ISL32455EIBZ

Drivers, Receivers, Transceivers Overview

The ISL32455EIBZ is a single half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbps. The device features a 60 V overvoltage protection (OVP) rating on the bus pins and a common-mode rejection capability of 20 V. It is housed in an 8-pin SOIC package and functions reliably across an operating temperature range from -40 °C to +85 °C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 60 V overvoltage protection on differential bus pins for enhanced robustness
• High common-mode rejection ratio supporting operation in noisy environments
• Single driver and single receiver configuration for half-duplex communication

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific RoHS compliance status and lead times directly with authorized distributors or Renesas sales representatives, as availability may vary by region. Confirm that the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring half-duplex RS-485 communication with high noise immunity. Ensure the application environment stays within the specified -40 °C to +85 °C temperature range and that the bus line voltage does not exceed the 60 V protection limit.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3245xE family of OVP transceivers designed for reliable serial communication. It complements other interface solutions from Renesas by providing robust protection against electrical faults while maintaining compatibility with standard RS-422 and RS-485 protocols.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the ISL3245x series or newer generations from Renesas. Verify that any substitute maintains the same 60 V OVP rating and 1 Mbps data rate specification.
