MAX3158CPI

Overview

The MAX3158CPI is a low-power RS-422/RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 10Mbps. The device features a high common-mode rejection capability of 15kV and includes thermal shutdown protection for enhanced reliability. It is housed in a 28-pin Plastic Small Outline (PSOP) package, suitable for industrial applications requiring robust differential communication interfaces.

Feature Summary

• Supports RS-422 and RS-485 communication standards with full-duplex operation
• Provides high common-mode rejection to ensure signal integrity in noisy environments
• Integrates thermal shutdown circuitry to protect against overheating conditions

Applications

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

Procurement Notes

Verify the specific suffix 'CPI' against official datasheets to confirm package type and temperature range. Ensure compatibility with system voltage levels and interface requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing systems requiring reliable RS-422/RS-485 communication over moderate distances. Consider the 28-pin PSOP package constraints for PCB layout. Evaluate power consumption requirements against the 3.0V to 5.5V operating range to ensure efficient system design.

Part Context

This part belongs to the MAX3158 family of high-performance transceivers designed for demanding industrial environments. It complements other Maxim Integrated interface solutions by offering a balance of speed, power efficiency, and noise immunity for serial communication applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX3158 series or similar RS-485 transceivers from Analog Devices. Verify that any substitute maintains the same voltage range, data rate, and package dimensions to ensure seamless integration.
