ISL32492EIUZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32492EIUZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver in an 8-lead MSOP package. The device supports data rates up to 250 kbps and operates from a single 5 V supply. It features ±40 V overvoltage protection on the bus pins and ±15 V common mode range, ensuring robust performance in electrically noisy environments. The component includes ESD protection rated at ±15 kV and incorporates fail-safe circuitry to maintain a high output state when inputs are floating.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±40 V fault protection on differential bus pins to withstand transient voltage events
• Fail-safe receiver design ensures a logic high output state during input floating or shorted conditions
• High electromagnetic immunity with ±15 V common mode voltage range capability

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 multi-drop topologies
• Metering infrastructure for utility data acquisition

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 8-MSOP footprint matches the target PCB layout dimensions. Ensure the 5 V supply voltage aligns with the system power architecture before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring standard 250 kbps RS-485 performance with enhanced fault tolerance. The 8-MSOP package is suitable for space-constrained applications. Verify that the ±40 V protection level meets the specific electrical stress requirements of the deployment environment compared to lower-rated alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32492E series of fault-protected transceivers. It shares functional similarities with other members of the family but is distinguished by its specific 5 V operation and MSOP packaging configuration. The series is designed for general-purpose RS-485/RS-422 applications where reliability under harsh electrical conditions is prioritized.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes within the same manufacturer portfolio include ISL32492EIUZ for tube packaging variants. Cross-manufacturer replacements must be evaluated for matching pinout, voltage levels, and protection ratings.
