ISL3156EIBZ-TR5453

Overview

The ISL3156EIBZ-TR5453 is a 5V RS-485/RS-422 differential transceiver manufactured by Renesas Electronics. It supports data rates up to 20 Mb/s and operates within an ambient temperature range of -40°C to +85°C. The device features IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It utilizes a 14-lead SOIC package and includes full fail-safe receiver functionality to ensure a high logic output when inputs are floating or shorted.

Feature Summary

• IEC 61000-4-2 ESD protection for robust operation in harsh environments
• Full fail-safe receiver design prevents false triggering on undriven buses
• Hot-plug capability maintains three-state outputs during power transitions

Applications

• Industrial automation control networks
• Building automation systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix TR5453 against official Renesas documentation to confirm reel specifications and tape-and-reel dimensions. Ensure the component matches the standard ISL3156E functional definition, as suffixes typically denote packaging variations rather than electrical changes. Cross-reference with authorized distributors to validate authenticity and traceability.

Selection Notes

Select this component for applications requiring high-speed communication up to 20 Mbps over RS-485 or RS-422 networks. It is suitable for designs needing integrated ESD protection without external components. Verify that the 5V supply voltage aligns with the system power architecture and that the SOIC-14 package fits the PCB layout constraints.

Part Context

This part belongs to the ISL3156E series of ruggedized RS-485/RS-422 transceivers. The series is characterized by its ability to operate reliably in electrically noisy industrial environments. It shares core architectural features with other members of the family, such as the ISL3152E and ISL3158E, differing primarily in pinout configurations and specific interface standards supported.

Replacement Considerations

Direct replacements include the ISL3156EIBZ and ISL3156EIBZ-T from Renesas. Other compatible devices in the broader RS-485/422 category may require verification of pin compatibility and electrical parameter alignment.
