MAX4518CEE Equivalent & Substitute Parts

Part Overview

The MAX4518CEE is a single-circuit SP4T (Single Pole, 4-Throw) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This interface component operates as a 4:1 multiplexer/demultiplexer with 100Ohm on-state resistance and is packaged in a 16-QSOP surface mount configuration. The MAX4518CEE is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution of the MAX4518CEE is determined by strict equivalence across the following critical parameters:

Switch circuit topology: SP4T configuration
Multiplexer function: 4:1 circuit
Single circuit count
On-state resistance: 100Ohm maximum
Channel-to-channel matching: 4Ohm maximum
Supply voltage ranges: 2V ~ 15V (single) and ±2.7V ~ 8V (dual)
Switching performance: 150ns maximum for both Ton and Toff
Electrical characteristics: Charge injection, channel capacitance, leakage current, and crosstalk specifications
Physical form factor: 16-QSOP surface mount package
Moisture sensitivity: MSL 1

The MAX4518CEE+ meets all these criteria and is therefore a direct functional equivalent.

Engineering Selection Recommendations

The MAX4518CEE+ is the direct substitute for the MAX4518CEE. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance:

The MAX4518CEE is obsolete and no longer in active production
The MAX4518CEE+ is active and currently manufactured
The MAX4518CEE+ achieves ROHS3 compliance, whereas the original MAX4518CEE is RoHS non-compliant

For new designs and production applications requiring this SP4T 4:1 multiplexer switch, the MAX4518CEE+ is the appropriate selection. Both parts maintain identical performance characteristics, package form factor, and electrical specifications, ensuring direct compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can MAX4518CEE+ be used as a direct replacement for MAX4518CEE in existing designs?

A: Yes. The MAX4518CEE+ is electrically and mechanically identical to the MAX4518CEE. All electrical parameters, switching characteristics, supply voltage ranges, and package dimensions are equivalent. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between MAX4518CEE and MAX4518CEE+?

A: The primary differences are product status and regulatory compliance. The MAX4518CEE is obsolete, while the MAX4518CEE+ is an active product. The MAX4518CEE+ meets ROHS3 compliance standards, whereas the MAX4518CEE is RoHS non-compliant. All electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 16-QSOP surface mount package with identical dimensions (16-SSOP, 0.154", 3.90mm Width). The MAX4518CEE+ is supplied in Tube packaging, while the original MAX4518CEE packaging is not specified. This does not affect electrical performance or PCB assembly compatibility.

Q: What supply voltage configurations does this switch support?

A: The MAX4518CEE and MAX4518CEE+ support both single and dual supply configurations. Single supply operation ranges from 2V to 15V (V+). Dual supply operation ranges from ±2.7V to ±8V (V±).

Q: What is the on-state resistance specification?

A: The on-state resistance is 100Ohm maximum with channel-to-channel matching of 4Ohm maximum (ΔRon). This specification is identical across both the MAX4518CEE and MAX4518CEE+.

Q: What switching speed does this IC provide?

A: Both Ton and Toff switching times are 150ns maximum. This specification applies to both the MAX4518CEE and MAX4518CEE+.
