MAX4556ESE Equivalent & Substitute Parts

Part Overview

The MAX4556ESE is a triple SPDT (Single Pole Double Throw) switch IC manufactured by Analog Devices Inc./Maxim Integrated, designed for force sense applications requiring multiplexer/demultiplexer functionality. This component operates across a wide supply voltage range (9V to 40V single supply, or ±4.5V to ±20V dual supply) and features break-before-make switching with low on-state resistance of 6Ω maximum.

The MAX4556ESE is classified as obsolete. Locating direct equivalents or suitable substitutes is necessary for ongoing production, maintenance, and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4556ESE is determined by strict equivalence across the following critical parameters:

• Switch circuit configuration: SPDT topology with 3 channels
• On-state resistance: 6Ω maximum
• Supply voltage ranges: 9V–40V (single) and ±4.5V–±20V (dual)
• Break-before-make switching behavior
• Operating temperature range: -40°C to 85°C
• Package format: 16-SOIC surface mount
• Multiplexer/demultiplexer circuit: 2:1 configuration

Only components matching all these parameters across electrical and mechanical specifications qualify as direct substitutes. The MAX4556ESE+ meets these criteria and is listed as a direct manufacturer equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX4556ESE+ is the direct functional and electrical equivalent of the MAX4556ESE. Both components share identical electrical specifications, pin configurations, and package geometry, ensuring drop-in compatibility at the circuit level.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX4556ESE is obsolete, while the MAX4556ESE+ maintains active production status. Additionally, the MAX4556ESE+ achieves ROHS3 compliance, whereas the original MAX4556ESE is RoHS non-compliant. For new designs or production requiring regulatory compliance with current environmental standards, the MAX4556ESE+ is the appropriate selection.

Both components maintain identical moisture sensitivity levels (MSL 1, Unlimited) and REACH status, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAX4556ESE+ be used as a direct replacement for the MAX4556ESE in existing designs?

A: Yes. The MAX4556ESE+ is electrically and mechanically identical to the MAX4556ESE. All electrical parameters, pin assignments, and package dimensions are equivalent, enabling direct substitution without circuit modifications.

Q: What is the primary reason to transition from MAX4556ESE to MAX4556ESE+?

A: The MAX4556ESE is obsolete and no longer in production. The MAX4556ESE+ is the active equivalent from the same manufacturer, ensuring continued component availability. Additionally, the MAX4556ESE+ meets ROHS3 compliance requirements, whereas the original part does not.

Q: Are there any differences in handling or storage between these two parts?

A: No. Both components share identical moisture sensitivity levels (MSL 1, Unlimited), requiring the same handling, storage, and packaging protocols.

Q: Does the package format remain the same between the two parts?

A: Yes. Both the MAX4556ESE and MAX4556ESE+ use the 16-SOIC surface mount package with identical dimensions (0.154" width, 3.90mm).

Q: Are supply voltage specifications identical between these parts?

A: Yes. Both components support single supply operation from 9V to 40V and dual supply operation from ±4.5V to ±20V, with identical on-state resistance of 6Ω maximum.
