ISL32470EIBZ

Overview

The ISL32470EIBZ is a fully compliant RS-422 and RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within a 14-pin SOIC package. The device operates on a single 5V supply, supporting data rates up to 250kbps. It features a common-mode rejection range of ±20V and includes overvoltage protection rated at 60V on the bus pins. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated overvoltage protection on differential bus lines
• High common-mode noise rejection capability
• Compliant with RS-422 and RS-485 communication standards

Applications

• Industrial control systems requiring robust serial communication
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix 'BZ' against current manufacturer documentation to confirm packaging type and RoHS compliance status. Confirm availability as distribution channels may list obsolete or discontinued stock for this part number. Ensure the ordering quantity matches the standard tube packaging requirements specified in the official datasheet.

Selection Notes

Select this component when a single full-duplex transceiver is required for RS-422 or RS-485 networks. The 14-pin SOIC package suits applications needing compact surface-mount solutions. Verify that the 250kbps data rate meets system timing requirements and that the 60V overvoltage protection aligns with the electrical environment of the target application.

Part Context

This device belongs to the ISL3247xE series of high-performance interface ICs. The series is characterized by its ability to withstand harsh electrical environments through integrated protection features. It serves as a core connectivity component for reliable half-duplex or full-duplex data transmission in industrial settings.

Replacement Considerations

ISL32470EIBZ-T is available as a tape-and-reel variant of the same functional device.
