MAX3388EEUG Equivalent & Substitute Parts

Part Overview

The MAX3388EEUG is a full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, configured with 3 drivers and 2 receivers in a 24-TSSOP surface mount package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new design implementations. The part operates across a 3V to 5.5V supply range with a maximum data rate of 460 Kbps and is suitable for industrial and commercial RS232 communication applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3388EEUG is determined by strict equivalence across the following critical parameters:

• Protocol and Configuration: RS232 full-duplex transceiver with 3 drivers and 2 receivers
• Electrical Performance: 460 Kbps data rate, 700 mV receiver hysteresis, 3V to 5.5V supply voltage range
• Operating Environment: -40°C to 85°C temperature range
• Physical Form Factor: 24-TSSOP surface mount package with 0.173" width (4.40mm)

The MAX3388EEUG+ meets all these criteria and is therefore classified as a parametric equivalent. The primary distinction between the main part and its substitute is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX3388EEUG+ is the direct parametric equivalent for the obsolete MAX3388EEUG. Selection of the substitute part is justified on the following grounds:

• Functional Equivalence: All electrical, timing, and operational parameters are identical across both parts
• Active Product Status: The MAX3388EEUG+ maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The MAX3388EEUG+ achieves ROHS3 compliance, whereas the original part is non-compliant, making the substitute suitable for applications subject to environmental regulations
• Package Compatibility: Both parts utilize the identical 24-TSSOP form factor, enabling direct PCB layout compatibility without redesign

For applications currently using the MAX3388EEUG, transition to the MAX3388EEUG+ requires no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can the MAX3388EEUG+ be used as a direct replacement for the MAX3388EEUG?

A: Yes. The MAX3388EEUG+ is a parametric equivalent with identical electrical specifications, data rate, supply voltage range, operating temperature range, and 24-TSSOP package dimensions. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The MAX3388EEUG is obsolete with RoHS non-compliant status, while the MAX3388EEUG+ is an active product with ROHS3 compliance. All functional and electrical parameters remain unchanged.

Q: Are there any package or pinout differences?

A: No. Both parts are housed in the 24-TSSOP package with identical pin assignments and mechanical dimensions (0.173" width, 4.40mm).

Q: Is the MAX3388EEUG+ suitable for new designs?

A: Yes. The active product status and ROHS3 compliance make the MAX3388EEUG+ the appropriate choice for new RS232 transceiver implementations requiring 3 drivers and 2 receivers in a 24-TSSOP package.

Q: What are the key substitution criteria for this part family?

A: Substitution is valid when the following parameters match: RS232 protocol, 3/2 driver/receiver configuration, full-duplex operation, 460 Kbps data rate, 3V to 5.5V supply voltage, -40°C to 85°C operating temperature, and 24-TSSOP surface mount package.
