ISL32457EIBZ

Drivers, Receivers, Transceivers Overview

The ISL32457EIBZ is a half-duplex RS-422 and RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within an 8-SOIC surface-mount package. The device operates on a single power supply ranging from 3V to 5.5V and supports data transmission rates up to 1Mbps. It features a common-mode rejection capability of 20V and includes 60V overvoltage protection on both the receiver input and the driver output. The component functions reliably across an extended industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 60V overvoltage protection safeguards the receiver input and driver output against transient voltage events.
• High common-mode rejection ratio ensures reliable signal integrity in electrically noisy industrial environments.
• Supports standard RS-422 and RS-485 communication protocols for robust serial data transmission.

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring isolated serial communication
• Building automation networks utilizing RS-485 bus topologies
• Factory equipment interfaces subject to electrical noise and voltage spikes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix designation, as the base part number may correspond to different packaging options such as tubes or tape-and-reel configurations. Confirm current availability status, as this component has been subject to discontinuance notices. Ensure compliance with RoHS3 standards and check moisture sensitivity level ratings prior to soldering processes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require half-duplex communication with enhanced protection capabilities. The 8-SOIC package is suitable for space-constrained layouts. Consider the 1Mbps data rate limit and the 3V to 5.5V operating voltage range to ensure compatibility with the target system's logic levels and power infrastructure.

Drivers, Receivers, Transceivers Part Context

This device belongs to the ISL3245xE family of overvoltage protected transceivers. It shares functional similarities with other models in the series, such as the ISL32453 and ISL32455, but differs in duplex mode and package configuration. The EIBZ suffix specifically denotes the 8-SOIC tube packaging variant.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL32457EIBZ is listed as obsolete. Potential replacements include the ISL32457EIBZ without the trailing suffix or other members of the ISL3245x family. Verify pinout compatibility and electrical specifications before substituting.
