ISL32452EIUZ

Drivers, Receivers, Transceivers Overview

The ISL32452EIUZ is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.3 V to 5 V and supports data rates up to 250 kb/s. The device features 60 V overvoltage protection on the bus pins and a common-mode rejection capability of 20 V. It is housed in an 8-lead MSOP package and functions reliably across an operating temperature range of -40 °C to +85 °C. The typical quiescent current is 4.5 mA, and it includes a shutdown mode for power conservation.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 60 V overvoltage protection on differential bus lines
• High common-mode rejection ratio supporting noisy environments
• Low-power shutdown mode reduces standby consumption

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building automation systems
• Metering infrastructure communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A indicates reel packaging when sourcing from distributors. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the MSOP-8 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection against high-voltage transients on RS-485 buses. It is suitable for designs needing low quiescent current and operation with either 3.3 V or 5 V logic supplies. Verify that the 250 kb/s data rate meets the system timing requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32452E series of RS-485 interface ICs. It shares the same core functionality as other variants in the family but differs in packaging and shipping configuration. The EIUZ designation specifies the industrial temperature grade and the MSOP-8 surface-mount package type.

Drivers, Receivers, Transceivers Replacement Considerations

ISL32452EIUZ is listed as a parameter-equivalent replacement for ISL32437EIUZ. Both devices offer similar RS-485 half-duplex capabilities and pinout compatibility.
