ISL31472EIBZ

Overview

The ISL31472EIBZ is a single RS-485 transceiver manufactured by Renesas Electronics, housed in an SOIC-8 surface-mount package. It operates at a fixed supply voltage of 5 V with a maximum data rate of 250 kb/s. The device supports differential output and includes one driver and one receiver. It functions within a temperature range of -40°C to +85°C and draws 4.5 mA during operation. Key specifications include high overvoltage protection on the bus pins and a common-mode rejection capability of up to -15V.

Feature Summary

• Integrated overvoltage protection for robust bus pin handling
• High common-mode rejection ratio for signal integrity
• Single driver and receiver configuration for point-to-point communication

Applications

• RS-485 half-duplex communication networks
• Industrial automation control systems
• Building automation and security interfaces

Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's current datasheet to confirm RoHS compliance and lead-free status. Ensure the ordering quantity matches the available reel or cut tape packaging options provided by authorized distributors. Confirm the operating temperature grade aligns with the system requirements before finalizing procurement.

Selection Notes

Select this component when a 5 V supply is required for RS-485 applications. It is suitable for designs needing moderate data rates up to 250 kb/s. Consider the SOIC-8 footprint for PCB layout constraints. Verify that the -15V common-mode rejection meets the noise environment requirements of the target application.

Part Context

This part belongs to the ISL31472E series of RS-485 interface ICs from Renesas. It is designed for reliable serial communication in noisy industrial environments. The device integrates standard RS-485 transmitter and receiver circuits into a compact form factor.

Replacement Considerations

Check for direct pin-compatible alternatives within the Renesas ISL314xx family. Verify if other manufacturers offer equivalent 5 V RS-485 transceivers with similar overvoltage protection ratings.
