ISL3158EIBZ-T

Overview

The ISL3158EIBZ-T is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates with a fixed supply voltage of 5 V and supports data rates up to 12 Mb/s. The device features one driver and one receiver, housed in an SOIC-8 surface-mount package. It functions within a temperature range of -40°C to +85°C. Key electrical characteristics include high output voltage (VOD) for improved noise immunity and compliance with IEC 61000 ESD standards. The component is designed for half-duplex differential communication applications.

Feature Summary

• IEC 61000-compliant electrostatic discharge protection
• High output voltage capability for robust signal transmission
• Slew-rate limited drivers to minimize electromagnetic interference

Applications

• Industrial automation control systems
• Building automation networks
• Data communication interfaces requiring RS-485/RS-422 compliance

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure moisture sensitivity level requirements are met during storage and handling procedures. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component for designs requiring 12 Mb/s data throughput on RS-485 or RS-422 buses. It is suitable for environments demanding high ESD immunity without external protection components. Consider the SOIC-8 footprint for space-constrained PCB layouts. Verify that the 5 V supply voltage aligns with the system power architecture.

Part Context

This part belongs to the ISL3158E series of ruggedized transceivers. It shares the SOIC-8 package and 5 V operation with related models like the ISL3152E and ISL3155E. The primary distinction lies in its higher 12 Mb/s data rate compared to lower-speed variants in the same family.

Replacement Considerations

Direct functional substitutes within the same series include ISL3152EIBZ-T and ISL3155EIBZ-T, though data rates differ. Verify pin compatibility and electrical specifications before substitution.
