MAX3320AEAP Equivalent & Substitute Parts

Part Overview

The MAX3320AEAP 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 300mV receiver hysteresis, designed for serial communication applications requiring bidirectional RS232 signal conversion.

The MAX3320AEAP carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3320AEAP is determined by strict parametric equivalence across the following critical criteria:

Mandatory Matching Parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2
• Duplex: Full
• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply: 3V ~ 5.5V
• Data Rate: 250kbps
• Receiver Hysteresis: 300 mV
• Operating Temperature: -40°C ~ 85°C

All identified substitute parts meet these parameters without exception. Substitutes are grouped into two categories: active Analog Devices variants (MAX3320BEAP+, MAX3320TEAP+) and cross-manufacturer equivalents (ICL3223IAZ from Renesas Electronics Corporation).

Parameter Comparison

Engineering Selection Recommendations

MAX3320BEAP+ and MAX3320TEAP+ are direct Analog Devices variants of the obsolete MAX3320AEAP. Both parts maintain identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. These represent the primary substitution path for designs currently using the MAX3320AEAP, with the advantage of remaining within the same manufacturer ecosystem.

ICL3223IAZ from Renesas Electronics Corporation is a parametric equivalent that meets all functional and mechanical requirements. This cross-manufacturer substitute provides an alternative supply source and active product status. The ICL3223IAZ carries a Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), compared to MSL 1 (Unlimited) for the Analog Devices variants. This difference requires consideration in storage and handling protocols but does not affect electrical performance or functional compatibility.

All three substitute parts are ROHS3 compliant and REACH unaffected, supporting modern regulatory requirements that the obsolete MAX3320AEAP does not meet.

Frequently Asked Questions (FAQ)

Q: Can MAX3320BEAP+ and MAX3320TEAP+ be used interchangeably with MAX3320AEAP?

A: Yes. Both parts are parametrically equivalent to the MAX3320AEAP across all critical electrical and mechanical parameters: RS232 protocol, 2/2 driver/receiver configuration, full-duplex operation, 20-SSOP package, 3V to 5.5V supply range, 250kbps data rate, 300mV receiver hysteresis, and -40°C to 85°C operating temperature. The primary differences are product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What is the difference between MAX3320BEAP+ and MAX3320TEAP+?

A: Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package configuration. The difference lies in packaging format: MAX3320BEAP+ is supplied in Tube packaging, while MAX3320TEAP+ is also supplied in Tube packaging. Both are active products with ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Can ICL3223IAZ replace MAX3320AEAP in all applications?

A: ICL3223IAZ meets all parametric requirements for functional substitution. However, the Moisture Sensitivity Level (MSL) rating differs: ICL3223IAZ carries MSL 3 (168 Hours), while MAX3320AEAP carries MSL 1 (Unlimited). This requires stricter moisture control during storage and handling. Applications with standard moisture management practices will experience no functional impact.

Q: Are there any compliance differences between the substitute parts?

A: The MAX3320AEAP is RoHS non-compliant. All three substitute parts (MAX3320BEAP+, MAX3320TEAP+, and ICL3223IAZ) are ROHS3 compliant. All four parts are REACH unaffected. For applications subject to RoHS or REACH regulations, the substitute parts provide regulatory alignment that the original part does not.

Q: What inventory levels are available for each substitute?

A: Current inventory levels are: MAX3320BEAP+ (624 Pcs), MAX3320TEAP+ (953 Pcs), and ICL3223IAZ (1416 Pcs). These quantities support immediate procurement for design transitions or production requirements.
