MAX206ENG RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX206ENG is a 4/3 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 24-DIP package. This component is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support. The MAX206ENG provides four drivers and three receivers with full RS232 protocol compliance, operating across the industrial temperature range of -40°C to 85°C. Due to its obsolete status, sourcing active alternatives with matching electrical and mechanical specifications is necessary for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX206ENG is determined by strict equivalence across the following critical parameters:

• Protocol & Transceiver Configuration: RS232 protocol with 4/3 driver/receiver configuration and full-duplex operation
• Electrical Performance: Supply voltage range 4.5V ~ 5.5V, operating temperature -40°C ~ 85°C, receiver hysteresis tolerance, and data rate capability
• Physical Form Factor: 24-DIP package with 0.300" (7.62mm) pitch and 24-PDIP supplier packaging
• Mounting Technology: Through-hole mounting compatibility

The identified substitutes maintain these core parameters while offering improved product status (Active vs. Obsolete) and enhanced compliance certifications. Receiver hysteresis variations within the RS232 specification range do not preclude functional equivalence in standard applications.

Engineering Selection Recommendations

MAX236ENG+ (Parametric Equivalent)

The MAX236ENG+ is the primary substitute for the MAX206ENG. Both parts maintain identical electrical specifications including receiver hysteresis (500 mV), data rate (120 Kbps), supply voltage range (4.5V ~ 5.5V), and operating temperature (-40°C ~ 85°C). The MAX236ENG+ offers Active product status compared to the Obsolete classification of the MAX206ENG, ensuring long-term availability. Additionally, the MAX236ENG+ achieves ROHS3 compliance, addressing regulatory requirements for new designs. Physical form factor and pinout compatibility are maintained across both 24-DIP packages.

ADM206ANZ (Direct Manufacturer Alternative)

The ADM206ANZ provides an alternative from Analog Devices Inc. with identical driver/receiver configuration (4/3), protocol (RS232), supply voltage (4.5V ~ 5.5V), and operating temperature range (-40°C ~ 85°C). The ADM206ANZ features a higher receiver hysteresis specification (650 mV) compared to the MAX206ENG (500 mV), which remains within RS232 standard tolerances and does not compromise functional compatibility. The ADM206ANZ is Active status with ROHS3 compliance. The 24-DIP package and through-hole mounting are identical to the original part.

Frequently Asked Questions (FAQ)

Q: Can MAX236ENG+ be used as a direct replacement for MAX206ENG in existing designs?

A: Yes. The MAX236ENG+ maintains identical electrical specifications (receiver hysteresis, data rate, supply voltage, operating temperature) and physical form factor (24-DIP package). Pin-for-pin compatibility is preserved. The primary difference is product status (Active vs. Obsolete) and improved RoHS compliance.

Q: What is the significance of the receiver hysteresis difference between MAX206ENG (500 mV) and ADM206ANZ (650 mV)?

A: Both values fall within RS232 specification tolerances. The higher hysteresis in the ADM206ANZ provides increased noise immunity in the receiver input stage. This difference does not affect functional compatibility in standard RS232 communication applications.

Q: Are there any package or pinout differences between the three parts?

A: No. All three parts use identical 24-DIP (0.300", 7.62mm) packages with 24-PDIP supplier packaging. Through-hole mounting is consistent across all variants.

Q: Why is the MAX206ENG classified as Obsolete?

A: The MAX206ENG has reached end-of-life status from the manufacturer. Active alternatives (MAX236ENG+ and ADM206ANZ) are available with equivalent or superior specifications and compliance certifications.

Q: Does the transition from RoHS non-compliant to ROHS3 compliant affect circuit operation?

A: No. RoHS compliance relates to material composition and manufacturing processes, not electrical performance. ROHS3 compliance in the MAX236ENG+ and ADM206ANZ ensures compatibility with modern procurement and environmental regulations without altering functional behavior.

Q: What is the data rate specification for ADM206ANZ?

A: The data rate for ADM206ANZ is not specified in the available documentation. However, the part maintains the same 4/3 transceiver configuration, supply voltage, and operating temperature as the MAX206ENG, supporting standard RS232 communication protocols.
