ISL32493EIUZ-T7A

Overview

The ISL32493EIUZ-T7A is a full-duplex RS-422 and RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 1Mbps. The device features ±60V fault protection on the bus lines and provides ±25V common-mode rejection. It includes ESD protection capabilities and functions reliably across an operating temperature range of -40°C to 85°C. The component is housed in a 10-MSOP surface-mount package.

Feature Summary

• Full-duplex communication capability supporting RS-422 and RS-485 protocols
• High robustness with ±60V fault protection on driver and receiver inputs
• Integrated electrostatic discharge (ESD) protection for enhanced signal integrity

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix T7A against current Renesas documentation to confirm tape-and-reel packaging specifications. Confirm that the 10-MSOP package dimensions align with the target PCB footprint. Ensure compliance with RoHS3 standards if required by the end application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when full-duplex operation is required for simultaneous transmission and reception. Choose it for environments requiring high fault tolerance due to the ±60V bus protection feature. Consider it for applications needing ESD protection integrated directly into the interface IC. Verify that the 1Mbps data rate meets the system's throughput requirements.

Part Context

This transceiver belongs to the ISL3249xE series, which focuses on robust industrial interface solutions. The series offers various duplex modes and protection levels tailored for harsh electrical environments. The ISL32493 variant specifically addresses full-duplex needs with high-voltage fault tolerance.

Replacement Considerations

The ISL32496EIUZ-T7A is listed as a parameter-equivalent substitute from Renesas Electronics Corporation.
