ISL3152EIBZ-T

Overview

The ISL3152EIBZ-T is a single RS-485/RS-422 differential transceiver manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply and supports data rates up to 1 Mbps. The device features ±15kV IEC61000 ESD protection on the bus pins and >7kV HBM protection on other pins. It incorporates a full fail-safe receiver, hot-plug capability, and current limiting with thermal shutdown for driver overload protection. Packaged in an 8-lead SOIC (Narrow) surface-mount package, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• IEC61000 ESD protection on RS-485 I/O pins
• Full fail-safe receiver design
• Hot plug functionality
• Current limiting and thermal shutdown

Applications

• Remote utility meter reading systems
• Industrial automation networks
• Building automation control systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Renesas Electronics Corporation, noting the historical Intersil branding may appear in legacy documentation. Ensure compliance with RoHS standards and check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component for applications requiring high ESD immunity on RS-485 buses without external protection components. The true 1/8 unit load allows for extensive network topologies. Verify that the 3.3V supply voltage aligns with system power rails and that the 1 Mbps data rate meets communication speed requirements.

Part Context

This part belongs to the ISL315xE series of low-power, high-speed RS-485/RS-422 transceivers. It shares functional similarities with the ISL3172E but is optimized for 3.3V operation with specific ESD characteristics. The series is designed for robust communication in electrically noisy industrial environments.

Replacement Considerations

ISL3172EIBZ-T: Similar RS-485 transceiver with comparable ESD protection and fail-safe features. Verify pinout compatibility and ensure the replacement supports the required 3.3V supply voltage and data rate specifications.
