ISL32453EIBZ

Overview

The ISL32453EIBZ is a fully integrated RS-422 and RS-485 transceiver manufactured by Renesas Electronics Corporation. It features one driver and one receiver within a single package, supporting data transmission rates up to 1 Mbps. The device operates on a supply voltage range of 3V to 5.5V and is housed in a 14-SOIC surface-mount package with a width of 3.90mm. It is designed for industrial environments, offering an extended operating temperature range from -40°C to +85°C. The component includes a receiver input hysteresis of 30 mV to improve noise immunity.

Feature Summary

• Supports full-duplex communication protocols including RS-422 and RS-485 standards.
• Integrated overvoltage protection (OVP) capabilities for enhanced signal line safety.
• High common-mode rejection ratio (CMR) to maintain signal integrity in noisy environments.

Applications

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

Procurement Notes

Verify the current lifecycle status before procurement as this specific part number may be subject to end-of-life notices or production changes. Confirm that the 14-SOIC package dimensions align with the target PCB footprint. Ensure the selected variant meets the required thermal and electrical specifications for the intended deployment environment.

Selection Notes

Select this component when a single-channel full-duplex interface is required for RS-422 or RS-485 networks. Consider the 1 Mbps speed limit and 3V to 5.5V operating range against system requirements. Evaluate the 14-SOIC package size constraints relative to available board space and thermal dissipation needs.

Part Context

This device belongs to the ISL3245xE family of OVP transceivers from Renesas. The family shares similar architectural features but varies in channel count and duplex configuration. This specific model provides a single full-duplex path, distinguishing it from half-duplex variants like the ISL32457 or multi-driver models within the same series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components through detailed datasheet comparison if sourcing this obsolete part proves difficult.
