MAX3158EAI+T

Overview

The MAX3158EAI+T is an RS-422/RS-485 interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a high common-mode rejection ratio (CMRR) and supports a 60V input range on the bus lines. The device is housed in a 28-pin SSOP package and operates within a temperature range of -40°C to +85°C. It belongs to the MAX3158 series and is classified under RS-422/RS-485 Interface ICs. The component utilizes a reel packaging format for surface mount installation.

Feature Summary

• High common-mode rejection ratio for noise immunity
• Supports 60V input range on bus lines
• RS-422/RS-485 compatible transceiver functionality

Applications

• Industrial communication networks
• Building automation systems
• Process control applications

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm current supply availability as stock levels may be restricted. Ensure the SSOP-28 package footprint matches the design requirements. Check for any recent product change notices that might affect long-term availability or pin compatibility.

Selection Notes

Select this component when high noise immunity is required in RS-485 environments. The 60V bus tolerance provides protection against transient voltage spikes. Verify that the SSOP-28 package size fits the PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the target application.

Part Context

This part is part of the Maxim Integrated RS-485 transceiver family, designed for robust data transmission in electrically noisy environments. The MAX3158 series emphasizes reliability through enhanced common-mode rejection capabilities. It serves as a key interface solution for connecting microcontrollers to multi-drop bus networks in industrial settings.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX3158 series. Verify if alternative RS-485 transceivers from other manufacturers offer compatible electrical characteristics and package dimensions. Ensure any substitute maintains the same 60V bus tolerance and CMRR specifications.
