Substitute Part Grouping Explanation

Substitution eligibility for the MAX338CSE is determined by strict equivalence across the following critical parameters:

• Multiplexer configuration: 8:1
• Number of circuits: 1
• On-state resistance: 400Ohm maximum
• Channel-to-channel matching: 4Ohm
• Supply voltage ranges: Single 4.5V ~ 30V and dual ±4.5V ~ 20V
• Switch timing: 500ns maximum for both Ton and Toff
• Charge injection: 1.5pC
• Channel capacitance: 3pF (CS(off)) and 11pF (CD(off))
• Leakage current: 20pA maximum
• Crosstalk performance: -92dB @ 100kHz
• Operating temperature range: 0°C ~ 70°C
• Package type: 16-SOIC surface mount

The MAX338CSE+ meets all electrical and mechanical specifications required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MAX338CSE+ is the direct functional equivalent of the MAX338CSE, with identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: the MAX338CSE is obsolete while the MAX338CSE+ maintains active production status.

For new designs and ongoing system support, the MAX338CSE+ is the appropriate selection. This part offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant status of the original MAX338CSE. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

The identical 16-SOIC package footprint, electrical performance, and operating characteristics ensure direct pin-for-pin compatibility without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can MAX338CSE+ be used as a direct replacement for MAX338CSE in existing designs?

A: Yes. The MAX338CSE+ provides identical electrical performance and mechanical compatibility. Both parts feature the same 8:1 multiplexer configuration, 400Ohm on-state resistance, switching characteristics, and 16-SOIC package dimensions. No circuit redesign is required.

Q: What is the primary difference between MAX338CSE and MAX338CSE+?

A: The MAX338CSE+ is the active production variant with ROHS3 compliance, while the MAX338CSE is obsolete and RoHS non-compliant. All functional specifications remain identical.

Q: Are there packaging differences between these parts?

A: Both parts use 16-SOIC surface mount packaging with identical 0.154" (3.90mm) width. The MAX338CSE+ is supplied in Tube packaging, while the original MAX338CSE packaging specification was not provided.

Q: What supply voltage configurations are supported?

A: Both parts support single supply operation from 4.5V to 30V (V+) and dual supply operation from ±4.5V to ±20V (V±).

Q: Are these parts suitable for high-frequency applications?

A: Both parts provide -92dB crosstalk performance at 100kHz with 500ns maximum switching time and 1.5pC charge injection, supporting signal routing in audio, instrumentation, and data acquisition applications within the specified operating temperature range of 0°C to 70°C.
