MAX4518EEE Equivalent & Substitute Parts

Part Overview

The MAX4518EEE is a single-circuit SP4T (Single Pole, 4-Throw) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component functions as a 4:1 multiplexer/demultiplexer with 100Ohm on-state resistance, designed for signal routing applications in analog and mixed-signal systems. The MAX4518EEE is classified as obsolete, making identification of compatible substitute parts essential for ongoing production support and design continuity.

Substitute Part Grouping Explanation

Substitution of the MAX4518EEE is determined by strict equivalence across the following critical parameters:

Switch circuit topology: SP4T configuration with 4:1 multiplexing capability
On-state resistance: 100Ohm maximum
Channel-to-channel matching: 4Ohm maximum variation
Supply voltage ranges: Single supply 2V ~ 15V and dual supply ±2.7V ~ 8V
Switching performance: 150ns maximum for both Ton and Toff
Electrical characteristics: Charge injection, channel capacitance, leakage current, and crosstalk specifications
Package compatibility: 16-SSOP surface mount package with 16-QSOP supplier designation
Operating temperature range: -40°C ~ 85°C

The MAX4518EEE+ meets all these criteria and is therefore a direct functional equivalent.

Engineering Selection Recommendations

The MAX4518EEE+ is the direct substitute for the obsolete MAX4518EEE. 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 lifecycle status and regulatory compliance. The MAX4518EEE is classified as obsolete, while the MAX4518EEE+ maintains active product status. Additionally, the MAX4518EEE+ achieves ROHS3 compliance, whereas the original MAX4518EEE is RoHS non-compliant. Both parts maintain identical moisture sensitivity levels and REACH status.

For new designs and ongoing production requiring SP4T analog switch functionality with 100Ohm on-state resistance in a 16-QSOP package, the MAX4518EEE+ is the appropriate selection. For legacy systems currently using the MAX4518EEE, direct substitution with the MAX4518EEE+ is electrically and mechanically compatible without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the MAX4518EEE+ directly replace the MAX4518EEE in existing designs?

A: Yes. The MAX4518EEE+ is electrically and mechanically equivalent to the MAX4518EEE.
