ISL32432EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL32432EIUZ-T is a half-duplex transceiver supporting RS-422 and RS-485 protocols, manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within an 8-MSOP surface-mount package. The device operates on a supply voltage range of 3V to 5.5V with a data rate capability of 250kbps. It features a receiver hysteresis of 30 mV and functions across a temperature range of -40°C to 85°C. The component includes ±40V fault protection on the bus pins and ±15kV ESD protection, ensuring robust performance in industrial environments.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±40V overvoltage protection on transmitter and receiver I/O pins for enhanced bus safety
• Full fail-safe receiver design ensures a logic high output when inputs are floating or shorted
• Supports standard RS-422 and RS-485 communication protocols with half-duplex operation

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 multi-drop configurations
• Process control instrumentation operating in electrically noisy environments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact packaging and tape-and-reel specifications. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the ordering quantity aligns with the standard factory pack size to avoid partial reel handling issues during assembly.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring compact MSOP packaging with integrated high-voltage fault protection. Verify that the required data rate does not exceed 250kbps and that the supply voltage remains within the 3V to 5.5V operational window. Ensure the application environment stays within the specified -40°C to 85°C temperature range for guaranteed performance.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3243xE series of fault-protected transceivers from Renesas. The series shares common electrical characteristics and pinouts, differing primarily in the number of drivers and receivers. The ISL32432 variant specifically provides a single driver and receiver configuration, distinguishing it from full-duplex or multi-driver counterparts in the same family.

Drivers, Receivers, Transceivers Replacement Considerations

ISL32432EIUZ is a parameter-equivalent alternative without the T7A suffix, offering identical electrical specifications. Other members of the ISL3243xE family may serve as functional substitutes if the pin count and protocol requirements match the system design constraints.
