MAX214EWI RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX214EWI is a full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, configured with 3 drivers and 5 receivers in a 28-SOIC surface mount package. This interface IC operates across the 4.5V to 5.5V supply voltage range with a maximum data rate of 116 Kbps and supports operating temperatures from -40°C to 85°C.

The MAX214EWI carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for systems utilizing this transceiver architecture.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX214EWI is determined by strict equivalence across the following critical parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 3/5 configuration
• Duplex Mode: Full
• Receiver Hysteresis: 500 mV
• Data Rate: 116 Kbps minimum
• Supply Voltage Range: 4.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 28-SOIC form factor
• Mounting Type: Surface Mount

The MAX214EWI+ meets all electrical and mechanical parameters required for direct substitution. Both parts share identical base product architecture (MAX214 series), functional specifications, and physical packaging, ensuring pin-compatible and functionally equivalent operation in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The MAX214EWI+ is the direct substitute for the obsolete MAX214EWI. Both parts are electrically and mechanically identical across all functional parameters, with pin-compatible 28-SOIC packaging enabling direct board-level replacement without circuit modification.

The MAX214EWI+ carries an active product status, ensuring ongoing availability and supply chain support. Additionally, the MAX214EWI+ meets ROHS3 compliance requirements, providing environmental and regulatory advantages over the non-compliant original part. Both parts maintain identical moisture sensitivity classification (MSL 1) and REACH unaffected status.

Selection of the MAX214EWI+ is appropriate for new designs, production continuity, and retrofit applications requiring RS232 transceiver functionality with 3/5 driver/receiver configuration in the 28-SOIC package.

Frequently Asked Questions (FAQ)

Q: Can the MAX214EWI+ be used as a direct replacement for the MAX214EWI?

A: Yes. The MAX214EWI+ is electrically and mechanically equivalent to the MAX214EWI. Both parts feature identical RS232 transceiver specifications, 3/5 driver/receiver configuration, 500 mV receiver hysteresis, 116 Kbps data rate, 4.5V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and 28-SOIC package geometry. Pin-for-pin compatibility enables direct substitution without circuit redesign.

Q: What is the primary difference between the MAX214EWI and MAX214EWI+?

A: The MAX214EWI+ is the active production variant with ROHS3 compliance, while the MAX214EWI is obsolete and RoHS non-compliant. Functionally and electrically, both parts are identical. The MAX214EWI+ is recommended for all new applications and ongoing production.

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

A: No. Both the MAX214EWI and MAX214EWI+ use identical 28-SOIC surface mount packaging with 0.295" (7.50mm) width. No PCB layout modifications are required for substitution.

Q: What certifications and compliance standards apply to the MAX214EWI+?

A: The MAX214EWI+ is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification and HTSUS code 8542.39.0001. Moisture sensitivity level is MSL 1 (unlimited).

Q: Is the MAX214EWI+ suitable for designs requiring RoHS compliance?

A: Yes. The MAX214EWI+ meets ROHS3 compliance requirements, making it appropriate for applications with environmental and regulatory mandates. The original MAX214EWI is RoHS non-compliant and should not be used in RoHS-restricted applications.
