ISL32490EIBZ-T

Drivers, Receivers, Transceivers Overview

The ISL32490EIBZ-T is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 5 V supply and supports data rates up to 250 kb/s. The device features overvoltage protection (OVP) on both the transmit and receive pins, allowing safe operation even when connected to buses with voltages exceeding the supply rail. It is housed in an 8-lead SOIC package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated overvoltage protection on driver and receiver I/O pins
• Half-duplex communication capability for RS-485 networks
• Single 5 V power supply operation

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring robust bus communication
• Building automation and security network interfaces
• Process control instrumentation with exposed bus lines

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring half-duplex RS-485 connectivity with high noise immunity. The integrated overvoltage protection makes it suitable for environments where bus lines may be subjected to transient voltage spikes or accidental connection to higher potential rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3249xE series of RS-485 transceivers designed for harsh electrical environments. The family emphasizes durability through built-in protection mechanisms while maintaining standard interface compatibility for widespread industrial adoption.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements within the same Renesas portfolio include the ISL32490EIBZ (tube packaging). Cross-manufacturer equivalents should be evaluated based on matching OVP ratings, data rate specifications, and package dimensions.
