MAX3158EPI

Overview

The MAX3158EPI is an isolated RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 25Mbps. The device features a high common-mode rejection ratio (CMRR) of ±60V, ensuring reliable communication in electrically noisy environments. It is housed in a 28-pin PDIP package with through-hole mounting capabilities.

Feature Summary

• Integrated isolation capability for robust signal transmission
• High common-mode rejection ratio for noise immunity
• Supports standard RS-485 and RS-422 communication protocols

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix 'EPI' corresponds to the 28-pin PDIP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component matches the required operating temperature range of -40°C to 85°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component when isolated RS-485/RS-422 communication is required in through-hole PCB designs. Consider the 25Mbps data rate limit and ±60V CMRR specifications against system requirements. Evaluate the need for integrated isolation versus external solutions based on board space and cost constraints.

Part Context

This part belongs to the MAX3158 series of isolated transceivers. It complements other interface ICs from Maxim Integrated designed for harsh industrial environments. The EPI designation specifically indicates the plastic dual in-line package format suitable for prototyping and durable assembly.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX3158 family. Verify that alternative parts maintain the same isolation voltage ratings and package dimensions. Consult official cross-reference guides for updated availability if the current model is discontinued.
