MAX233CPP RS232 Transceiver Interface IC Equivalent & Substitute Parts

Part Overview

The MAX233CPP is a 2/2 full-duplex RS232 transceiver interface IC manufactured by Analog Devices Inc./Maxim Integrated in a 20-pin DIP package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement. The MAX233CPP operates within the 4.75V to 5.25V supply voltage range and supports RS232 protocol communication at 120 Kbps data rate with 500 mV receiver hysteresis across the 0°C to 70°C operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX233CPP is determined by strict parametric equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2
• Duplex: Full
• Data Rate: 120 Kbps
• Voltage - Supply: 4.75V ~ 5.25V
• Mounting Type: Through Hole
• Package / Case: 20-DIP (0.300", 7.62mm)
• Supplier Device Package: 20-PDIP

Substitute Categories:

Parametric Equivalents (MAX203 and MAX233 Series): Parts MAX203CPP+G36, MAX203ECPP+G36, MAX233ACPP+G36, and MAX233CPP+G36 maintain identical electrical specifications and physical packaging to the MAX233CPP. These parts differ only in product status (Active vs. Obsolete) and RoHS compliance certification (ROHS3 Compliant vs. RoHS non-compliant). All four parts share the same 500 mV receiver hysteresis specification.

Manufacturer Recommended Alternatives (ADM233 Series): Parts ADM233LANZ and ADM233LJNZ are manufacturer-recommended substitutes from Analog Devices Inc. These parts maintain full parametric compatibility with the MAX233CPP across protocol, driver/receiver configuration, duplex mode, data rate, supply voltage, and package specifications. The ADM233 series differs in receiver hysteresis (650 mV vs. 500 mV) and operating temperature range specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): MAX233ACPP+G36 and MAX233CPP+G36 provide direct functional equivalence to the MAX233CPP with the advantage of Active product status and ROHS3 compliance. These parts maintain the original MAX233 base product number and are suitable for applications requiring exact parametric matching.

For Extended Temperature Range Applications: ADM233LANZ extends the operating temperature range to -40°C ~ 85°C while maintaining all other electrical specifications. This part is appropriate for designs requiring enhanced thermal performance beyond the standard 0°C ~ 70°C range.

For Standard Operating Conditions: ADM233LJNZ maintains the 0°C ~ 70°C operating temperature specification of the MAX233CPP while offering Active product status and ROHS3 compliance. The 650 mV receiver hysteresis specification provides enhanced noise immunity compared to the 500 mV specification of the MAX233CPP.

For MAX203 Base Product Compatibility: MAX203CPP+G36 and MAX203ECPP+G36 are functionally equivalent alternatives from the MAX203 product line, offering Active status and ROHS3 compliance. These parts are suitable for applications where MAX203 base product designation is acceptable.

All substitute parts maintain identical packaging, mounting type, and electrical protocol specifications. Product status transition from Obsolete to Active and RoHS compliance certification are the primary differentiators among substitute options.

Frequently Asked Questions (FAQ)

Q: Can MAX233ACPP+G36 be used as a direct replacement for MAX233CPP? A: Yes. MAX233ACPP+G36 maintains identical electrical specifications, package configuration, and functional characteristics. The primary differences are product status (Active vs. Obsolete) and RoHS compliance certification (ROHS3 Compliant vs. RoHS non-compliant).

Q: What is the difference between the MAX233 and MAX203 substitute options? A: Both MAX233 and MAX203 series parts meet the parametric requirements for substitution. The primary distinction is the base product number designation. MAX233ACPP+G36 and MAX233CPP+G36 retain the MAX233 base product number, while MAX203CPP+G36 and MAX203ECPP+G36 use the MAX203 base product number. All four parts are functionally equivalent for RS232 2/2 transceiver applications.

Q: How do the ADM233 parts differ from the MAX233/MAX203 options? A: ADM233LANZ and ADM233LJNZ are manufacturer-recommended alternatives from Analog Devices Inc. The ADM233 series specifies 650 mV receiver hysteresis compared to 500 mV in the MAX233CPP. ADM233LANZ offers an extended operating temperature range of -40°C ~ 85°C, while ADM233LJNZ maintains the standard 0°C ~ 70°C range. All other electrical and physical specifications remain equivalent.

Q: Are all substitute parts available in the same 20-DIP package? A: Yes. All substitute parts listed are packaged in 20-DIP (0.300", 7.62mm) configuration with 20-PDIP supplier device package designation, ensuring direct physical compatibility with the MAX233CPP footprint.

Q: What is the significance of the +G36 suffix in part numbers? A: The +G36 suffix indicates packaging specification and tape/reel configuration. Parts with this suffix are supplied in Tube packaging format. This designation does not affect electrical functionality or compatibility.

Q: Which substitute part should be selected for new designs? A: For new designs, selection should prioritize Active product status and ROHS3 compliance. MAX233ACPP+G36, MAX233CPP+G36, MAX203CPP+G36, MAX203ECPP+G36, ADM233LANZ, and ADM233LJNZ all meet these criteria. Selection between these options depends on specific application requirements regarding receiver hysteresis specification and operating temperature range.

Q: Is the receiver hysteresis difference between 500 mV and 650 mV significant for substitution? A: Receiver hysteresis affects noise immunity and signal transition characteristics. The 650 mV specification in ADM233 parts provides enhanced noise margin compared to the 500 mV specification in MAX233CPP and MAX203 parts. This difference is functionally compatible for standard RS232 applications but should be considered in noise-sensitive environments.
