ISL32435EIUZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32435EIUZ-T7A 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 8-MSOP package with dimensions of 0.118 inches (3.00mm) width. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±40V fault protection on driver and receiver I/O pins to withstand bus faults and ESD events.
• Supports high-speed data transmission at rates up to 1 Mbps for efficient serial communication.
• Operates with standard 3.3V and 5V power supplies, ensuring compatibility with various logic levels.

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring robust noise immunity
• Building automation networks utilizing RS-485 multi-drop configurations

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A corresponds to tape-and-reel packaging when ordering. Confirm the manufacturer designation as Renesas Electronics Corporation, noting its historical association with Intersil. Ensure the order matches the exact part number to guarantee the specified 8-MSOP package and operational characteristics are delivered.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring RS-485 connectivity with enhanced fault tolerance. The ±40V protection makes it suitable for noisy industrial settings where bus line damage is a risk. Verify that the 1 Mbps data rate meets system timing requirements and that the 8-MSOP footprint fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3243xE series of fault-protected transceivers. It shares architectural similarities with models like the ISL32432E but offers higher data rate capabilities. The series is designed for reliable operation in electrically noisy environments, providing a balance between performance and ruggedness for interface applications.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other members of the ISL3243xE family such as the ISL32432EIUZ or ISL32433EIUZ, provided pinout and protocol compatibility are verified. Cross-reference datasheets to ensure equivalent fault protection levels and operating temperature ranges before substitution.
