ISL3155EIBZ-T

Overview

The ISL3155EIBZ-T is a single half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 1 Mb/s. The device features an SOIC-8 surface-mount package with an operating temperature range from -40°C to +85°C. Key electrical characteristics include differential outputs, IEC6100 ESD protection, and high output voltage drivers designed for robust communication in noisy industrial environments.

Feature Summary

• Integrated IEC6100 electrostatic discharge protection for enhanced signal integrity
• High output voltage capability ensures reliable transmission over long bus distances
• 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 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the component matches the exact part number to avoid pinout or functional mismatches during integration.

Selection Notes

Select this component for applications requiring standard 5V operation with moderate data rates. It is suitable for designs needing built-in ESD protection without external components. Consider alternative models if higher data speeds or lower voltage supplies are required for the specific system architecture.

Part Context

This part belongs to the ISL315xE series of interface ICs from Renesas. The series focuses on providing ruggedized communication solutions for harsh environments. The ISL3155 variant specifically targets half-duplex applications requiring high noise immunity and simple interface requirements.

Replacement Considerations

ISL3155EIBZ is a tube-packaged equivalent. Verify package compatibility and moisture sensitivity levels before substitution.
