ISL3259EIRZ-T

Drivers, Receivers, Transceivers Overview

The ISL3259EIRZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 5V supply and supports data rates up to 100 Mb/s. The device features IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It utilizes a 10-lead DFN package with dimensions of 3mm x 3mm. The operating temperature range spans from -40°C to +85°C, and the supply voltage range is specified between 4.5V and 5.5V.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high-voltage electrostatic discharge (ESD) protection compliant with IEC 61000-4-2 standards for robust industrial communication environments.
• Supports high-speed data transmission up to 100 Mb/s over differential bus lines for reliable half-duplex operation.
• Designed for low power consumption with a guaranteed shutdown current of less than 1 µA to minimize energy usage during idle periods.

Drivers, Receivers, Transceivers Applications

• Industrial sensor networks requiring robust communication interfaces.
• Building automation systems utilizing RS-485 bus topologies.
• Factory automation equipment needing high ESD immunity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'E' grade corresponds to the extended industrial temperature range of -40°C to +85°C. Ensure the 10-DFN footprint matches the PCB layout requirements. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and authenticity before purchase.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring a compact form factor and high-speed data integrity in electrically noisy environments. The integrated ESD protection reduces the need for external protective components. Compare against similar models like the ISL3259EIRZ if tube packaging is preferred over tape and reel. Verify that the 5V logic levels align with the system's voltage domain.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3259E series of high-speed RS-422/RS-485 transceivers. It is designed to provide reliable communication in harsh industrial settings. The series emphasizes small size and high performance, making it suitable for space-constrained designs. Renesas Electronics produces this line to meet the demands of modern industrial automation and control systems.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL3259EIRZ is a compatible alternative offering identical electrical specifications but packaged in tubes instead of tape and reel. Both parts share the same pinout and functionality. Verify that the change in packaging does not impact the assembly process or inventory handling procedures.
