ISL83082EIBZ

Drivers, Receivers, Transceivers Overview

The ISL83082EIBZ is a BiCMOS, ESD-protected, 5V-powered single transceiver designed to meet RS-485 and RS-422 standards for balanced communication. It features ±15kV HBM Class 3 ESD protection on all pins without latch-up and is specified for 10% tolerance supplies ranging from 4.5V to 5.5V. The device operates with a data rate of 115 kb/s and supports a true 1/8 unit load, allowing up to 256 devices on the bus. It includes full fail-safe receiver functionality and hot-plug circuitry that keeps outputs in a three-state condition during power-up or power-down. The component is housed in an SOIC-14 package.

Drivers, Receivers, Transceivers Feature Summary

• Full fail-safe receiver operation ensures defined output states under open, short, terminated, or floating conditions.
• Hot-plug capability maintains three-state Tx and Rx outputs during power transitions to prevent bus contention.
• True 1/8 unit load driver architecture enables high node density by supporting up to 256 devices on a single bus.

Drivers, Receivers, Transceivers Applications

• Automated utility meter reading systems
• High node count industrial networks
• Factory automation and field bus networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'BZ' against the manufacturer's current datasheet to confirm RoHS compliance and lead-free status. Confirm the package type matches the required board layout, as suffixes may indicate variations in packaging or material composition. Ensure the ordering quantity aligns with the factory tube packing specifications provided by Renesas Electronics.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single transceiver with robust ESD protection and hot-plug support is required for RS-485 or RS-422 applications. The 1/8 unit load specification makes it suitable for multi-drop networks requiring high device density. Verify that the 5V supply voltage range and 115 kb/s data rate meet the system's electrical requirements.

Drivers, Receivers, Transceivers Part Context

The ISL83082EIBZ belongs to the ISL8308xE family of BiCMOS transceivers manufactured by Renesas Electronics (formerly Intersil). This series is characterized by its compatibility with standard RS-485 and RS-422 protocols while offering enhanced protection features such as ±15kV ESD immunity and thermal shutdown for driver overload protection.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL83082EIUZ serves as a pin-compatible alternative in an MSOP-8 package. Both parts share identical electrical characteristics and functionality within the ISL8308xE family, differing primarily in physical footprint and thermal performance.
