ISL31472EIPZ

Overview

The ISL31472EIPZ is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates with a single 5 V supply and supports data rates up to 250 kb/s. The device features overvoltage protection on the differential I/O pins, handling signals from -15 V to +15 V while maintaining normal communication. It is housed in an 8-lead SOIC package and functions within an industrial temperature range of -40 °C to +85 °C. The component includes one driver and one receiver, drawing a typical operating supply current of 4.5 mA.

Feature Summary

• Integrated overvoltage protection for robust operation in electrically noisy environments
• Half-duplex communication capability supporting standard RS-485 protocols
• Low power consumption design suitable for battery-operated systems

Applications

• Industrial automation control networks
• Building automation and security systems
• Point-of-sale (POS) terminals

Procurement Notes

Verify the specific suffix 'IPZ' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Ensure the ordering information matches the exact package type and temperature grade required for the target application environment before finalizing procurement.

Selection Notes

Select this component when a 5 V powered RS-485 interface with high common-mode rejection and overvoltage tolerance is required. Compare against other ISL3147x series variants to ensure the pinout and feature set align with existing board designs. Confirm that the 250 kb/s speed meets the system's latency requirements.

Part Context

This part belongs to the ISL31472E family of RS-485 transceivers. It shares core functionality with other members of the series but differs in packaging and environmental ratings. The IPZ suffix typically denotes a specific tape-and-reel or tube configuration and lead-free manufacturing process defined by the manufacturer.

Replacement Considerations

Check for direct cross-reference part numbers such as the ISL31472EIBZ if package differences are acceptable. Verify electrical compatibility and pin assignments before substituting any alternative transceiver ICs.
