ISL32493EIBZ-T7A

Overview

The ISL32493EIBZ-T7A is a high-speed RS-485 transceiver manufactured by Renesas Electronics. It supports data rates up to 10 Mbps and operates on a single 5 V supply. The device features overvoltage protection (OVP) on the bus pins, allowing operation with voltages up to ±60 V while maintaining communication integrity. It includes high electrostatic discharge (ESD) protection rated at ±15 kV HBM. The component is housed in a 14-lead SOIC package and is designed for industrial environments with an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed differential data transmission up to 10 Mbps
• Provides robust overvoltage protection on bus lines up to ±60 V
• Includes high-level ESD protection for harsh industrial environments

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check current lifecycle status as older Intersil/Renesas parts may have limited availability or obsolescence notices.

Selection Notes

Select this part for applications requiring high-speed RS-485 communication with significant bus voltage exposure risks. Ensure the system design accommodates the 14-lead SOIC footprint. Verify that the 5 V supply requirement aligns with the target power architecture.

Part Context

This component belongs to the ISL3249xE family of high-speed RS-485 transceivers. It shares core specifications with the ISL32493EIBZ but differs in packaging format. The series is characterized by its combination of speed and fault tolerance.

Replacement Considerations

Direct substitutes include the ISL32493EIBZ in tube packaging. Other compatible options within the same family should be evaluated based on pin compatibility and electrical parameter equivalence.
