ISL31496EIUZ-T

Overview

The ISL31496EIUZ-T is a full-duplex, fault-protected 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 15Mbps. The device features an extended common mode range of ±25V and bus pin protection against faults up to ±60V. It utilizes a 10-lead MSOP package with an operating temperature range from -40°C to +85°C.

Feature Summary

• Full fail-safe receiver design ensures logic high output when inputs are floating, shorted, or on an idle bus.
• Hot plug circuitry maintains three-state outputs during power-up and power-down events.
• High transient overvoltage tolerance provides robustness against electrical disturbances.

Applications

• Utility meters and automated meter reading systems
• PROFIBUS and field bus networks
• Security camera networks
