ISL31472EIBZ-T

Overview

The ISL31472EIBZ-T is a single RS-485 transceiver manufactured by Renesas Electronics. It operates on a fixed 5 V supply voltage and supports data rates up to 250 kb/s. The device features overvoltage protection (OVP) on the bus pins, allowing tolerance of ±15 V common-mode rejection. It includes one driver and one receiver with differential output types. The component functions within an operating temperature range of -40 °C to +85 °C and draws a typical operating supply current of 4.5 mA. It is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrated overvoltage protection for robust operation in electrically noisy industrial environments
• High common-mode rejection capability ensuring reliable signal integrity
• Single-driver configuration optimized for half-duplex communication protocols

Applications

• Industrial automation networks requiring RS-485 connectivity
• Building automation systems utilizing serial communication buses
• Process control instrumentation interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level requirements are addressed during storage and handling procedures to maintain device reliability.

Selection Notes

Select this component for applications requiring 5 V logic compatibility and moderate speed data transmission. The integrated overvoltage protection makes it suitable for harsh electrical environments. Verify that the required data rate does not exceed 250 kb/s and that the system architecture aligns with single-transceiver half-duplex operations.
