ISL32430EIUZ

Overview

The ISL32430EIUZ is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mb/s. The device features a 40 V overvoltage protection rating on the bus pins and a common-mode rejection capability of 15 V. It is housed in an 8-lead MSOP package and is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated 40 V overvoltage protection on differential bus lines
• High common-mode rejection ratio supporting noisy industrial environments
• Low power consumption with shutdown mode capability

Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to project requirements. Ensure proper ESD handling procedures are followed during storage and installation to maintain device integrity.

Selection Notes

Select this component when designing circuits requiring robust RS-422 or RS-485 communication with high noise immunity. The 40 V protection feature makes it suitable for harsh industrial environments where transient voltages may occur. Ensure the system voltage aligns with the 3 V to 5.5 V operating range.

Part Context

This part belongs to the ISL3243xE series of low-power, half-duplex RS-422/RS-485 transceivers. The series is characterized by its ability to operate with a wide supply voltage range and provide reliable data transmission in electrically noisy environments. It serves as a key interface solution for connecting microcontrollers to long-distance serial buses.

Replacement Considerations

Check datasheets for compatible alternatives such as the ISL32432EIUZ or ISL32433EIUZ. Verify pin compatibility and electrical specifications before substitution. Ensure that any replacement part meets the same overvoltage protection and data rate requirements.
