ISL32452EIBZ-T7A

Overview

The ISL32452EIBZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within an 8-pin MSOP package. The device supports data rates up to 250 kbps and operates on a single 3 V to 5.5 V power supply. It features a shutdown mode for low current consumption and includes 60 V overvoltage protection on the I/O pins alongside 20 kV ESD protection per IEC 61000-4-2. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates 60 V overvoltage protection on differential bus pins to withstand fault conditions
• Provides high common-mode rejection capability for reliable signal transmission in noisy environments
• Includes dedicated shutdown pin to minimize power consumption during idle periods
• Offers robust electrostatic discharge protection compliant with industry standards

Applications

• Industrial automation control systems requiring isolated communication links
• Building automation networks utilizing RS-485 multi-drop topologies
• Metering infrastructure for utility data collection applications
• Factory floor equipment interfacing under harsh electrical conditions

Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging when sourcing components. Confirm RoHS3 compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel provides traceable origin records matching the Renesas Electronics Corporation designation to prevent counterfeit infiltration.

Selection Notes

Select this component for designs requiring moderate speed half-duplex communication with enhanced fault tolerance. Compare against standard transceivers if system voltage exceeds 5.5 V or requires higher data throughput. Evaluate thermal management requirements based on the MSOP package constraints and ambient operating temperatures expected in the final assembly environment.

Part Context

This part belongs to the ISL32452E series, which focuses on ruggedized interface solutions for serial communication buses. The family emphasizes durability in electrically noisy industrial settings. The MSOP variant offers a compact footprint suitable for space-constrained printed circuit board layouts compared to larger SOIC packages.

Replacement Considerations

Direct substitutes include other ISL32452 variants such as ISL32452EIBZ for tube packaging. Verify pin compatibility and electrical specifications before swapping between different package types within the same product family.
