MAX4558CEE Equivalent & Substitute Parts

Part Overview

The MAX4558CEE is an 8:1 analog multiplexer/demultiplexer IC manufactured by Analog Devices Inc./Maxim Integrated. This single-circuit switch device features 160Ω on-state resistance and operates across single supply (2V to 12V) or dual supply (±2V to ±6V) configurations. The component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The MAX4558CEE+ provides direct functional equivalence with current product status and improved compliance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4558CEE is determined by strict equivalence across the following electrical and mechanical parameters:

Multiplexer configuration: 8:1 topology with single circuit
On-state resistance: 160Ω maximum
Channel-to-channel matching: 2Ω maximum
Supply voltage ranges: Single supply 2V–12V and dual supply ±2V–±6V
Switching performance: Ton/Toff specifications of 150ns/120ns
Signal integrity metrics: Charge injection, channel capacitance, leakage current, and crosstalk
Operating temperature range: 0°C to 70°C
Package specification: 16-SSOP surface mount

The MAX4558CEE+ meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in new designs and production applications.

Engineering Selection Recommendations

The MAX4558CEE+ is the direct equivalent for MAX4558CEE applications. Selection rationale is based on the following factors:

Product Status: The MAX4558CEE is obsolete, while MAX4558CEE+ maintains active product status with ongoing manufacturer support and availability.

Compliance: MAX4558CEE+ achieves ROHS3 compliance, whereas the original MAX4558CEE is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations and procurement standards requiring compliant components.

Electrical and Mechanical Equivalence: All functional parameters—multiplexer topology, on-state resistance, supply voltage ranges, switching characteristics, signal integrity metrics, operating temperature, and package specifications—are identical between the two parts.

Availability: MAX4558CEE+ inventory (747 pcs) supports production requirements, whereas MAX4558CEE stock (2200 pcs) represents obsolete inventory with limited future availability.

For new designs, production transitions, and component replenishment, MAX4558CEE+ is the appropriate selection. Existing designs using MAX4558CEE may continue operation without modification, as the substitute maintains full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX4558CEE+ directly replace MAX4558CEE in existing circuits?

A: Yes. The MAX4558CEE+ is electrically and mechanically identical to MAX4558CEE across all specified parameters. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference?

A: MAX4558CEE is classified as obsolete, indicating discontinued manufacturing and limited future availability. MAX4558CEE+ is active, ensuring ongoing supply, technical support, and compliance with current standards.

Q: Does the RoHS3 compliance of MAX4558CEE+ affect circuit performance?

A: No. RoHS3 compliance reflects manufacturing process improvements and environmental standards adherence. Electrical performance and functional characteristics remain unchanged.

Q: Are the package dimensions identical?

A: Yes. Both parts use 16-SSOP surface mount packaging with 0.154" (3.90mm) width. PCB footprints and assembly processes are identical.

Q: What supply voltage configurations are supported?

A: Both parts support single supply operation (2V to 12V) and dual supply operation (±2V to ±6V). Circuit design flexibility is maintained across both configurations.

Q: Is the switching speed identical between the two parts?

A: Yes. Both parts specify identical switch times: Ton maximum 150ns and Toff maximum 120ns. Signal timing and multiplexer response characteristics are equivalent.
