MAX350EAP Equivalent & Substitute Parts

Part Overview

The MAX350EAP is a dual-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 housed in a 20-SSOP surface mount package. The MAX350EAP is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support, design updates, and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX350EAP is determined by strict equivalence across the following critical parameters:

• Switch Circuit Configuration: Must be SP4T
• Multiplexer/Demultiplexer Circuit: Must be 4:1
• Number of Circuits: Must be 2
• On-State Resistance (Max): Must be 100Ohm
• Channel-to-Channel Matching (ΔRon): Must be 16Ohm (Max)
• Voltage - Supply, Single (V+): Must be 2.7V ~ 16V
• Voltage - Supply, Dual (V±): Must be ±2.7V ~ 8V
• Switch Time (Ton, Toff) (Max): Must be 275ns, 150ns
• Charge Injection: Must be 1pC
• Channel Capacitance (CS(off), CD(off)): Must be 2pF, 2pF
• Current - Leakage (IS(off)) (Max): Must be 100pA
• Crosstalk: Must be -90dB @ 100kHz
• Operating Temperature: Must be -40°C ~ 85°C (TA)
• Package / Case: Must be 20-SSOP (0.209", 5.30mm Width)
• Moisture Sensitivity Level (MSL): Must be 1 (Unlimited)

The MAX350EAP+ meets all substitution criteria and is identified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The MAX350EAP+ is the direct substitute for the obsolete MAX350EAP. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance:

• MAX350EAP: Obsolete product status with RoHS non-compliant classification
• MAX350EAP+: Active product status with ROHS3 compliance

For new designs, system updates, or ongoing procurement, the MAX350EAP+ is the appropriate selection. The active product status ensures continued availability and manufacturer support. ROHS3 compliance aligns with current environmental and regulatory requirements for electronic components in most markets.

Frequently Asked Questions (FAQ)

Q: Can MAX350EAP+ be used as a direct replacement for MAX350EAP in existing designs?

A: Yes. The MAX350EAP+ is electrically and mechanically equivalent to the MAX350EAP across all specified parameters, including switch circuit configuration, on-state resistance, voltage ratings, switching characteristics, and package dimensions. No circuit modifications are required.

Q: What is the difference between MAX350EAP and MAX350EAP+?

A: The parts are functionally identical. The primary differences are product status (MAX350EAP is obsolete; MAX350EAP+ is active) and regulatory compliance (MAX350EAP is RoHS non-compliant; MAX350EAP+ is ROHS3 compliant).

Q: Are there packaging differences between MAX350EAP and MAX350EAP+?

A: Both parts use the 20-SSOP package with identical dimensions (0.209", 5.30mm Width). The MAX350EAP+ is supplied in Tube packaging, while the MAX350EAP packaging specification was not provided.

Q: Is the MAX350EAP+ suitable for applications requiring RoHS compliance?

A: Yes. The MAX350EAP+ carries ROHS3 compliance certification, making it suitable for applications and markets with RoHS requirements.

Q: What is the operating temperature range for both parts?

A: Both the MAX350EAP and MAX350EAP+ operate across -40°C to 85°C (TA).
