ISL32470EIBZ-T

Overview

The ISL32470EIBZ-T is a single full-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 5 V supply and supports data rates up to 10 Mbps. The device features overvoltage protection (OVP) on both the transmitter input and receiver output, allowing safe operation with voltages exceeding the supply rail. It includes high electrostatic discharge (ESD) protection capabilities. The component is housed in a 14-lead SOIC package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides overvoltage protection on transmitter inputs and receiver outputs to withstand voltage faults beyond the supply rail.
• Delivers high ESD protection performance to ensure reliability in electrically noisy industrial environments.
• Supports full-duplex communication compliant with RS-422 and RS-485 standards.

Applications

• Industrial control systems requiring robust serial communication interfaces.
• Building automation networks utilizing RS-485 bus topologies.
• Factory automation equipment exposed to electrical noise or voltage transients.

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure the procurement channel provides valid traceability for this Renesas part number to avoid counterfeit components.

Selection Notes

Select this component for applications requiring full-duplex RS-422/RS-485 communication at speeds up to 10 Mbps. It is suitable for designs needing integrated overvoltage protection on I/O lines without external clamping diodes. Consider the 14-SOIC package constraints for PCB layout and thermal management within the specified industrial temperature range.

Part Context

This part belongs to the ISL32470E family of interface ICs from Renesas. It is functionally similar to the non-tape version ISL32470EIBZ but differs in shipping packaging. The series is designed for industrial applications demanding high reliability and fault tolerance in serial communication links.

Replacement Considerations
