ISL32453EIUZ

Overview

The ISL32453EIUZ is a full-duplex transceiver supporting RS-422 and RS-485 communication protocols, manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within a compact 8-USON package. The device operates on a single power supply ranging from 3V to 5.5V and supports data rates up to 1Mbps. It features an operating temperature range of -40°C to +85°C and includes overvoltage protection (OVP) capabilities. The component is RoHS compliant and classified under EAR99 export control.

Feature Summary

• Integrates overvoltage protection for robust signal line handling
• Supports high common-mode rejection ratios for noise immunity
• Provides full-duplex communication with independent transmit and receive channels

Applications

• Industrial automation systems requiring reliable serial communication
• Building automation networks utilizing RS-485 bus topologies
• Process control instrumentation interfaces

Procurement Notes

Verify the specific suffix EIUZ against official Renesas documentation to confirm the USON-8 package variant, as datasheets often list multiple package options for the base part number. Confirm current lifecycle status, as this family has experienced end-of-life notifications for certain variants. Ensure compliance with RoHS3 standards if required by your manufacturing specifications.

Selection Notes

Select this component when a full-duplex interface is required in space-constrained designs due to its small footprint. Compare against half-duplex alternatives like the ISL31495 if bidirectional single-wire communication suffices. Verify that the 1Mbps speed meets system timing requirements and that the 3V to 5.5V supply range aligns with the target board voltage rails.

Part Context

This part belongs to the ISL3245xE family of OVP transceivers designed for harsh industrial environments. It shares functional similarities with other members of the series but differs in package type and specific pinout configurations. The base model ISL32453 is widely referenced in industrial interface applications.

Replacement Considerations

Publicly confirmed substitutes include the ISL32453EIBZ for SOIC-14 packaging or the ISL32455EIUZ for alternative USON configurations. Verify pin compatibility and electrical parameters before substitution.
