ISL3159EIRZ-T

Overview

The ISL3159EIRZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 40 Mbps. The device features a 10-VFDFN package with a bare pad, measuring 3x3 mm. It functions reliably across an extended temperature range from -40°C to +85°C. Key electrical characteristics include a receiver hysteresis of 28 mV and differential output types. The component is RoHS compliant and classified under MSL 3.

Feature Summary

• Supports high-speed data transmission up to 40 Mbps for industrial communication networks
• Integrated fail-safe circuitry ensures a defined receiver output state during idle conditions
• Robust ESD protection capabilities suitable for harsh industrial environments

Applications

• Industrial sensor network solutions requiring reliable half-duplex communication
• Building automation systems utilizing RS-485 bus architectures
• Factory automation equipment interfacing with programmable logic controllers

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm the 10-DFN footprint matches the design layout. Ensure the 4.5V to 5.5V supply requirement aligns with system power rails. Check RoHS compliance status for regulatory adherence. Validate the manufacturer part number against official Renesas documentation before procurement.

Selection Notes

Select this component for applications requiring a compact 3x3mm DFN footprint. Choose this model when operating voltages are strictly between 4.5V and 5.5V. Consider this transceiver for designs needing 40Mbps throughput on RS-485 buses. Verify thermal performance within the -40°C to +85°C range for the target environment. Ensure the half-duplex configuration meets the system's communication protocol requirements.

Part Context

This part belongs to the ISL3159E series of high-speed RS-485 transceivers. It shares functional similarities with other variants in the family but differs in packaging and termination. The IRZ suffix denotes the specific 10-DFN package type. The T suffix typically indicates tape and reel delivery format. This series is designed for robust industrial communication interfaces.

Replacement Considerations

Publicly confirmed substitutes include the ISL3159EIRZ (tube packaging) and ISL3159EIUZ (MSOP-8 package). Verify pin compatibility and thermal characteristics when substituting. Ensure the alternative package fits the existing PCB footprint or allows for re-layout.
