ISL3159EIBZ-T

Overview

The ISL3159EIBZ-T is a high-speed RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 5 V supply and supports data rates up to 40 Mb/s. The device integrates one driver and one receiver in an SOIC-8 surface-mount package. It functions as a half-duplex transceiver with differential output types. The operational temperature range spans from -40 °C to +85 °C. Supply voltage limits are defined between 4.75 V and 5.25 V, with a typical operating current of 4 mA.

Feature Summary

• Supports high-speed data transmission up to 40 Mb/s for efficient communication
• Integrates ESD protection compliant with IEC 61000 standards for robust signal integrity
• Features low standby current consumption to optimize power efficiency

Applications

• Industrial sensor networks requiring reliable half-duplex communication
• Building automation systems utilizing RS-485 bus topologies
• Factory automation equipment needing high-speed data transfer capabilities

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the manufacturer designation matches Renesas Electronics or Intersil legacy branding. Ensure the SOIC-8 package type aligns with PCB footprint requirements. Check RoHS compliance status for environmental regulations. Validate the moisture sensitivity level before storage and reflow soldering processes.

Selection Notes

Select this component for applications requiring 40 Mb/s throughput on a 5 V system. Compare against lower-speed variants like the ISL3155E if bandwidth demands are reduced. Consider the ISL3159EIRZ for DFN package constraints instead of SOIC-8. Evaluate thermal dissipation needs within the specified industrial temperature range. Verify compatibility with existing RS-485 network protocols and termination strategies.

Part Context

This part belongs to the ISL3159E series of RS-422/RS-485 interface ICs. It represents a transition from Intersil heritage products now managed by Renesas Electronics. The series focuses on high-speed, ruggedized communication interfaces for industrial environments. It complements other transceivers offering varying speed and package options within the same functional family.

Replacement Considerations

ISL3159EIBZ serves as a direct replacement for older Intersil ISL3159EIBZ units. The ISL3159EIRZ offers identical electrical performance in a different DFN package. Verify pinout compatibility when substituting across package types. Ensure voltage levels remain consistent at 5 V for both driver and receiver sections.
