ISL32453EIBZ-T

Overview

The ISL32453EIBZ-T is a full-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 60 V overvoltage protection on both the receiver inputs and transmitter outputs, along with a common-mode rejection capability of 20 V. It is housed in a 14-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Full-duplex communication architecture supporting RS-422 and RS-485 protocols
• Integrated 60 V overvoltage protection for robust signal integrity
• High common-mode rejection ratio ensuring reliable noise immunity

Applications

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

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with existing PCB footprints for the 14-SOIC package. Confirm RoHS compliance status through current datasheets as manufacturing sites may change.

Selection Notes

Select this component when full-duplex operation is required alongside high-voltage fault tolerance. Compare against half-duplex alternatives like the ISL32457 if bidirectional single-wire communication suffices. Validate that the 1 Mbps speed meets system timing constraints.

Part Context

This part belongs to the ISL3245xE family of OVP transceivers from Renesas. It shares core protection features with other members but differs in duplex configuration and pin count compared to half-duplex variants.

Replacement Considerations

Publicly confirmed substitutes include the ISL32453EIBZ (tube packaging) or equivalent RS-422/485 transceivers with matching 14-SOIC packages and 60V OVP ratings.
