MAX234EPE Equivalent & Substitute Parts

Part Overview

The MAX234EPE is a 4/0 RS232 driver interface IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin DIP package. This component functions as a line driver for RS232 serial communication protocols, supporting data rates up to 120 Kbps. The MAX234EPE is classified as obsolete, which necessitates identification of active equivalent parts to ensure continued design support and procurement availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX234EPE is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Driver/receiver configuration: 4/0
• Data rate capability: 120 Kbps minimum
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 16-DIP (0.300", 7.62mm)
• Mounting technology: Through Hole

The MAX234EPE+ is identified as a direct substitute based on identical electrical specifications, mechanical compatibility, and functional equivalence across all specified parameters. The primary distinction is product status and regulatory compliance, with the MAX234EPE+ classified as active and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

The MAX234EPE+ is the direct equivalent for the obsolete MAX234EPE. Selection of the MAX234EPE+ is supported by:

• Identical electrical and mechanical specifications across all functional parameters
• Active product status ensuring long-term availability and supply chain continuity
• RoHS3 compliance, meeting current environmental and regulatory requirements for new designs and manufacturing processes
• Equivalent moisture sensitivity classification and REACH status
• Pin-compatible 16-PDIP package enabling direct board-level substitution without layout modifications

For applications currently using the MAX234EPE, transition to the MAX234EPE+ is a direct replacement with no functional or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the MAX234EPE+ be used as a direct replacement for the MAX234EPE?
