ISL32498EIUZ

Overview

The ISL32498EIUZ is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates at a fixed supply voltage of 5 V and supports data transmission rates up to 15 Mb/s. The device features one driver and one receiver with differential output types. It is housed in an MSOP-8 surface-mount package and functions within a temperature range of -40°C to +85°C. Key electrical characteristics include integrated ESD protection and overvoltage protection (OVP) capabilities, ensuring reliable operation in industrial communication environments.

Feature Summary

• Integrated overvoltage protection for robust signal line handling
• High-speed data transmission capability up to 15 Mb/s
• Built-in electrostatic discharge protection mechanisms

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific ordering suffix EIUZ to confirm the MSOP-8 package type and RoHS compliance status before procurement. Ensure that the 5 V supply requirement aligns with the target system design. Confirm the operating temperature range meets the environmental specifications of the intended deployment location. Cross-reference the manufacturer part number with official Renesas documentation to avoid counterfeit components.

Selection Notes

Select this component when a single-channel RS-422 or RS-485 interface is required in a compact MSOP-8 footprint. It is suitable for designs needing 15 Mb/s throughput with 5 V logic levels. Consider the OVP and ESD features for noisy industrial environments. Verify compatibility with existing PCB layout constraints and thermal management requirements for the small outline package.

Part Context

This component belongs to the ISL32498E series of high-performance RS-422/RS-485 transceivers. It is part of Renesas' broader portfolio of interface ICs designed for reliable serial communication. The series emphasizes durability through integrated protection features, making it a standard choice for legacy and modern industrial bus applications requiring differential signaling.

Replacement Considerations

Consult official Renesas documentation for direct pin-compatible substitutes within the same family. Verify that any alternative component matches the 5 V supply, 15 Mb/s speed, and MSOP-8 package dimensions. Ensure equivalent OVP and ESD ratings are maintained for system reliability.
