MAX3384ECAP Equivalent & Substitute Parts

Part Overview

The MAX3384ECAP is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-SSOP surface mount package. This interface IC operates across a 3V to 5.5V supply range with a 250kbps data rate and 500mV receiver hysteresis. The part is currently obsolete, making equivalent substitutes necessary for new designs or component replenishment in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX3384ECAP is determined by strict equivalence across the following electrical and mechanical parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2
• Duplex: Full
• Data Rate: 250kbps
• Voltage - Supply: 3V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C
• Receiver Hysteresis: 500 mV
• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

All substitute parts listed below meet these core electrical and mechanical specifications. Differences in product status, RoHS compliance, and MSL rating are noted for engineering selection purposes.

Parameter Comparison

Engineering Selection Recommendations

For new designs requiring an active, production-supported RS232 2/2 transceiver in 20-SSOP packaging, the MAX3224CAP+ and MAX3224ECAP+ from Analog Devices Inc./Maxim Integrated are preferred substitutes. Both parts are in active production status and ROHS3 compliant, providing long-term supply assurance and regulatory alignment.

The ICL3225ECAZ from Renesas Electronics Corporation is an active alternative with MSL rating of 2 (1 Year), suitable for applications with standard moisture handling requirements. The ICL3222ECAZ offers active status with MSL 3 (168 Hours), requiring more stringent moisture control during storage and handling.

For legacy system maintenance where RoHS non-compliance is acceptable, the MAX3223CDB from Texas Instruments provides electrical equivalence, though it is obsolete. The ICL3223ECAZ is also obsolete and should not be selected for new applications.

Frequently Asked Questions (FAQ)

Q: Can MAX3224CAP+ and MAX3224ECAP+ be used interchangeably with MAX3384ECAP?

A: Yes. Both parts meet all electrical and mechanical specifications: 2/2 RS232 transceiver, 250kbps data rate, 3V to 5.5V supply, 0°C to 70°C operating range, and 20-SSOP package. The primary advantage is active production status and ROHS3 compliance.

Q: What is the difference between ICL3222ECAZ and ICL3225ECAZ?

A: Both are Renesas RS232 2/2 transceivers in 20-SSOP packaging with identical electrical specifications. The difference is moisture sensitivity level: ICL3222ECAZ is MSL 3 (168 Hours), while ICL3225ECAZ is MSL 2 (1 Year). ICL3225ECAZ requires less stringent moisture control and is preferred for standard applications.

Q: Why is the MAX3384ECAP marked as obsolete?

A: The MAX3384ECAP has been discontinued by Analog Devices Inc./Maxim Integrated. Active alternatives such as MAX3224CAP+ and MAX3224ECAP+ provide equivalent functionality with current production support.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. The original MAX3384ECAP is RoHS non-compliant. All listed substitutes except MAX3223CDB are ROHS3 compliant. For applications requiring RoHS compliance, select from MAX3224CAP+, MAX3224ECAP+, ICL3222ECAZ, ICL3223ECAZ, or ICL3225ECAZ.

Q: Does package compatibility guarantee pin-for-pin compatibility?

A: All listed parts use the 20-SSOP package with identical physical dimensions (0.209", 5.30mm Width). However, pin-for-pin compatibility must be verified against detailed pinout documentation for each manufacturer's datasheet before board-level substitution.
