ISL32435EIUZ-T

Overview

The ISL32435EIUZ-T is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 1 Mbps. The device features 40V overvoltage protection on the bus pins and 15V common-mode rejection capability. It is housed in an MSOP-8 package with dimensions L3.0-W3.0-P0.65-LS4.9-BL. Operating temperatures span from -40°C to +125°C, with a typical operating current of 4.5 mA.

Feature Summary

• Integrated 40V overvoltage protection for robust bus interface
• High common-mode rejection ratio for noise immunity
• Low power consumption with shutdown mode capability

Applications

• RS-485 communication networks
• Industrial automation systems
• Building control applications

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the manufacturer as Renesas or Intersil legacy stock. Ensure the MSOP-8 package matches the required PCB footprint. Check RoHS compliance status for environmental regulations. Validate the temperature grade against system requirements.

Selection Notes

Select this component for half-duplex RS-485 applications requiring high overvoltage tolerance. Compare data rate needs against the 1 Mbps limit. Consider the MSOP-8 package size constraints. Evaluate thermal performance at maximum operating temperatures. Verify compatibility with existing driver logic levels.

Part Context

This part belongs to the ISL3243xE series of low-power RS-485 transceivers. It shares functional similarities with other variants in the family but differs in packaging and specific protection ratings. The series is designed for industrial environments requiring reliable serial communication.

Replacement Considerations

ISL32437EIUZ is a parameter-equivalent alternative available from Renesas. Verify pinout compatibility before substitution. Check if the replacement meets the same overvoltage protection specifications.
