ISL32435EIBZ

Overview

The ISL32435EIBZ is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device provides a data rate of 1 Mb/s with differential output types. It features 1 driver and 1 receiver in an 8-LD SOIC package. The component is rated for operation between -40°C and +85°C. It includes 40V overvoltage protection on the I/O pins and offers 15V common-mode rejection capabilities.

Feature Summary

• Integrated 40V overvoltage protection on input/output terminals for enhanced bus safety
• Supports full-duplex communication via RS-422 and RS-485 standards
• Operates reliably across extended industrial temperature ranges

Applications

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

Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's current datasheet to confirm pinout and packaging dimensions. Confirm RoHS compliance status directly with the supplier documentation. Check for any product change notices regarding assembly sites or material composition updates prior to finalizing procurement orders.

Selection Notes

Select this component when a single differential transceiver with high overvoltage tolerance is required. Ensure the system design accommodates the 8-pin SOIC footprint. Verify that the 1 Mb/s data rate meets the application's throughput requirements. Confirm power supply constraints align with the 3 V to 5.5 V operating range.

Part Context

This part belongs to the ISL32435E series of interface ICs. It is designed for robust communication in electrically noisy environments. The series typically integrates protection features to safeguard downstream circuitry from transient voltages common in industrial bus applications.

Replacement Considerations

Consult official substitution guides for equivalent single-channel RS-485 transceivers with similar overvoltage ratings. Verify pin compatibility before replacing. Generic alternatives may lack the specific 40V protection characteristics.
