolete and no longer in active production, while the MAX4522EEE+ maintains active product status with ROHS3 compliance certification. For new designs and ongoing production, the MAX4522EEE+ is the appropriate selection to ensure supply chain continuity and regulatory alignment.

Both parts are RoHS-affected components with REACH unaffected status and EAR99 export classification. The packaging difference (tube for MAX4522EEE+ versus unspecified for MAX4522EEE) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the MAX4522EEE and MAX4522EEE+ electrically identical?

A: Yes. Both parts share identical electrical specifications including on-state resistance of 100Ω, switching times of 80ns/30ns, supply voltage ranges of 2V ~ 12V (single) or ±2V ~ 6V (dual), and all signal integrity parameters.

Q: Can I use MAX4522EEE+ as a direct replacement for MAX4522EEE in existing designs?

A: Yes. The MAX4522EEE+ is a direct substitute with identical package, pinout, and electrical performance. No circuit modifications are required.

Q: What is the difference between these parts?

A: The MAX4522EEE is obsolete, while the MAX4522EEE+ is active. The MAX4522EEE+ also carries ROHS3 compliance certification, whereas the MAX4522EEE is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any supply voltage or temperature range differences?

A: No. Both parts operate across identical supply voltage ranges (2V ~ 12V single or ±2V ~ 6V dual) and temperature ranges (-40°C to 85°C).

Q: Does the packaging format affect compatibility?

A: No. Both parts use the 16-SSOP surface mount package with 0.154" width (3.90mm). The packaging format difference (tube for MAX4522EEE+) relates only to shipment and handling, not electrical or mechanical compatibility.

Q: What is the on-state resistance specification?

A: The maximum on-state resistance is 100Ω with channel-to-channel matching of 1Ω, ensuring consistent performance across all four circuits.
