MAX368EPN Equivalent & Substitute Parts

Part Overview

The MAX368EPN is an 8:1 analog multiplexer/demultiplexer IC manufactured by Analog Devices Inc./Maxim Integrated. This single-circuit switch device features 1.8kOhm on-state resistance and operates across a dual supply voltage range of ±4.5V to ±18V. The component is housed in an 18-pin DIP package suitable for through-hole mounting applications. As an obsolete product, identifying functionally equivalent alternatives is necessary for system redesign, legacy equipment maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX368EPN is determined by strict equivalence across the following critical parameters:

• Multiplexer Configuration: 8:1 topology (mandatory match)
• Circuit Count: Single circuit (mandatory match)
• On-State Resistance: 1.8kOhm maximum (mandatory match)
• Channel Matching: 180Ohm ΔRon (mandatory match)
• Supply Voltage Range: ±4.5V ~ 18V dual supply (mandatory match)
• Switching Performance: 1.5µs Ton, 1µs Toff (mandatory match)
• Charge Injection: 55pC (mandatory match)
• Package: 18-DIP through-hole (mandatory match)
• Operating Temperature: -40°C ~ 85°C (mandatory match)

The MAX368EPN+ meets all electrical and mechanical parameters required for direct substitution. Differences in packaging format (tube vs. standard) and RoHS compliance status do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MAX368EPN+ provides direct functional equivalence to the MAX368EPN across all electrical and mechanical specifications. Both components are classified as obsolete products. The primary distinction between these parts is regulatory compliance: the MAX368EPN+ achieves ROHS3 compliance, while the original MAX368EPN does not. For new designs or systems requiring RoHS compliance, the MAX368EPN+ is the appropriate selection. For legacy system maintenance where original specifications must be preserved, either part satisfies the technical requirements. Both components maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can MAX368EPN+ replace MAX368EPN in existing designs? A: Yes. The MAX368EPN+ is electrically and mechanically identical to the MAX368EPN. All switching characteristics, supply voltage ranges, timing parameters, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between MAX368EPN and MAX368EPN+? A: The primary difference is packaging format and RoHS compliance status. The MAX368EPN+ is supplied in tube packaging and meets ROHS3 compliance requirements, while the MAX368EPN does not. Electrical performance and pin configuration are identical.

Q: Are both parts suitable for -40°C to 85°C operating environments? A: Yes. Both MAX368EPN and MAX368EPN+ are rated for -40°C to 85°C operating temperature range.

Q: Does the 18-DIP package remain the same for both parts? A: Yes. Both components use the same 18-DIP (0.300", 7.62mm) through-hole package. PCB layout and mounting procedures are identical.

Q: Which part should be selected for new production? A: The MAX368EPN+ is recommended for new production due to ROHS3 compliance alignment with current regulatory requirements. Both parts are obsolete, so availability should be verified with component suppliers.

Q: Are there any supply voltage compatibility concerns? A: No. Both parts operate identically across the ±4.5V to ±18V dual supply voltage range. No supply circuit modifications are required when substituting between these parts.
