ISL32498EIBZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32498EIBZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within an 8-lead MSOP package, supporting data rates up to 15 Mb/s. The device operates on a single 5 V supply with a typical quiescent current of 2.3 mA. It features overvoltage protection on both the transmit (TXD) and receive (RXD) inputs, as well as on the differential bus lines (A and B), allowing safe operation even when powered down. The component is rated for an extended industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated overvoltage protection on all pins ensures robust performance in high-voltage fault conditions.
• High-speed data transmission capability supports baud rates up to 15 Mb/s for efficient communication.
• Low power consumption design facilitates battery-operated applications with minimal energy usage.
• Fail-safe receiver guarantees a high logic output state when the differential input is open or floating.

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring reliable serial communication.
• Building automation networks utilizing RS-485 bus topologies.
• Point-of-sale terminals and payment systems needing secure data links.
• Medical equipment interfaces demanding noise immunity and low power.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure the MSOP-8 footprint matches the PCB layout constraints. Check for any recent Product Change Notices regarding material or assembly updates.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed half-duplex communication with integrated pin protection. Compare against the ISL32498EIUZ variant if tube packaging is preferred over reel. Consider the ISL31492EIBZ-T7A if lower data rates suffice but SOIC-8 packaging is required. Verify voltage levels match the system's 5 V logic requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32498E family of high-speed RS-422/RS-485 transceivers. It shares core electrical characteristics with other members like the ISL32498EIUZ but differs in package type and shipping configuration. The series is designed for harsh electromagnetic environments common in industrial settings.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL32498EIUZ serves as a direct functional equivalent in a tube package. For legacy replacements, verify compatibility with older Intersil-branded parts. No cross-compatible alternatives from other manufacturers are confirmed in public datasheets without additional validation.
