ISL3259EIBZ

Overview

The ISL3259EIBZ is a half-duplex RS-422/RS-485 interface transceiver manufactured by Renesas Electronics. It integrates one driver and one receiver within a compact DFN-10 package, supporting surface-mount installation. The device operates at a data rate of up to 100 Mb/s with a fixed 5 V supply voltage. It features differential output types and includes an internal receiver input hysteresis of 25 mV to improve noise immunity. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• IEC61000-compliant ESD protection for robust signal integrity in electrically noisy environments
• Low power consumption design suitable for battery-operated or energy-efficient systems
• Integrated thermal shutdown and current limiting for enhanced operational safety

Applications

• Industrial control networks requiring reliable half-duplex communication
• Building automation and security system interfaces
• Metering applications utilizing RS-485 bus topologies

Procurement Notes

Verify the specific suffix 'EIBZ' against the manufacturer's official documentation to confirm the tube packaging format and lead-free status. Ensure the ordering quantity aligns with the standard factory pack size of 100 units per tube. Cross-reference the RoHS compliance details directly with the latest datasheet revision to meet environmental regulations.

Selection Notes

Select this component when a single half-duplex channel is required for RS-422 or RS-485 protocols. The 100 Mb/s speed rating supports high-throughput data transmission needs. The DFN-10 package offers a small footprint ideal for space-constrained PCB layouts. Confirm that the 5 V operating voltage matches the system's power rail requirements.

Part Context

This part belongs to the ISL3259E series of high-speed transceivers designed for harsh industrial environments. It serves as a bridge between low-voltage digital logic and balanced differential transmission lines. The series emphasizes reliability through integrated protection features against electrostatic discharge and bus faults.

Replacement Considerations

The ADM1487EARZ from Analog Devices Inc. is documented as a similar alternative. Verify pinout compatibility and electrical parameter alignment before substitution.
