ISL3159EIBZ

Drivers, Receivers, Transceivers Overview

The ISL3159EIBZ is a half-duplex RS-485 transceiver manufactured by Renesas Electronics. It integrates one driver and one receiver within an SOIC-8 surface-mount package. The device supports data transmission rates up to 40 Mb/s with a supply voltage range of 4.5 V to 5.5 V. Operating current is specified at 4 mA, while shutdown current drops to 700 µA. It functions reliably across an industrial temperature range from -40°C to +85°C. The component provides differential outputs and includes integrated ESD protection compliant with IEC 61000 standards.

Drivers, Receivers, Transceivers Feature Summary

• IEC 61000-compliant electrostatic discharge protection for bus lines
• Fail-safe receiver design ensures high output during idle states
• Low-power shutdown mode reduces standby consumption significantly

Drivers, Receivers, Transceivers Applications

• Industrial sensor networks requiring robust communication
• Building automation systems utilizing RS-485 buses
• Factory automation control panels

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IBZ' corresponds to the SOIC-8 tube packaging configuration. Confirm RoHS compliance status matches current regulatory requirements. Check manufacturer documentation for any recent production change notices affecting pinout or electrical characteristics before finalizing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single half-duplex channel is sufficient for the application. The SOIC-8 package offers a compact footprint suitable for dense PCB layouts. Ensure the system operates within the 4.5 V to 5.5 V voltage window to maintain signal integrity and meet the 40 Mb/s speed specification without exceeding thermal limits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3159E series of high-speed RS-485 transceivers. It shares core electrical specifications with variants like the ISL3159EFBZ but differs in operating temperature range and physical package dimensions. The series is designed for applications demanding reliable data transfer in electrically noisy environments.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL3159EFBZ serves as a functional alternative offering an extended temperature range up to +125°C. Verify that the package type difference between SOIC-8 and the alternative does not require PCB layout modifications.
