ISL32475EIBZ-T7A

Overview

The ISL32475EIBZ-T7A is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates at data rates up to 1 Mb/s and requires a fixed 5 V supply voltage. The device features overvoltage protection on the bus pins, supporting common-mode voltages of +/-15 V. It includes high differential receiver sensitivity and ESD protection. The component functions within an operating temperature range of -40°C to +85°C. It is housed in an 8-lead SOIC package with a shutdown feature and draws 2.3 mA of operating current.

Feature Summary

• Integrated overvoltage protection for robust bus interface performance
• High common-mode rejection capability for noise immunity
• Low power consumption with dedicated shutdown mode

Applications

• Industrial communication networks requiring RS-485 connectivity
• Building automation systems utilizing RS-422 protocols
• Data acquisition modules in harsh electrical environments

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Check humidity sensitivity level handling procedures before assembly. Validate package marking against official datasheet specifications to prevent counterfeit substitution.

Selection Notes

Select this part when a 5 V only supply system requires 1 Mb/s transmission speeds. Choose this component if +/-15 V common-mode protection is mandatory for the application bus. Consider the 8-SOIC footprint constraints and thermal characteristics during PCB layout planning.

Part Context

This component belongs to the ISL32475E series of high-performance interface transceivers. It represents a specialized variant designed specifically for 5 V operation with enhanced overvoltage tolerance. The product line focuses on reliable serial communication in industrial settings.

Replacement Considerations

The ISL32475EIBZ is listed as a manufacturer-recommended alternative. Verify pin compatibility and electrical parameters before substitution. Ensure the non-tape version meets packaging requirements for the target assembly process.
