MAX3158CAI+T

Overview

The MAX3158CAI+T is a low-power RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single +5V supply and supports data transfer rates up to 10Mbps. The device features a high common-mode rejection capability of 2kV, ensuring reliable communication in electrically noisy environments. It is housed in an SSOP-28 package and is designed for half-duplex data transmission over balanced differential lines.

Feature Summary

• High common-mode rejection ratio for noise immunity
• Low power consumption suitable for battery-operated systems
• Half-duplex operation with integrated driver and receiver

Applications

• Industrial automation control networks
• Building automation and security systems
• Point-to-point or multi-drop communication links

Procurement Notes

Verify the specific suffix 'CAI' against official datasheets to confirm temperature range and package details. Ensure compatibility with existing board layouts for the SSOP-28 footprint. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when a robust RS-485 interface is required for moderate-speed applications up to 10Mbps. Consider the 2kV common-mode rejection for environments with significant electrical interference. Verify that the half-duplex architecture aligns with the system's communication protocol requirements.

Part Context

This part belongs to the MAX3158 family of RS-485 transceivers. It shares functional similarities with other Maxim Integrated interface ICs but is distinct in its specific pinout and performance characteristics tailored for 5V systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX3158 series or similar RS-485 transceivers from Analog Devices. Ensure substitute parts meet the same voltage and speed specifications.
