ISL31495EIUZ-T

Overview

The ISL31495EIUZ-T 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 range of ±25V. It includes full fail-safe receiver design, hot plug circuitry, and low power shutdown capability with a typical quiescent current of 2.3mA. Packaged in an 8-lead MSOP format, it functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Fault protected RS-485 bus pins withstand up to ±60V
• Extended common mode range operating up to ±25V
• Full fail-safe receiver design for open, short, or terminated bus conditions
• Hot plug circuitry maintains three-state outputs during power transitions

Applications

• Utility meters and automated meter reading systems
• High node count communication networks
• PROFIBUS and field bus networks
• Industrial process control systems

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tape and reel packaging specifications. Ensure the component matches the required package type and temperature grade for your application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring robust fault protection and extended common mode voltage tolerance. Verify that the half-duplex configuration aligns with your network topology requirements and that the 1Mbps data rate meets your bandwidth needs.
