ISL3155EIUZ-T

Overview

The ISL3155EIUZ-T is a single RS-485 transceiver manufactured by Renesas Electronics under the Intersil brand. It operates on a single 5 V supply and supports data rates up to 1 Mb/s. The device features high common-mode rejection and is designed for half-duplex communication. It complies with IEC 61000-4-2 electrostatic discharge standards, providing robust protection against ESD events. The component is housed in an MSOP-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• IEC 61000-4-2 compliant electrostatic discharge protection
• High common-mode noise rejection capability
• Low power consumption design

Applications

• Industrial automation control systems
• Building automation networks
• Metering applications requiring RS-485 connectivity

Procurement Notes

Verify the manufacturer date code and lot number upon receipt to ensure authenticity. Confirm that the packaging integrity remains intact to prevent moisture damage, as the component exhibits humidity sensitivity. Cross-reference the part marking with official Renesas documentation to validate the specific suffix and package type before integration into production lines.

Selection Notes

Select this component when a single half-duplex RS-485 interface is required with integrated ESD protection. Ensure the system voltage aligns with the specified 5 V operating range. Consider the MSOP-8 footprint constraints during PCB layout. Verify that the 1 Mb/s data rate meets the network timing requirements compared to higher-speed alternatives in the series.

Part Context

This part belongs to the ISL3155E family of RS-485 transceivers. The 'T' suffix indicates tape and reel packaging for automated assembly. The 'IUZ' designation specifies the MSOP-8 package variant. This series is engineered for reliable communication in electrically noisy industrial environments while maintaining low power usage.

Replacement Considerations

Direct pin-compatible substitutes within the same series include ISL3155EIBZ-T (SOIC-8 package) or ISL3155EIU. Verify package dimensions and thermal characteristics when substituting between MSOP and SOIC formats.
