ISL32437EIUZ-T

Overview

The ISL32437EIUZ-T is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation, housed in an 8-pin MSOP surface-mount package. It supports data rates of up to 1 Mb/s and operates on supply voltages of 3.3 V or 5 V. The device features 40 V overvoltage protection (OVP) on the bus pins and includes a shutdown mode for power conservation. It functions within an extended industrial temperature range from -40°C to +125°C and draws a typical operating current of 4.5 mA.

Feature Summary

• Integrated 40V overvoltage protection on differential bus lines
• Low-power shutdown control pin for energy management
• Compliant with RS-485 and RS-422 communication standards

Applications

• Industrial automation fieldbus networks
• Building automation systems
• Factory process control instrumentation

Procurement Notes

Verify the specific suffix 'T' against official datasheets to confirm reel packaging requirements. Ensure the selected variant matches the required voltage and temperature specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring robust bus protection against transient voltages. The MSOP-8 package is suitable for space-constrained PCB layouts. Confirm compatibility with the system's logic levels and baud rate requirements prior to integration into the design.

Part Context

This part belongs to the ISL32437E series of interface ICs designed for reliable serial communication. It serves as a bridge between microprocessors and balanced transmission lines, ensuring signal integrity in electrically noisy environments common in industrial settings.

Replacement Considerations

ISL32437EIUZ is a tube-packaged equivalent. ISL32432EIUZ and ISL32452EIUZ are listed as parameter-equivalent alternatives.
