ISL32485EIBZ-T

Overview

The ISL32485EIBZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates at data rates up to 1 Mbps and requires a single 5 V power supply. The device features high electrostatic discharge (ESD) protection with overvoltage protection (OVP) capabilities, ensuring robust performance in electrically noisy environments. It supports up to 32 unit loads on the bus. The component is housed in an 8-lead SOIC package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated polarity protection prevents damage from incorrect wiring connections.
• High ESD protection ensures reliability against electrostatic discharge events.
• Overvoltage protection safeguards the interface pins from transient voltage spikes.

Applications

• Industrial control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 protocols
• Data acquisition systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the supplier provides traceability for the Renesas Electronics Corporation origin to guarantee authenticity and quality standards.

Selection Notes

Select this component for applications requiring 5V operation with integrated polarity and overvoltage protection. It is suitable for designs needing high ESD immunity without external protection circuits. Consider the 1 Mbps data rate limit and 8-lead SOIC package constraints during PCB layout and system architecture planning.

Part Context

This part belongs to the ISL32485E series of RS-422/RS-485 transceivers. It shares functional similarities with other devices in the family but is distinguished by its specific 5V supply requirement and integrated protection features. The series is designed for industrial and commercial applications demanding robust serial communication interfaces.

Replacement Considerations

Direct pin-to-pin replacements may include variants from the same ISL32485 series with different packaging options. Verify compatibility regarding data rate, supply voltage, and protection specifications before substituting with components from other manufacturers.
