ISL32704EIBZ

Drivers, Receivers, Transceivers Overview

The ISL32704EIBZ is a low-EMI, galvanically isolated half-duplex RS-485 transceiver manufactured by Renesas Electronics. It integrates an on-chip isolated DC/DC converter to provide a self-contained isolated power supply for the high-side circuitry. The device supports data rates up to 4 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. It features a QSOP-16 package with a wide operating temperature range from -40°C to +85°C. Key electrical specifications include a maximum output current of 60 mA, a quiescent supply current of 4 mA, and ESD protection rated at 15 kV.

Drivers, Receivers, Transceivers Feature Summary

• Galvanic isolation between logic and bus sides via integrated DC/DC converter
• Low electromagnetic interference (EMI) design for signal integrity
• Half-duplex communication capability for RS-485 networks

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation and security networks
• Factory floor instrumentation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks in the secondary market. Confirm RoHS compliance status and specific packaging variants such as tube quantities against official datasheets before finalizing orders. Ensure compatibility with existing PCB footprints for the QSOP-16 package.

Drivers, Receivers, Transceivers Selection Notes

Select this component when galvanic isolation is required for RS-485 applications without external isolation barriers. It is suitable for designs needing low EMI emissions and moderate data rates up to 4 Mb/s. Consider thermal management requirements given the power dissipation characteristics and ensure the system voltage aligns with the 3 V to 5.5 V operating range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32704E series of isolated transceivers. It shares functional similarities with other members like the ISL32705EIBZ but differs in duplex mode; the ISL32704EIBZ is half-duplex while others may be full-duplex. The 'BZ' suffix typically denotes the specific package type and lead-free composition.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative isolated RS-485 transceivers based on pin compatibility and isolation voltage ratings if direct replacements are needed.
