ISL31475EIBZ

Overview

The ISL31475EIBZ is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 20 Mb/s. The device features an SOIC-8 surface-mount package with eight pins. It functions across an extended temperature range from -40°C to +85°C. Key electrical characteristics include a shutdown current of 1 µA and a receiver input threshold of ±200 mV. The component integrates overvoltage protection on the bus lines.

Feature Summary

• Supports high-speed data transmission up to 20 Mb/s for demanding industrial applications.
• Provides robust fault protection against short circuits and overvoltage conditions on differential bus lines.
• Incorporates low-power shutdown mode to minimize energy consumption during idle periods.

Applications

• Industrial automation control systems requiring reliable serial communication.
• Building automation networks utilizing RS-485 multi-drop configurations.
• Metering infrastructure for utility data collection and monitoring.

Procurement Notes

Verify the specific suffix 'BZ' indicates lead-free RoHS compliance when sourcing. Confirm the manufacturer designation as Renesas or Intersil, as legacy branding may appear on older documentation. Ensure the package type matches the required SOIC-8 footprint for PCB layout compatibility.

Selection Notes

Select this component for designs requiring high-speed RS-485 communication in harsh environments. It is suitable for applications needing integrated overvoltage protection without external components. Consider the 3 V to 5.5 V operating range for flexibility in power supply design.

Part Context

This part belongs to the ISL3147xE series of RS-422/RS-485 interface ICs. The series is characterized by high-speed operation and enhanced fault protection capabilities. It serves as a solution for reliable half-duplex data transmission in noisy industrial settings.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the ISL31472EIBZ and ISL31495EIBZ. Verify that alternative parts maintain the 20 Mb/s speed rating and identical SOIC-8 packaging constraints.
