MAX236ENG RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX236ENG is a 4/3 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 24-pin DIP package. This interface IC is designed for serial communication applications requiring RS232 protocol compliance. The MAX236ENG is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX236ENG is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 protocol requirement
• Channel Configuration: 4 drivers and 3 receivers (4/3 architecture)
• Duplex Operation: Full-duplex capability
• Electrical Characteristics: Receiver hysteresis of 500 mV, data rate of 120 Kbps, supply voltage range of 4.5V ~ 5.5V
• Thermal Performance: Operating temperature range of -40°C ~ 85°C
• Physical Form Factor: 24-pin DIP package with 0.300" (7.62mm) pitch for through-hole mounting

The MAX236ENG+ qualifies as a parametric equivalent based on identical electrical and mechanical specifications. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX236ENG+ is the direct parametric equivalent for the obsolete MAX236ENG. Both parts share identical electrical specifications and mechanical form factors, enabling pin-for-pin replacement in existing designs.

Product Status Consideration: The MAX236ENG is classified as obsolete, while the MAX236ENG+ maintains active product status with ongoing manufacturer support and availability.

Compliance Advantage: The MAX236ENG+ achieves ROHS3 compliance, whereas the original MAX236ENG is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the MAX236ENG+ is the appropriate selection.

Packaging: The MAX236ENG+ is supplied in tube packaging, compared to standard packaging for the original part. This distinction affects handling and storage but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MAX236ENG+ directly replace the MAX236ENG in existing designs?

A: Yes. The MAX236ENG+ is a parametric equivalent with identical electrical specifications, channel configuration (4/3), duplex mode, receiver hysteresis, data rate, supply voltage range, operating temperature range, and 24-pin DIP package form factor. Direct pin-for-pin replacement is supported.

Q: What is the primary reason to transition from MAX236ENG to MAX236ENG+?

A: The MAX236ENG is obsolete with no ongoing manufacturer support. The MAX236ENG+ is an active product with current availability. Additionally, the MAX236ENG+ achieves ROHS3 compliance, addressing regulatory requirements not met by the original part.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical RS232 protocol compliance, 4/3 driver/receiver configuration, 500 mV receiver hysteresis, 120 Kbps data rate, 4.5V ~ 5.5V supply voltage range, and -40°C ~ 85°C operating temperature range.

Q: Does the tube packaging of MAX236ENG+ affect compatibility?

A: No. Packaging format is a supply and handling consideration only. The tube packaging does not alter electrical performance, mechanical dimensions, or pin configuration. The 24-pin DIP package specifications remain identical.

Q: What compliance certifications apply to each part?

A: The MAX236ENG is RoHS non-compliant and REACH unaffected. The MAX236ENG+ is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification and HTSUS code 8542.39.0001.
