ISL31495EIBZ

Overview

The ISL31495EIBZ is a half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 1Mbps. The device features ±60V fault protection on bus pins and an extended common mode voltage range of ±25V. It utilizes an 8-lead SOIC package with an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated fault protection for RS-485 bus pins against voltages up to ±60V
• Extended common mode voltage tolerance exceeding standard RS-485 requirements
• Full fail-safe receiver design ensuring logic high output during idle or floating states
• Hot plug circuitry maintaining three-state outputs during power transitions

Applications

• Utility meters and automated meter reading systems
• PROFIBUS and field bus networks in factory automation
• Security camera networks
• Building lighting and environmental control systems
• Industrial process control networks

Procurement Notes

Verify the specific ordering suffix 'BZ' corresponds to the 8-lead SOIC package configuration when sourcing components. Confirm that the procurement documentation explicitly references the FN7637 datasheet revision 3.00 to ensure alignment with the manufacturer's current specifications and RoHS compliance status.

Selection Notes

Select this component for designs requiring robust fault protection and wide common mode voltage tolerance. Ensure the application utilizes a half-duplex architecture compatible with the multiplexed driver and receiver pins. Verify that the system power supply remains strictly within the 4.5V to 5.5V operational limits defined in the recommended operating conditions.

Part Context

This part belongs to the ISL3149xE series, which includes variants supporting different data rates and duplex configurations. The ISL31495EIBZ specifically provides a cost-effective solution for standard baud rate applications requiring enhanced noise immunity and bus protection compared to basic RS-485 transceivers.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify thermal resistance values and package dimensions when substituting with other manufacturers' devices to ensure mechanical fit.
