ISL32459EIBZ

Overview

The ISL32459EIBZ is a low-power RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It features a single driver and receiver, supporting data rates up to 10 Mbps. The device operates within a supply voltage range of 3V to 5.5V and is housed in an 8-pin SOIC package. It includes overvoltage protection on the I/O pins and offers high common-mode rejection capabilities for reliable communication in noisy environments.

Feature Summary

• Integrated overvoltage protection on transmit and receive pins
• High common-mode noise rejection for robust signal integrity
• Low power consumption suitable for battery-operated systems

Applications

• Industrial automation control networks
• Building automation and security systems
• Point-to-point multipoint communication links

Procurement Notes

Verify the specific suffix 'EIBZ' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering information matches the exact package type and temperature grade required for the target application environment before finalizing procurement.

Selection Notes

Select this component when a single full-duplex or half-duplex channel with high-speed data transmission is required. Consider the 8-pin SOIC footprint for space-constrained designs. Verify that the system voltage aligns with the 3V to 5.5V operating range and that the environmental conditions fall within the specified industrial temperature limits.

Part Context

This part belongs to the ISL3245x family of line transceivers from Intersil, now part of Renesas. These devices are designed for RS-422 and RS-485 applications, offering a balance of speed, power efficiency, and protection features commonly found in industrial and commercial serial communication interfaces.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas portfolio. Verify if newer revisions of the ISL32459 series offer improved specifications or updated packaging options that meet current manufacturing requirements.
