Substitute Part Grouping Explanation

Substitution eligibility for the MAX339CSE is determined by strict equivalence across the following critical parameters:

Switch circuit topology: SP4T configuration with 2 independent circuits
Multiplexer function: 4:1 switching capability
On-state resistance: 400Ohm maximum
Channel matching: 4Ohm maximum ΔRon
Supply voltage ranges: 4.5V ~ 30V (single) and ±4.5V ~ 20V (dual)
Switching performance: 500ns maximum for both Ton and Toff
Electrical characteristics: Charge injection (1.5pC), leakage current (20pA max), crosstalk (-92dB @ 100kHz)
Package compatibility: 16-SOIC surface mount form factor
Temperature range: 0°C ~ 70°C operating specification

Only parts meeting all these parameters qualify as direct substitutes. The MAX339CSE+ maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Engineering Selection Recommendations

The MAX339CSE+ is the direct substitute for the MAX339CSE. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction lies in product lifecycle status and regulatory compliance:

The MAX339CSE is classified as obsolete, indicating discontinued manufacturing and limited availability. The MAX339CSE+ maintains active product status with ongoing manufacturing support and availability.

From a compliance perspective, the MAX339CSE+ is ROHS3 compliant, whereas the original MAX339CSE is RoHS non-compliant. For applications subject to RoHS regulations or requiring long-term supply chain stability, the MAX339CSE+ is the appropriate selection.

Both parts share identical electrical performance characteristics, package geometry, and thermal specifications, ensuring direct pin-for-pin and functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can MAX339CSE+ be used as a direct replacement for MAX339CSE in existing designs?

A: Yes. The MAX339CSE+ is electrically and mechanically identical to the MAX339CSE. All electrical parameters, switching characteristics, supply voltage ranges, and package dimensions are equivalent. No circuit modifications are required.

Q: What is the difference between MAX339CSE and MAX339CSE+?

A: The primary differences are product status and compliance certification. The MAX339CSE is obsolete with RoHS non-compliant status. The MAX339CSE+ is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 16-SOIC surface mount package with identical pinout and mechanical dimensions (0.154" width, 3.90mm). They are fully interchangeable at the PCB level.

Q: Why is the MAX339CSE classified as obsolete?

A: The MAX339CSE has been discontinued by the manufacturer. The MAX339CSE+ represents the current active product offering with the same functionality and specifications.

Q: What supply voltage configurations does this IC support?

A: The MAX339CSE and MAX339CSE+ support both single and dual supply configurations. Single supply operation ranges from 4.5V to 30V. Dual supply operation ranges from ±4.5V to ±20V.

Q: What is the on-state resistance specification?

A: The maximum on-state resistance is 400Ohm with channel-to-channel matching of 4Ohm maximum (ΔRon). This specification is identical for both the MAX339CSE and MAX339CSE+.

Q: What switching speed can be expected from this IC?

A: Both turn-on (Ton) and turn-off (Toff) times are specified at 500ns maximum, enabling switching applications up to approximately 1MHz.
