ISL31490EIUZ-T

Overview

The ISL31490EIUZ-T is a fault-protected, 5V-powered differential transceiver designed for RS-485 and RS-422 balanced communication. It features an extended common mode range of ±25V and bus pin protection up to ±60V. The device operates in full-duplex mode with data rates up to 0.25Mbps. It supports a supply voltage range of 4.5V to 5.5V and includes low quiescent current of 2.3mA and ultra-low shutdown current of 10µA. The component utilizes a 10-lead MSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Bus pins protected against faults up to ±60V
• Extended common mode range of ±25V
• Full fail-safe receiver design
• Hot plug circuitry

Applications

• Utility meters/automated meter reading systems
• High node count systems
• PROFIBUS™ and field bus networks
• Security camera networks
• Building lighting and environmental control systems

Procurement Notes

Verify the specific ordering suffix '-T' indicates tape and reel packaging as per manufacturer documentation. Confirm the 'E' designation aligns with the intended RoHS compliance requirements. Ensure the 10-lead MSOP package dimensions match the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this part for applications requiring robust fault protection and extended common mode voltage tolerance. Verify that the full-duplex configuration meets system communication needs. Check if the 0.25Mbps data rate is sufficient or if higher speed variants are required. Ensure the 10-lead MSOP package fits the available board space.

Part Context

This component belongs to the ISL3149xE family of fault-protected transceivers from Renesas Electronics. It shares core electrical characteristics with other members like the ISL31491E and ISL31492E but differs in duplex configuration and pin count. The EIUZ suffix specifically denotes the 10-lead MSOP package variant.

Replacement Considerations

Refer to the ISL32490E series datasheet for exact replacements. Consider the ISL31491E or ISL31493E if different pin counts or data rates are acceptable.
