ISL32498EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL32498EIUZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within an MSOP-8 surface-mount package. The device supports data transmission rates up to 15 Mb/s and operates on a single 5 V supply voltage, with a specified range of 4.5 V to 5.5 V. It functions reliably across an extended industrial temperature range from -40°C to +85°C. Key electrical characteristics include overvoltage protection (OVP) on the I/O pins and high electromagnetic interference immunity.

Drivers, Receivers, Transceivers Feature Summary

• Integrated overvoltage protection on input and output pins for enhanced system robustness
• High noise immunity suitable for electrically noisy industrial environments
• Low power consumption design optimized for battery-operated applications

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the ordering part number matches the exact thermal grade and package variant required for the target PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 5 V operation with high-speed data rates up to 15 Mb/s. The MSOP-8 package is appropriate for space-constrained layouts. Verify that the bus line termination and biasing requirements align with the transceiver's differential input thresholds for reliable communication in multi-drop configurations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32498E series of RS-485/RS-422 interface ICs. It shares functional similarities with other half-duplex transceivers in the Renesas portfolio but is distinct in its specific 15 Mb/s speed rating and 5 V-only operating voltage constraint compared to broader family members.

Drivers, Receivers, Transceivers Replacement Considerations

Consult official substitution guides for pin-compatible alternatives such as the MAX32498 or SN75176 if redesign is necessary. Verify that any substitute maintains the same 15 Mb/s data rate capability and 5 V supply requirement to ensure circuit compatibility.
